When initially setting up a ventilator,the plateau pressure (P_Plateau)is measured at 68 cm H₂O with a set volume of 200 mL.After applying the ventilator to the patient,the average peak pressure reached during volume delivery is 22 cm H₂O.How much volume is lost in the ventilator tubing?

Question

Quizplus · Accepted Answer

Calculate tubing compliance (C_T)by dividing measured volume by measured static pressure.The amount of volume lost to the circuit equals the pressure reached during a tidal volume (V_T)delivery multiplied by the C_T factor.
