Calculate the static compliance given the following clinical data: tidal volume 500 mL,peak inspiratory pressure (PIP)35 cm H₂O,plateau pressure (Pₚₗₐₜₑₐᵤ)25 cm H₂O,positive end-expiratory pressure (PEEP)12 cm H₂O,measured unintended positive end-expiratory pressure (auto-PEEP)3 cm H₂O,and tubing compliance (Cᴛ)2.5 mL/cm H₂O.
A) 17.5 mL/cm H₂O
B) 34 mL/cm H₂O
C) 36 mL/cm H₂O
D) 47.5 mL/cm H₂O

Quizplus · Accepted Answer

Static compliance = tidal volume (Vᴛ)- [(Pₚₗₐₜₑₐᵤ - PEEP)× Cᴛ]/(Pₚₗₐₜₑₐᵤ - PEEP)= 500 - [(25 - 15)× 2.5]/25 - 15 = (500 - 25)/10 = 47.5 mL/cm H₂O.
