Which of the following parameters are displayed on the user interface of the Covidien PB 840?

1. Expired minute volume
2. Peak inspiratory pressure
3. Rapid shallow breathing index
4. Static compliance
5. Intrinsic positive end-expiratory pressure
a. 1 and 3 c. 1, 2, 4, and 5
b. 2, 3, and 5 d. 1, 2, 3, 4, and 5

Question 2

Which of the following statements best describes the volume support mode on the Covidien PB 840?

a. The ventilator ensures that a minimum of 80 of the set tidal volume is delivered with each breath.
b. The ventilator delivers volume-targeted breaths with each inspiratory effort.
c. The ventilator delivers pressure-limited breaths; the pressure is adjusted to ensure that the set tidal volume is delivered.
d. The ventilator delivers pressure-targeted breaths, and the respiratory rate is adjust-ed to ensure delivery of a preset minute volume.

Answer to Question 1

ANS: D
The display on the user interface of the Covidien PB 840 includes the expired minute volume, peak inspiratory pressure, rapid shallow breathing index, static compliance, and intrinsic positive end-expiratory pressure.

Answer to Question 2

ANS: C
Volume support is pressure support ventilation with a volume target. In volume support, breaths are patient triggered (pressure or flow), pressure limited, and flow cycled. The ventilator auto-matically adjusts the pressure limit to achieve the set tidal volume.
