What must be done to the airway when evaluating an injury?

When evaluating an airway during an injury, the primary concern is to ensure that it is open and clear for the individual to breathe. Opening the airway is crucial, especially in emergency situations where unconsciousness or injury may impede normal breathing. This can involve techniques like the head-tilt, chin-lift maneuver or a jaw-thrust maneuver, depending on the situation and any potential spinal injuries.

By opening the airway, you facilitate air passage to the lungs, which is essential for oxygenation and overall physiological function. This step is vital in protocols for first aid and emergency response, which emphasize the importance of maintaining an open airway to prevent potentially life-threatening situations. Assessing or blocking the airway, while important in certain contexts, does not prioritize the immediate need for ventilation and respiration.
