When performing CPR on an adult patient with an endotracheal tube (ET) in place, how should ventilations be delivered?

Delivering ventilations to an adult patient with an endotracheal tube in place should occur every 6 seconds. This interval is based on current guidelines for airway management and ventilation during CPR. The rationale for this timing is to ensure adequate oxygenation without causing hyperventilation, which can decrease blood flow and cause complications.

When ventilating a patient with an ET tube, the aim is to provide effective breaths while allowing enough time for the person’s lungs to expel carbon dioxide between each ventilation. Ventilations delivered too frequently can lead to increased intrathoracic pressure and reduced venous return to the heart, negatively impacting cardiac output. Thus, the recommended rate of one breath every 6 seconds allows for optimal ventilation while minimizing the risks associated with hyperventilation.

Understanding these principles is crucial for providing effective care during resuscitation efforts when an advanced airway is in place.
