Which of the following values is not measured directly?
A) FEV₁
B) Airway resistance (Raw)
C) Peak expiratory flows
D) Maximum inspiratory pressure

Question

Quizplus · Accepted Answer

FEV₁ and peak expiratory flows are routine measurements during spirometry.Maximum inspiratory pressure is a common airway pressure measurement made on spontaneously breathing patients.Raw is calculated by subtracting plateau pressure (Pₚₗₐₜₑₐᵤ)from peak inspiratory pressure and dividing the resultant pressure by the airflow.
