After accounting for the compressed volume loss on a stable adult patient receiving vol-ume-controlled continuous mandatory ventilation at a preset volume of 500 ml, you still note a 150-ml difference between the expected and the actual delivered volume.

Which of the following is most likely causing this problem?
a. Gas absorption across the alveolar mem-brane
b. Increase in the respiratory quotient
c. Bronchopleural fistula or pneumothorax
d. Leak in the patient-ventilator system

Question 2

Which of the following is considered an acceptable tidal volume for mechanical ventilation?

a. 3 to 5 ml/kg
b. 5 to 7 ml/kg
c. 4 to 8 ml/kg
d. 8 to 10 ml/kg

Answer to Question 1

ANS: D
An additional factor that can cause a patient to receive less volume than the ventilator delivers is a leak.

Answer to Question 2

ANS: B
The currently accepted VT for mechanical ventilation in acute respiratory failure is 4 to 8 ml/kg predicted body weight (PBW).
