➡️ Question
During the ventilator check of an adult patient who weighs 77 kg, you note the following settings:
Exhaled tidal volume 550 mL
PIP 30 cmH2O
High pressure limit 65 cmH2O
Low pressure alarm 20 cmH2O
Low tidal volume alarm 500 mL
Which of the following changes should be made at this time?
A. Increase the set tidal volume to 700 mL
B. Increase the low tidal volume alarm to 535 mL
C. Decrease the high pressure limit to 40-45 cmH2O
D. Decrease the low pressure alarm to 10 cmH2O

Do you know the answer? If not, no worries. Let break it down.

To answer this one correctly, you needed to have a basic understanding of ventilator settings and alarms. This is definitely a topic that you should spend some time on when preparing for the TMC Exam. For this patient, all of the settings are acceptable except for one. The tidal volume, PIP, low pressure alam, and low tidal volume alarm all appear to be set appropriately.

A high pressure limit of 65 cmH2O, on the other hand, is way too high for this patient. As a general rule of thumb, the high pressure limit should be set 10-15 cmH2O above the PIP. Otherwise, the patient has an increased risk of barotrauma or lung injury if too much pressure is applied to the lungs. This patient's PIP is 30 cmH2O, which means the high pressure limit should be set between 40-45 cmH2O.
