For a near-drowning victim on mechanical ventilation who is hypercapnic, what should be done to ventilator settings?

For a near-drowning victim on mechanical ventilation who is hypercapnic, the appropriate action is to decrease the frequency of ventilation. Hypercapnia, which refers to elevated levels of carbon dioxide (CO2) in the blood, indicates that the patient's ventilation is insufficient for clearing CO2 effectively.

By reducing the frequency, you allow for more time for each breath, which can help with better gas exchange and a more effective elimination of CO2 during exhalation. When the ventilator settings are adjusted to decrease the rate, it often results in longer inspiratory and expiratory times, reducing the likelihood of air-trapping and ensuring that the lungs have adequate time to clear CO2.

This adjustment is critical, especially in a near-drowning case where the lungs may be compromised. Ensuring the patient can effectively ventilate helps in managing hypercapnia and promoting better overall lung function.
