Answer:
Each ventilation should last about 1 second. This allows for adequate chest rise, ensuring the lungs are properly inflated without causing injury from over-inflation.
Explanation:
In CPR (cardiopulmonary resuscitation), providing ventilation involves giving breaths to the patient. Each breath should last about 1 second to ensure the lungs are adequately inflated, which helps oxygenate the blood. If breaths are given too quickly or forcefully, it can cause complications such as air entering the stomach (gastric inflation) or lung injury. Proper timing and volume of each ventilation are crucial for effective resuscitation and minimizing potential harm.
