Answer :
Final answer:
Excessive artificial ventilation during CPR can cause barotrauma, decreased cardiac output, and hyperventilation leading to respiratory alkalosis.
Explanation:
Excessive artificial ventilation during CPR can lead to a number of potential adverse effects. One primary issue is that it can cause an effect called barotrauma. Barotrauma is damage caused by significant changes in air pressure, which can lead to conditions such as pneumothorax (collapsed lung), or gastric inflation, which ultimately can lead to vomiting and aspiration. Excessive ventilation can also reduce cardiac output because it increases thoracic pressure, reducing the ability of blood to return to the heart and decrease coronary perfusion pressure.
Another potential problem of excessive artificial ventilation is that it can cause hyperventilation. Hyperventilation decreases the amount of carbon dioxide in the blood. Since the amount of carbon dioxide in the blood affects blood pH levels, reducing carbon dioxide levels too much can cause the blood to become too alkaline, leading to a condition called respiratory alkalosis.
