A patient-ventilator system check reveals the following information: peak inspiratory pressure (PIP)27 cm H₂O,positive end-expiratory pressure (PEEP)5 cm H₂O,plateau pressure (Pₚₗₐₜₑₐᵤ)14 cm H₂O,inspiratory time (Tɪ)0.75 second,and set frequency 20/minute.Calculate the mean airway pressure.
A) 6.75 cm H₂O
B) 7.75 cm H₂O
C) 11.75 cm H₂O
D) 12.37 cm H₂O

Quizplus · Accepted Answer

Total cycle time (TCT)= 60/frequency = 60/20 = 3 seconds.(P-macron)aw = $1/2$ [(PIP - PEEP)× (TI/TCT)] + PEEP = $1/2$ [(27 - 5)× (0.75/3)] + 5 = (22 × 0.25)+ 5 = $1/2$ 7.75 cm H₂O.
