A patient is intubated and set up on VC-CMV. After stabilization and suctioning of the ET tube, the peak inspiratory pressure (PIP) is 25 cm H2O
The low pressure and high pressure alarms should be set at _____________ cm H2O and _____________ cm H2O, respectively.
a. 5; 35
b. 10; 30
c. 12; 40
d. 15; 35
ANS: D
The low pressure alarm should be set 5-10 cm H2O below the PIP, and the high pressure alarm should be set about 10 cm H2O above the PIP. Therefore, with a PIP of 25 cm H2O, the low pressure alarm should be set at 15-20 cm H2O and the high pressure alarm at 35 cm H2O.
