Ventilation During Cardiopulmonary Resuscitation  

• 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.
