A recruitment maneuver (RM)is being performed on a patient receiving mechanical ventilation with PCV.During the maneuver the mode remains in PCV,rate = 10/min,I:E = 1:2,and PIP = 35 cm H₂O.The following information is documented during the RM:
$\begin{array} { | l | l | l | l | l | l | l | l | l | l | }
\hline \text { Time } & 0800 & 0805 & 0810 & 0815 & 0820 & 0825 & 0830 & 0835 & 0840 \
\hline \text { PEEP } & 10 & 15 & 20 & 25 & 30 & 25 & 20 & 15 & 10 \
\hline \begin{array} { l }
\text { Static } \
\text { Eampliance }
\end{array} & 24 & 29 & 34 & 25 & 22 & 27 & 31 & 36 & 32 \
\hline \text { EP } & 126 / 68 & 124 / 66 & 118 / 58 & 110 / 55 & 106 / 58 & 112 / 60 & 118 / 62 & 115 / 60 & 117 / 62 \
\hline \text { HR } & 108 & 108 & 105 & 100 & 100 & 102 & 105 & 106 & 105 \
\hline
\end{array}$
After the RM,the lungs are reinflated.At what level should the PEEP be set for this patient?
A) 12 cm H₂O
B) 17 cm H₂O
C) 22 cm H₂O
D) 27 cm H₂O

This is the PCV with increased PEEP recruitment technique.The point of decreased compliance on deflation represents the UIPd of the lungs.Once the lungs have been reinflated to allow reopening of lung units,PEEP is decreased until a pressure 2 cm H₂O above the UIPd is obtained.For this patient,that would be 12 cm H₂O.
