A 90kg patient was placed on a mechanical ventilator following a major thoracic surgery. A ...

1. Calculate the static compliance (CS), in mL/cm H2O, when PIP is 47 cm H2O, plateau pressure (Pplateau) is 27 cm H2O, baseline pressure is 10 cm H2O, and exhaled tidal volume (VT) is 725 mL. a. 43 CS b. 36 CS c. 20 CS d. 0.065 CS - ️️A. Cs = Vt/(Pplat - PeeP) Cs = 725 / (27-10), Cs=725/17, 42.64=725/17 2. Air accidently trapped in the lungs due to mechanical ventilation is known as which of the following? a. Plateau pressure (Pplateau) b. Functional residual capacity (FRC) c. E...

. Calculate the tubing compliance (CT) when the measured volume is 150 mL and the static pressure is 53 cm H2O. a. 0.003 mL/cm H2O b. 0.35 cm H2O/mL c. 2.8 mL/cm H2O d. 7.95cm H2O/mL → -:- C 2.8 mL/cm H2O → Calculate tubing compliance (CT) by dividing measured volume by measured static pressure. 2. When initially setting up a ventilator the plateau pressure (PPlateau) is measured at 47 cm H2O with a set volume of 100 mL. After applying the ventilator to the patient, the average ...
