Capnography plays a crucial role in assessing the effectiveness of ventilation during resuscitation. It measures the concentration of carbon dioxide (CO2) in exhaled air, providing immediate feedback on the patient's ventilatory status. During resuscitation efforts, maintaining adequate ventilation is essential for ensuring that the tissues are receiving enough oxygen and that carbon dioxide is being effectively expelled from the body.

A key application of capnography in this context is its ability to indicate how well the airway is secure and whether the chest compressions are generating effective perfusion. A sudden change in the waveform or a drop in end-tidal CO2 levels can signify that ventilation is inadequate or that the quality of chest compressions might be poor. Consequently, it enhances the resuscitation team's ability to make real-time adjustments to their techniques, ensuring that their actions are helping to stabilize the patient. This real-time monitoring is invaluable during critical situations where rapid assessments can dictate the success of resuscitation efforts.

Other options relate to different aspects of patient assessment and intervention but do not address the specific monitoring of ventilation.
