Special Populations: Pediatric, Geriatric, and Obstetric Patients - NREMT EMT Level

SECTION 1

Historical Context & Motivation

For much of the twentieth century, emergency medical services (EMS) operated under a one-size-fits-all treatment model, applying adult protocols to every patient regardless of age, developmental status, or pregnancy. This approach produced measurable harm: medication dosing errors in children, missed presentations of myocardial infarction in the elderly, and preventable complications during emergency field deliveries. Over several decades, landmark research and advocacy initiatives demonstrated that pediatric, geriatric, and obstetric patients each possess distinct physiological profiles that demand tailored prehospital care. The evolution of population-specific EMS protocols represents one of the most significant quality improvements in modern prehospital medicine.

1966 • "Accidental Death and Disability" Report

The National Academy of Sciences publishes its landmark white paper, exposing critical deficiencies in emergency care across the United States and catalyzing the development of organized EMS systems. The report made no specific provisions for special populations, but it laid the groundwork for all future reforms.

1984 • EMSC Program Established

Congress authorizes the Emergency Medical Services for Children (EMSC) program under HRSA, acknowledging that children have unique prehospital needs and that providers require specialized training, equipment, and protocols.

1996 • Broselow Tape Gains Wide Adoption

The length-based resuscitation tape developed by Dr. James Broselow becomes standard EMS equipment nationwide, providing rapid weight estimation and drug dosing for pediatric patients and reducing medication errors significantly.

2006 • GEM Guidelines Published

The Geriatric Education for EMS (GEMS) course is released, formalizing age-specific assessment strategies for the growing elderly population, including recognition of atypical symptom presentations and polypharmacy considerations.

2020 • Updated NREMT Competencies

The National Registry of Emergency Medical Technicians revises its testing blueprint to give greater emphasis to special populations, ensuring that all certified EMTs demonstrate competency in pediatric, geriatric, and obstetric assessment, treatment, and transport decision-making.

The central question that drove these reforms remains the animating concern of this lesson: How must EMTs modify their standard assessment and treatment algorithms when the patient is a child, an older adult, or a pregnant woman? Answering this question requires understanding the anatomical, physiological, pharmacological, and psychosocial differences that define each special population—differences that, if ignored, can turn a routine call into a preventable tragedy.

SECTION 2

Core Principles of Special-Population Care

Effective prehospital care for special populations rests on several foundational principles that distinguish these patients from the standard adult model. These principles guide every step of the EMT's clinical decision-making, from scene size-up through hospital handoff. Rather than memorizing isolated facts, the competent provider internalizes these principles and applies them dynamically to each unique patient encounter.

Anatomical & Physiological Variation

Children have proportionally larger heads and tongues, compliant chest walls, and faster metabolic rates. Elderly patients exhibit decreased physiological reserve, osteoporotic bones, and altered thermoregulation. Pregnant patients experience increased blood volume, a displaced diaphragm, and supine hypotensive syndrome. Each variation demands modified assessment techniques.

Age-Appropriate Communication

Pediatric patients require communication calibrated to developmental stage—toddlers need simple language and parental proximity, while adolescents deserve respectful autonomy. Geriatric patients may have sensory deficits requiring louder, slower speech or written communication. Obstetric patients benefit from calm reassurance addressing both maternal and fetal concerns.

Weight-Based & Adjusted Interventions

Pediatric medication doses, airway equipment sizes, and fluid volumes are weight-dependent. Geriatric patients may require lower doses due to decreased renal and hepatic clearance. Obstetric patients necessitate left lateral positioning and awareness of medications contraindicated in pregnancy.

Two-Patient Paradigm in Obstetrics

The pregnant patient always represents two patients: mother and fetus. Interventions that benefit the mother—supplemental oxygen, IV fluid resuscitation, left lateral tilt—simultaneously support fetal well-being. The EMT must continuously consider dual impacts of every treatment decision.

Transport Decision Complexity

Special populations often require transport to specialty receiving facilities—pediatric trauma centers, stroke centers with geriatric expertise, or hospitals with labor and delivery units—rather than the nearest emergency department. Destination decisions carry outsized significance for patient outcomes.

✦

KEY TAKEAWAY

Think of special-population care like adjusting the settings on a sophisticated instrument. The underlying principles of patient assessment remain constant—just as a guitar still has six strings regardless of genre—but the tuning must change. A pediatric patient requires smaller equipment and weight-based dosing (higher pitch), a geriatric patient demands awareness of comorbidities and polypharmacy (different key), and an obstetric patient introduces a second performer entirely (a duet). Mastering these adjustments is what separates competent EMTs from merely certified ones.

