Administer oxygen and support ventilation as needed. Hypoxemia in sepsis often stems from ventilation-perfusion mismatch or ARDS, requiring prompt oxygenation to prevent further organ dysfunction.

Immunocompromised patients (e.g., chemotherapy, transplant, HIV). Suppressed immunity allows infections to escalate quickly without typical symptoms, necessitating heightened suspicion and rapid assessment in prehospital settings.

Hypothermia or normal temperature despite serious infection. Impaired immune responses in these groups may blunt febrile reactions, so absence of fever does not rule out severe infection requiring urgent intervention.
