Answer :
Final answer:
The AHA highlights four negative consequences of excessive ventilation: decreased cardiac output, barotrauma, decreased venous return, and it becomes difficult to gauge the effectiveness of chest compressions.
Explanation:
The American Heart Association (AHA) emphasizes four negative consequences of excessive ventilation.
- Decreased cardiac output: Over-ventilating can lead to increased pressure in the chest cavity, which can hinder the heart's ability to pump blood effectively. It's vital to maintain a proper balance for optimal heart functionality.
- Barotrauma: This refers to injuries caused by increased air pressure, which can occur when a person is excessively ventilated.
- Decreased venous return: Over-ventilation can be the cause of ineffective circulation as it potentially decreases the return of blood to the heart.
- Impediment in gauging the effectiveness of chest compressions: Over-ventilation during CPR can make it challenging to monitor the effectiveness of chest compressions as the chest does not have the opportunity to fully reexpand.
