When performing an initial pulmonary artery occlusion pressure (PAOP), what are the best nursing actions? (Select all that apply.)
a. Inflate the balloon for no more than 8 to 10 seconds while noting the waveform change.
b. Inflate the balloon with air, recording the volume necessary to obtain a reading.
c. Maintain the balloon in the inflated position for 8 hours following insertion.
d. Zero reference and level the air-fluid interface of the transducer at the level of the phlebostatic axis.
A, B, D
To obtain an accurate pulmonary artery occlusion pressure (PAOP), the transducer system should be zero referenced and leveled to ensure accurate readings, and the balloon should be inflated with enough air, for no more than 8 to 10 seconds until a change in waveform is noted. The volume of air necessary to inflate the balloon should be documented. Maintaining the balloon in the inflated position can lead to pulmonary infarction.
