What does quantitative waveform capnography measure?

• A. Heart rate variability during CPR
• B. End-tidal CO2 to estimate tissue perfusion
• C. Oxygen saturation levels
• D. Blood pressure during resuscitation

Answer: (B)

Quantitative waveform capnography specifically measures the concentration of carbon dioxide (CO2) in exhaled air, referred to as end-tidal CO2. This measurement provides critical information about a patient’s respiratory status and can be used to estimate tissue perfusion. During resuscitation, monitoring the levels of end-tidal CO2 allows healthcare providers to assess the effectiveness of chest compressions and the overall circulation status. A higher end-tidal CO2 indicates better perfusion, while a low level may suggest inadequate chest compressions or other issues with circulation. This makes end-tidal CO2 a vital tool in monitoring patients during cardiac events and resuscitation efforts.
