What ventilation rate should be used for stroke patients who are apneic or inadequately ventilating?

The main idea is to ventilate stroke patients who aren’t breathing well at a rate that maintains oxygen delivery without triggering hyperventilation. In acute stroke, keeping cerebral perfusion where it’s needed is crucial, and blowing off too much CO2 with rapid ventilation can cause cerebral vasoconstriction and reduce blood flow to the brain. That’s why a moderate rate—about 10 to 12 breaths per minute—is used. It provides adequate ventilation to prevent hypoxia but avoids the problems that come with forcing breaths too quickly. Breathing too slowly, around 6 to 8 per minute, risks hypoxemia and buildup of CO2, which can worsen brain injury. Breathing too quickly, around 12 to 14 per minute, risks hyperventilation, increased intrathoracic pressure, and decreased venous return, which can also compromise cerebral perfusion. Deliver each breath with enough volume to see chest rise (roughly a normal tidal volume) and adjust as needed based on the patient’s color, pulse oximetry, and overall condition.
