Question

what is the main determinant of end - tidal carbon dioxide (etco₂) measurement during cpr? choose the correct answer tidal volume blood delivery to the lungs alveolar membrane permeability assisted ventilation rate

Explanation:

End - tidal carbon dioxide (ETCO₂) during CPR mainly depends on the amount of carbon - dioxide brought to the lungs by the blood. Tidal volume, alveolar membrane permeability, and assisted ventilation rate have less direct and major impact compared to blood delivery to the lungs during CPR.

Answer:

Blood delivery to the lungs
