Question

A 58-year-old man is intubated with a 8.0 mm ID endotracheal tube. The ventilator displays a peak inspiratory pressure of 35 cmH2O and a plateau pressure of 22 cmH2O. PEEP is 8 cmH2O. What is the airway resistance?

Accepted Answer

Cannot be calculated without knowing the inspiratory flow rate

Answer

5 cmH2O/L/s

Answer

13 cmH2O/L/s - calculated from (Peak - Plateau) / Flow

Answer

14 cmH2O/L/s

Answer

22 cmH2O/L/s
