The therapist is providing volume controlled-continuous mandatory ventilation (VC-CMV) to a patient using the following settings: PIP 40 cm H2O Pplateau 25 cm H2O PEEP 10 cm H2O VT 700 ml Tubing compliance factor 3 ml/cm H2O Based on this information, calculate the volume compressed in the ventilator breathing circuit at the end of inspiration
A. 120 ml
B. 90 ml
C. 75 ml
D. 45 ml
?ANS: B
A. Incorrect response: See explanation B.
B. Correct response: When the tubing compliance (CT) is known, the formula for calculating the compressible volume is as follows:
(PIP – PEEP) CT = Vcompressed
(40 cm H2O – 10 cm H2O) 3 ml/cm H2O = 90 ml
C. Incorrect response: See explanation B.
