During resuscitation, how often should you ventilate a patient who has achieved ROSC but remains unresponsive?

During resuscitation, once a patient has achieved return of spontaneous circulation (ROSC) but remains unresponsive, it is essential to provide adequate ventilation to support their breathing until they regain consciousness. The correct practice is to ventilate the patient once every six seconds. This rate allows for 10 breaths per minute, which is appropriate in such scenarios, ensuring that the patient receives sufficient oxygenation without compromising their hemodynamic stability.

Ventilating too infrequently could lead to hypoxia, while ventilating too frequently may result in hyperventilation and subsequent complications, such as decreased cardiac output or increased intracranial pressure. Thus, the six-second interval strikes a balance that supports effective oxygenation.

In comparison, the alternative choices either prescribe an inappropriate ventilation rate or associate ventilation with chest compressions, which is not the protocol established for a patient in ROSC. Adhering to the rate of every six seconds ensures that the patient receives the necessary respiratory support needed while they remain unresponsive.
