A patient-ventilator system check reveals the following information: peak inspiratory pressure (PIP)32 cm H₂O,positive end-expiratory pressure (PEEP)12 cm H₂O,plateau pressure (Pₚₗₐₜₑₐᵤ)20 cm H₂O,inspiratory time (Tɪ)1 second,and set frequency 12/min.Calculate the mean airway pressure.
A) 4 cm H₂O
B) 8 cm H₂O
C) 12 cm H₂O
D) 14 cm H₂O

Total cycle time (TCT)= 60/frequency = 60/12 = 5.(P-macron)aw = $1/2$ [(PIP - PEEP)× (TI/TCT)] + PEEP = $1/2$ [(32 - 12)× (1/5)] + 12 = $1/2$(20 × 0.2)+ 12 = 14 cm H₂O.
