What should be monitored to assess the effectiveness of ventilation during CPR?

Monitoring capnography readings is crucial in assessing the effectiveness of ventilation during CPR. Capnography measures the concentration of carbon dioxide in exhaled air, providing real-time feedback on the effectiveness of chest compressions and the overall ventilation process.

In a properly ventilated patient, the end-tidal carbon dioxide (ETCO2) levels should reflect adequate blood flow and lung function. During CPR, higher ETCO2 readings are indicative of effective compressions and improved circulation. Conversely, low or varying ETCO2 levels can signal poor ventilation or inadequate perfusion, guiding rescuers to adjust their technique.

While skin color and temperature, heart rate and blood pressure, and neurological response are all important parameters to monitor in a clinical setting, they do not provide specific and immediate feedback on ventilation efficacy during CPR like capnography does. This makes capnography an essential tool for confirming that CPR is effectively restoring some level of circulatory and respiratory function.
