Final answer:
Measuring waveform capnography (PETCO2) during CPR is important to assess the effectiveness of chest compressions and the person's respiratory status.
Step-by-step explanation:
During CPR, measuring waveform capnography (PETCO2) is important because it provides valuable information about a person's respiratory status and the effectiveness of chest compressions. PETCO2 stands for End-tidal carbon dioxide, which is a measurement of the partial pressure or concentration of carbon dioxide in exhaled breath.
By measuring PETCO2 during CPR, healthcare providers can assess the quality of chest compressions. When chest compressions are effective, they generate blood flow and carbon dioxide is transported to the lungs for exhalation. As a result, PETCO2 levels increase, indicating that the person is receiving sufficient CPR.
On the other hand, if chest compressions are inadequate, PETCO2 levels will be low or undetectable. This indicates poor blood flow and suggests that adjustments need to be made to improve the effectiveness of CPR.