SECTION 3

Anatomical Comparison Across Populations

Understanding why special populations require modified care begins with visualizing the critical anatomical differences that distinguish pediatric, adult, geriatric, and obstetric patients. The following diagram illustrates key structural variations relevant to airway management, trauma assessment, and circulatory considerations—three domains where errors are most consequential in the prehospital setting.

This diagram compares the four patient profiles an EMT may encounter. Note the pediatric patient's proportionally larger head and funnel-shaped airway, the geriatric patient's kyphotic posture and rigid chest, and the obstetric patient's enlarged uterus displacing the diaphragm superiorly and compressing the inferior vena cava in the supine position.

The visual comparison above underscores a critical principle: what is normal varies dramatically across populations. A heart rate of 140 beats per minute is tachycardia in an adult but may be within the normal range for an infant. A blood pressure of 100/70 mmHg may seem adequate in a pregnant patient at 36 weeks, but it could represent significant hemorrhage given the 30–50% increase in circulating blood volume that occurs during pregnancy. Similarly, an elderly patient on beta-blockers may fail to mount the expected tachycardic response to hypovolemia, masking the severity of shock until decompensation is imminent. These nuances demand that EMTs internalize population-specific normal ranges and recognize deviations in context rather than relying on universal thresholds.

SECTION 4

Physiological Mechanisms Behind the Differences

The clinical differences among special populations are not arbitrary—they arise from well-understood physiological mechanisms. This section examines the mechanistic basis for the assessment modifications described earlier, organized by population. Understanding why these differences exist—rather than merely memorizing that they do—enables the EMT to reason through unfamiliar scenarios and adapt protocols when textbook situations fail to materialize.

Pediatric Physiology

Children are not small adults. The pediatric airway is anatomically narrower and more anterior, with the narrowest point at the cricoid ring (rather than at the vocal cords, as in adults), creating a funnel-shaped passage that is highly susceptible to obstruction from even minor edema or secretions. The large, floppy epiglottis and proportionally larger tongue further complicate airway management. Metabolically, children have a higher body surface area-to-mass ratio, which accelerates heat loss and makes hypothermia a constant threat during prolonged field care. Their limited glycogen stores mean that hypoglycemia develops more rapidly during stress or illness. Cardiovascular compensation in children relies heavily on heart rate rather than stroke volume, so bradycardia in a child is an ominous sign suggesting imminent cardiovascular collapse—a fundamentally different interpretation than in adults, where bradycardia may be benign.

Geriatric Physiology

Aging produces a progressive decline in physiological reserve—the body's capacity to compensate for acute physiological stress. Cardiac output decreases approximately 1% per year after age 30, and arterial stiffening increases systolic blood pressure while reducing the baroreceptor reflex that normally maintains perfusion during position changes (contributing to orthostatic hypotension). Respiratory function declines as the chest wall calcifies and the alveoli lose elasticity, reducing vital capacity and gas exchange efficiency. Renal function diminishes—glomerular filtration rate decreases by approximately 1 mL/min per year after age 40—which prolongs drug half-lives and increases susceptibility to medication toxicity. The cumulative effect is that geriatric patients decompensate more rapidly, present with atypical symptoms (such as painless myocardial infarction or afebrile sepsis), and recover more slowly. The phenomenon of polypharmacy (the concurrent use of five or more medications) compounds these vulnerabilities by introducing drug-drug interactions that can mimic or mask acute illness.

Obstetric Physiology

Pregnancy induces profound cardiovascular adaptations to support the developing fetus. Blood volume increases by 30–50% by the third trimester, and cardiac output rises approximately 40%. While these changes provide a buffer against hemorrhage, they also mean that a pregnant patient can lose a significant volume of blood before exhibiting classic signs of shock—a phenomenon known as physiological masking. Resting heart rate increases by 10–20 beats per minute, and blood pressure decreases slightly during the second trimester before returning toward baseline in the third. After approximately 20 weeks of gestation, the gravid uterus compresses the inferior vena cava when the patient is supine, reducing venous return and cardiac output by up to 30%—this is supine hypotensive syndrome, managed by placing the patient in the left lateral recumbent position or tilting the backboard 15–30 degrees to the left.

⚠

Clinical Pearl

In a trauma scenario involving a visibly pregnant patient beyond 20 weeks, always tilt the spine board 15–30 degrees to the left or manually displace the uterus leftward. Failure to relieve aortocaval compression can reduce cardiac output by up to 30%, turning a stable patient into a crashing one.

