Airway

Smoke inhalation with shallow breathing

After a house fire, a hoarse voice warns of airway burn and swelling, but rapid shallow respirations mean the patient is already failing to move enough air. High-flow oxygen by non-rebreather cannot replace lost tidal volume.

Assist ventilations with a bag-valve mask now; suction only if secretions or debris are present, and delay a full vital-sign set until airway and breathing are supported.
