Cardiopulmonary resuscitations are often highly stressful and chaotic situations. As a result, it is no surprise that ventilation rates can be as high as 60 breaths per minute.
Hyperventilation during cardiopulmonary resuscitation can increase intrathoracic pressure, impair venous return, decrease coronary perfusion pressure, and ultimately decrease survival.
It is imperative that the team leader pay close attention to ventilation and ensure that approximately 8 to 10 breaths per minute are delivered.
Once ROSC is achieved, the respiratory rate should be adjusted to maintain a PaCO2 between 40 and 45 mm Hg.