SECTION 5

Population-Specific Assessment Strategies

Accurate assessment forms the foundation of effective prehospital treatment. For special populations, the standard primary and secondary survey algorithms must be modified to account for different normal values, altered symptom presentations, and unique assessment tools. The following diagram provides a decision-support framework that EMTs can reference when evaluating pediatric, geriatric, and obstetric patients in the field.

This flowchart guides the EMT through population-specific assessment steps from patient identification through transport decisions. Note the distinct red-flag warnings (⚠) for each population and the common endpoint of selecting an appropriate specialty receiving facility.

The Pediatric Assessment Triangle (PAT)

The Pediatric Assessment Triangle is a rapid, hands-off assessment tool performed within the first 30 seconds of a pediatric encounter. It evaluates three components: appearance (muscle tone, interactiveness, consolability, look/gaze, and speech/cry—remembered by the mnemonic TICLS), work of breathing (nasal flaring, retractions, head bobbing, audible sounds), and circulation to skin (pallor, mottling, cyanosis). The PAT allows the EMT to form a general impression of the child's acuity—stable, distressed, or failing—before initiating any hands-on assessment, which is particularly important because physical contact can provoke agitation in young children, artificially altering vital signs.

Geriatric Assessment: The GEMS Diamond

The GEMS diamond provides a structured framework for geriatric assessment, guiding the EMT to evaluate four domains: Geriatric considerations (is the patient's presentation typical of aging versus acute illness?), Environmental assessment (trip hazards, heating adequacy, medication bottles, signs of neglect or abuse), Medical assessment (medication reconciliation, comorbidity inventory, baseline mental status from caregivers), and Social assessment (support network, activities of daily living, advance directives). This comprehensive approach helps distinguish acute pathology from chronic baseline conditions, a distinction that is frequently challenging in the elderly population.

Assessment Feature	Pediatric	Geriatric	Obstetric
Primary Tool	PAT (Pediatric Assessment Triangle)	GEMS Diamond	Gestational age + contraction timing
Vital Sign Caveat	Age-dependent normal ranges; bradycardia is ominous	Medications may mask tachycardia or hypertension	Baseline HR ↑ 10–20 bpm; BP slightly ↓ in 2nd trimester
Exam Approach	Toe-to-head; minimize separation from caregiver	Head-to-toe; thorough medication and environment review	Standard + fundal height, visual for crowning
Key Red Flag	Unresponsiveness, apnea, or bradycardia	Acute altered mental status from baseline	Seizure, severe HTN, or vaginal hemorrhage
Transport Destination	Pediatric trauma/medical center	Stroke center or geriatric-capable ED	Hospital with labor and delivery unit

SECTION 6

Worked Example: Field Management of a Pediatric Respiratory Emergency

The following scenario demonstrates the systematic application of special-population principles to a pediatric patient presenting with respiratory distress. This example integrates assessment, equipment selection, treatment, and transport decision-making into a cohesive clinical workflow.

Scenario: 3-Year-Old with Stridor and Respiratory Distress

1
Step 1 — Scene Size-Up and General Impression

You arrive at a residence where a 3-year-old male is sitting upright on his mother's lap. He has audible inspiratory stridor and appears anxious. You perform the Pediatric Assessment Triangle (PAT) from the doorway: Appearance shows an alert but anxious child with decreased interactiveness; Work of Breathing reveals visible suprasternal and intercostal retractions with stridor; Circulation to Skin is adequate with pink, warm skin. General impression: respiratory distress, upper airway.

PAT: Abnormal appearance + increased work of breathing = upper airway obstruction with respiratory distress
2
Step 2 — Primary Assessment with Age-Appropriate Modifications

You approach the child calmly and perform a toe-to-head assessment while the child remains on the mother's lap to minimize agitation. Heart rate is 140 bpm (within normal range for a 3-year-old: 80–140 bpm), respiratory rate is 34/min (elevated; normal for age is 20–30/min), SpO₂ is 93% on room air, and temperature is 38.8°C (102°F). You note a barking, seal-like cough consistent with croup (laryngotracheobronchitis). You use the Broselow tape, which measures the child at approximately 14 kg.

