What is the target EtCO2 level during cardiac arrest?

The target EtCO2 level during cardiac arrest is set to ensure optimal circulation and effective cardiopulmonary resuscitation (CPR). Maintaining EtCO2 levels greater than 10 mmHg indicates that there is some perfusion and circulation occurring, which is crucial in assessing the effectiveness of CPR. Levels above 20 mmHg are considered ideal because they suggest that significant circulation is being restored, reflecting improved cardiac output and better perfusion of the lungs.

Monitoring EtCO2 during CPR is a valuable tool as it can provide real-time feedback on the quality of chest compressions and the effectiveness of resuscitation efforts. Higher levels of EtCO2 correlate with better outcomes in patients experiencing cardiac arrest, as they signify effective gas exchange and better myocardial perfusion.

Setting the target at above 10 mmHg aligns with accepted guidelines and practices in emergency medical protocols, underscoring the importance of effective CPR and its physiological effects on the body during such critical situations.
