Answer :
Final answer:
Excessive ventilation after ROSC can cause Respiratory Alkalosis by removing too much carbon dioxide from the blood. Routinely over-oxygenating can lead to Oxygen Toxicity from too high levels of oxygen intake. Both these scenarios can be harmful and must be avoided
Explanation:
After Return of Spontaneous Circulation (ROSC), the immediate risk of excessive ventilation is causing Respiratory Alkalosis, a state where there is too little carbon dioxide in the blood due to hyperventilation. This can cause light-headedness, tingling sensations in the extremities, and unconsciousness in severe cases.
Moreover, the risk of routine over-oxygenation includes contributing to Oxygen Toxicity - a condition that occurs from breathing in too much oxygen, which can cause harm to cells.
In the case of hyperpnea, which is an increased depth and rate of ventilation due to an increase in oxygen demand, it does not significantly alter blood oxygen or carbon dioxide levels, but merely increases the depth and rate of ventilation to meet the demand of the cells. Excessive ventilation in this case can be harmful and unnecessary.
