Which device could you use to provide feedback on the quality of CPR?

1. Capnography

2. A visual assessment

3. An AED unit

4. A stethoscope

The correct answer is: Capnography

Capnography is the most effective device for providing real-time feedback on the quality of cardiopulmonary resuscitation (CPR). This technology measures the concentration of carbon dioxide in exhaled air, providing critical information about the effectiveness of chest compressions and overall ventilation during resuscitation efforts. A consistent capnography reading indicates adequate perfusion and effective CPR, while sudden drops can signal deterioration or improper technique. In contrast, visual assessment, although useful in gauging certain aspects of CPR, lacks the quantitative data that capnography provides. It relies on subjective observation rather than objective measurements. An AED unit primarily functions to analyze the heart's rhythm and deliver shocks as necessary but doesn't directly assess CPR quality. A stethoscope is mainly used for auscultation and can help confirm certain sounds, but it doesn't give immediate feedback regarding the effectiveness of compressions or ventilation in real-time. Thus, capnography stands out as a specialized tool in monitoring the kinetics of CPR, ensuring that rescuers can adjust their techniques promptly to improve patient outcomes.