Vital signs: HR 140, RR 34, SpO₂ 93%, Temp 38.8°C. Weight ≈ 14 kg (Broselow tape)
3
Step 3 — Treatment Interventions

You administer humidified blow-by oxygen via a pediatric non-rebreather mask held near the child's face (avoiding placement directly on the face to prevent agitation and worsening of stridor). You keep the child in a position of comfort on the mother's lap and avoid direct examination of the oropharynx, which could worsen upper airway edema and obstruction. You ensure the ambulance is warm to prevent hypothermia, recognizing the child's high body surface area-to-mass ratio.

Interventions: blow-by O₂, position of comfort, maintain warmth, avoid agitating the child
4
Step 4 — Reassessment and Trending

After 5 minutes of blow-by oxygen, you reassess: SpO₂ has improved to 96%, respiratory rate has decreased to 28/min, and stridor is audible only with agitation. The PAT now shows improved appearance with more interactiveness. You continue monitoring and document vital sign trends every 5 minutes, recognizing that children can decompensate rapidly from respiratory distress to respiratory failure.

Post-intervention: SpO₂ 96%, RR 28—improving but continued monitoring essential
5
Step 5 — Transport Decision and Handoff

You elect to transport to the nearest hospital with a pediatric emergency department, 12 minutes away, rather than the closest general ED, which is 6 minutes away. During transport, the child remains on the mother's lap (secured per local protocol). You radio the receiving facility with a SBAR report emphasizing the child's age, weight, suspected croup with improving stridor, and current vital signs. On arrival, you provide a detailed handoff including Broselow color zone, interventions performed, and vital sign trends.

SECTION 7

Common Errors and Best Practices by Population

Clinical errors in special-population care frequently arise not from ignorance but from the inappropriate application of adult-centric protocols. Understanding the most common pitfalls for each population helps the EMT develop the clinical vigilance necessary to avoid them. The following table contrasts frequent errors with evidence-based best practices, organized by population.

Population	Common Error	Best Practice
Pediatric	Using adult-sized airway equipment; estimating drug doses without Broselow tape	Always use length-based tape for weight estimation; select appropriately sized equipment from the corresponding color zone
Pediatric	Hyperextending the neck for airway positioning	Use neutral sniffing position; place a thin pad under the shoulders to compensate for the large occiput
Geriatric	Dismissing confusion as "normal aging" or "dementia"	Always determine baseline mental status from caregivers; acute changes warrant aggressive workup for stroke, infection, or metabolic emergency
Geriatric	Failing to collect all medications from the scene	Gather all medication bottles (including OTC and supplements) and bring them to the hospital for reconciliation
Obstetric	Transporting a third-trimester patient supine on a flat backboard	Tilt the backboard 15–30° left or manually displace the uterus to prevent supine hypotensive syndrome
Obstetric	Interpreting normal pregnancy vital signs as pathological (e.g., HR 110 as tachycardia)	Recognize that HR increases 10–20 bpm and BP decreases slightly during pregnancy; adjust thresholds accordingly

Common errors vs. best practices in special-population prehospital care

✦

KEY TAKEAWAY

The most dangerous errors in special-population care are errors of assumption—assuming adult normals apply universally, assuming confusion in the elderly is chronic, or assuming a pregnant patient's stable-looking vital signs reflect hemodynamic stability. Think of each special population as requiring a different clinical lens: the same vital sign reading, viewed through the pediatric, geriatric, or obstetric lens, may carry an entirely different clinical significance. Developing the reflexive habit of switching lenses at the moment of patient identification is the hallmark of the skilled prehospital provider.

SECTION 8

Connection to Advanced Prehospital and In-Hospital Care

The EMT-level assessment and treatment principles for special populations form the foundation upon which advanced providers—Advanced EMTs (AEMTs) and Paramedics—build more complex interventions. Understanding how basic EMT competencies connect to advanced care allows the EMT to anticipate the needs of receiving providers, prioritize critical information during handoffs, and recognize the rationale behind the treatments they observe during interfacility transfers.

Domain	EMT-Level Intervention	Advanced-Level Extension
Pediatric Airway	OPA/NPA sizing, BVM with appropriate mask, blow-by O₂, suctioning	Endotracheal intubation with cuffed/uncuffed tube selection, RSI medications, advanced supraglottic airways
Pediatric Cardiac	CPR with age-appropriate compression depth/rate, AED with pediatric pads/attenuator	IV/IO access, epinephrine at weight-based dose, cardiac rhythm interpretation, synchronized cardioversion
Geriatric Pain	Splinting, positioning, ice/heat, verbal reassurance, transport to appropriate facility	IV analgesics with reduced dosing, 12-lead ECG interpretation for atypical MI, point-of-care glucose and lactate testing
Obstetric Emergency	Left lateral positioning, emergency delivery assistance, neonatal resuscitation basics (stimulation, warmth, BVM)	IV oxytocin for postpartum hemorrhage, magnesium sulfate for eclampsia, breech delivery techniques, surgical cricothyrotomy
Pharmacology	Oral glucose, aspirin, epinephrine auto-injector, activated charcoal (where authorized)	Full weight-based pharmacology including analgesics, antiarrhythmics, vasopressors, and population-specific contraindication awareness

