During resuscitation, which intervention specifically involves warming the inhaled gas?

• A. Increase heat in the room
• B. Administer humidified and warm O2 (41C) in ET
• C. Monitor temperature (core if possible)
• D. Remove all wet clothing

Answer: (B)

Warming and humidifying the inhaled gas acts to protect the airway as ventilation is ongoing. When oxygen is delivered through the endotracheal tube, heating it to near body temperature (around 41°C) and adding humidity prevents drying of the airway mucosa, reduces thick secretions, and helps maintain mucociliary function. This improves comfort, airway patency, and gas exchange during resuscitation. The other actions—increasing room heat, monitoring temperature, or removing wet clothing—address general warmth or assessment but do not specifically condition the inhaled gas for the airway and lungs.
