Answer :
Final answer:
Excessive ventilation after cardiac arrest can lead to harmful physiological effects such as decreased cardiac output, reduced cerebral and coronary perfusion, and exacerbation neurological injury.
Explanation:
The immediate danger of excessive ventilation during the post-cardiac arrest period for patients who achieve ROSC (Return of Spontaneous Circulation) is that it can lead to significant negative physiological effects. This is primarily because excessive ventilation can cause an increase in intrathoracic pressure which leads to a decrease in venous return, in turn reducing cardiac output and eventually cerebral and coronary perfusion. It can also lead to respiratory alkalosis by blowing off too much carbon dioxide, which can exacerbate neurological injury. These complications may ultimately hinder patient recovery.
