Rcp 160 Midterm Study Guide With Complete Solution

Calculate the tubing compliance (CT) when the measured volume is 150 mL and the static pressure is 53 cm H2O. Question options: -0.003 mL/cm H2O -0.35 cm H2O/mL -2.8 mL/cm H2O -7.95cm H2O/mL - CORRECT ANSWER 2.8 mL/cm H2O Feedback: Calculate tubing compliance (CT) by dividing measured volume by measured static pressure. 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 peak pressure reached during volume delivery is 28 cm H2O. How much volume is lost in the ventilator tubing? - 147 mL - 168 mL - CORRECT ANSWER 60 mL Feedback:Calculate tubing compliance (CT) by dividing measured volume by measured static pressure. The amount of volume lost to the circuit equals the pressure reached during a tidal volume (VT) delivery multiplied by the CT factor. Calculate the average tidal volume for a patient who has a minute ventilation of 10 L/min with a respiratory rate (RR) of 12 bpm. - 1000 mL - 1200 mL - CORRECT ANSWER -833 mL feedback- Minute ventilation equals respiratory rate multiplied by tidal volume (VT). Therefore, tidal volume equals minute ventilation divided by respiratory rate. Calculate the inspiratory time (TI) when a ventilator is set at a tidal volume (VT) of 800 mL and a constant flow rate of 40 L/min. Question options: - 1:1.1 1 - 13 mL - 60 mL - 120 mL - 833 m
