Which of the following indicates an increase in airway resistance in a patient receiving mechanical ventilation with a constant tidal volume?
A) Increased peak inspiratory pressure (PIP) and transairway pressure (Pᴛᴀ)
B) Increased static compliance
C) Increased plateau pressure (Pₚₗₐₜₑₐᵤ) and stable PIP
D) Decreased dynamic compliance

Question

Quizplus · Accepted Answer

Airway resistance can be estimated for a ventilated patient using transairway pressure (Pᴛᴀ).When peak inspiratory pressure (PIP)increases and plateau pressure (Pₚₗₐₜₑₐᵤ)remains relatively unchanged,there is an increase in Pᴛᴀ.An increased Pₚₗₐₜₑₐᵤ and a stable PIP indicate a decrease in static compliance.
