Asphyxia occurs when breathing is completely obstructed; which statement is true regarding its treatment?

• A. Remove breathing obstruction and give 100% O2
• B. Withhold oxygen to simulate breathing
• C. Apply wrist diuretic
• D. Stop oxygen delivery

Answer: (A)

When breathing is completely blocked, the priority is to clear the airway so air can reach the lungs, and then maximize oxygen delivery. Removing the obstruction and providing 100% oxygen directly addresses the loss of airflow and the resulting hypoxia, making it the best course of action. Giving oxygen supports tissue oxygenation as soon as the airway is open. Withholding oxygen would allow hypoxia to continue, giving a diuretic has no role here, and stopping oxygen delivery would worsen the situation. After the airway is cleared, continue ventilation support as needed and seek medical help.