EMT-level competencies vs. advanced provider extensions for special populations

The trajectory from EMT to Paramedic represents not a fundamental change in clinical philosophy but an expansion of the therapeutic toolkit available to implement that philosophy. The core principles—population-specific normals, modified assessment techniques, weight-based thinking, and two-patient awareness in obstetrics—remain constant across all levels of prehospital certification. Mastery at the EMT level creates the cognitive framework upon which advanced skills are layered, making this foundational knowledge essential even for those who plan to pursue paramedic certification.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

Explain why bradycardia is considered an ominous sign in a pediatric patient but may be a normal finding in a healthy adult. What physiological mechanism underlies this critical distinction?

Show answer

Pediatric patients have relatively fixed stroke volumes and rely primarily on heart rate to maintain cardiac output (CO = HR × SV). When a child's heart rate drops, cardiac output falls precipitously because the immature myocardium cannot compensate by significantly increasing stroke volume. In contrast, healthy adults have compliant ventricles capable of augmenting stroke volume to maintain perfusion even at lower heart rates, as described by the Frank-Starling mechanism. Therefore, bradycardia in a child typically represents the exhaustion of compensatory mechanisms and signals imminent cardiovascular collapse—a pre-arrest rhythm—whereas in an adult athlete, a resting heart rate of 50 bpm may simply reflect efficient cardiac function and high vagal tone.

Question 2: BASIC CALCULATION

A pregnant patient at 34 weeks gestation is involved in a motor vehicle collision. Her pre-pregnancy blood volume was approximately 5,000 mL. Assuming a 40% increase in blood volume during pregnancy, what is her estimated current blood volume? If she loses 1,500 mL from internal hemorrhage, what percentage of her total blood volume has she lost, and would you expect classic signs of shock at this volume?

Show answer

Her estimated current blood volume is 5,000 mL × 1.40 = 7,000 mL. A loss of 1,500 mL represents 1,500 ÷ 7,000 ≈ 21.4% of her total blood volume. In a non-pregnant adult, loss of approximately 15–30% of blood volume (Class II hemorrhage) would typically produce tachycardia, anxiety, and narrowed pulse pressure. However, because the pregnant patient has 2,000 mL of "extra" blood volume acting as a buffer, she may not display classic shock signs until her losses are more severe. This is physiological masking—the EMT must maintain a high index of suspicion for occult hemorrhage in pregnant trauma patients and not be reassured by apparently stable vital signs.

Question 3: INTERMEDIATE

You respond to an 82-year-old female who fell at home. She is alert and oriented, denies chest pain, and has the following vitals: HR 78, BP 142/88, RR 18, SpO₂ 95%. Her daughter reports that the patient takes metoprolol, lisinopril, warfarin, and metformin. Describe how each medication could complicate your assessment and management, and identify the most critical piece of information you need from the daughter before transport.

Show answer

Metoprolol (a beta-blocker) suppresses the tachycardic response to hypovolemia, meaning her HR of 78 could be masking significant internal bleeding from a hip or pelvic fracture sustained in the fall—you cannot rely on heart rate elevation to identify shock. Lisinopril (an ACE inhibitor) may blunt her vasoconstrictive compensatory response, potentially leading to earlier hypotension with fluid loss. Warfarin (an anticoagulant) dramatically increases the risk of internal hemorrhage—even minor trauma can cause life-threatening bleeding, including subdural hematoma, which may have a delayed presentation of hours. Metformin (a diabetes medication) raises concern for hypoglycemia, especially if the patient missed meals after falling. The most critical information from the daughter is the patient's baseline mental status—whether her current orientation is normal or represents a change—because acute altered mental status in an anticoagulated patient who fell could indicate intracranial hemorrhage requiring emergent transport to a trauma center.

Question 4: APPLIED

You are called to a residence for a 28-year-old female at 38 weeks gestation who reports contractions every 2 minutes lasting 60–90 seconds. On examination, you observe crowning. The nearest hospital with a labor and delivery unit is 25 minutes away. Describe your immediate management priorities, your approach to field delivery, and your actions if the umbilical cord is found wrapped around the neonate's neck during delivery.

Show answer

With crowning present and contractions every 2 minutes, delivery is imminent and transport is not feasible. Your immediate priorities are: (1) prepare the OB kit, ensuring clean towels, clamps, sterile scissors, bulb syringe, and thermal management supplies are ready; (2) position the mother in a semi-recumbent or lithotomy position and ensure privacy; (3) do NOT attempt to delay delivery or push the baby back. During delivery, support the head as it emerges, checking for a nuchal cord. If the umbilical cord is wrapped around the neonate's neck, attempt to gently slip it over the head. If it is too tight to reduce, clamp the cord in two places and cut between the clamps before delivering the body. After delivery, dry and stimulate the newborn vigorously, assess breathing and heart rate, keep the baby warm (skin-to-skin on the mother's chest with blankets), and suction only if the airway is visibly obstructed. Clamp and cut the cord, monitor for placental delivery (do not pull on the cord), and assess the mother for postpartum hemorrhage. Then transport both patients to the nearest hospital with labor and delivery capabilities, performing fundal massage if excessive bleeding occurs.

Question 5: CRITICAL THINKING

A 4-year-old is found unresponsive by his parents. Upon your arrival, he is apneic with a heart rate of 40 bpm and cyanotic. The parents report he was playing with small toys before he was found. Develop a prioritized management plan that integrates pediatric airway anatomy considerations, the significance of his bradycardia, and the decision points that would alter your treatment algorithm. Address how this scenario would differ if the patient were a 75-year-old male found in the same condition.

Show answer

This 4-year-old is in respiratory arrest progressing to cardiac arrest, most likely from foreign body airway obstruction (FBAO) given the history of playing with small toys. Management priorities: (1) Open the airway using the jaw-thrust or head-tilt chin-lift in neutral position (not hyperextended—the pediatric airway is anterior and more easily occluded by overextension); (2) Look in the mouth—if a foreign body is visible, remove it with a finger sweep; if not visible, do NOT perform blind finger sweeps in children as the proportionally larger tongue can push the object deeper; (3) If the child is unresponsive with a pulse, begin rescue breathing at 1 breath every 3–5 seconds with a pediatric BVM; (4) His HR of 40 represents bradycardia likely secondary to hypoxia—in pediatrics, bradycardia is almost always caused by respiratory failure, so the priority is aggressive oxygenation and ventilation rather than pharmacological or electrical cardiac interventions; (5) If HR falls below 60 with signs of poor perfusion despite adequate ventilation, begin CPR (30:2 for single rescuer, 15:2 for two rescuers). The critical decision point is whether ventilation is effective—if BVM ventilation cannot move the chest, reposition the airway and consider direct laryngoscopy for foreign body visualization. In contrast, a 75-year-old found unresponsive, apneic, and bradycardic would more likely be experiencing a primary cardiac event (MI, complete heart block, or medication toxicity from beta-blockers or calcium channel blockers). The airway anatomy allows standard positioning. The treatment algorithm would still prioritize airway and ventilation, but the differential diagnosis would emphasize cardiac etiologies, and the EMT would need to apply the AED early, obtain a thorough medication history, and consider that CPR guidelines differ (30:2 ratio, adult compression depth of 2–2.4 inches versus 1/3 AP diameter in the child). The geriatric patient's fragile ribs increase the risk of rib fractures during CPR, but this should never deter resuscitative efforts.

SUMMARY

Lesson Summary

Summary

Effective prehospital care for special populations requires EMTs to move beyond the standard adult assessment model and apply population-specific clinical lenses. Pediatric patients demand the use of the Pediatric Assessment Triangle (PAT), Broselow tape for weight-based interventions, age-appropriate vital sign ranges, neutral airway positioning, and the recognition that bradycardia is an ominous pre-arrest sign. Geriatric patients require the GEMS diamond approach, thorough medication reconciliation to identify polypharmacy effects, heightened suspicion for atypical symptom presentations (painless MI, afebrile sepsis), and careful determination of baseline mental status to distinguish chronic from acute changes.

Obstetric patients represent a two-patient paradigm requiring awareness of pregnancy-induced physiological changes—increased blood volume creating physiological masking of hemorrhage, supine hypotensive syndrome managed by left lateral positioning, and the ability to recognize and manage preeclampsia and emergency field delivery. Across all populations, the EMT must select the appropriate specialty receiving facility and deliver comprehensive handoffs that include population-specific assessment findings, vital sign trends, and interventions performed.
