Which of the following statements concerning the CareFusion Bird Partner IIi monitor is true?
1. This device uses a vortex ultrasonic device to measure flow.
2. To prevent obstructions, 12 mL/min of gas is passed through the pressure line.
3. This device can measure artificial airway leak only with the use of the infant sensor.
4. Placement of the pediatric and infant sensors is the same in the ventilator tubing.
a. 1 and 2 c. 3 and 4
b. 2 and 3 d. 1 and 4
ANS: B
The gas inlet on the back of the ventilator connects to a 50-psig source and is used to inject 12 mL/min of gas through the pressure line to prevent obstructions within the line and to prevent water from entering the differential pressure transducer. By pressing and holding the "CONT V" button on the touch pad, the clinician enables real-time flow through the infant sensor to be dis-played. The clinician can use the baseline leak or the flow displayed between breaths to deter-mine the best trigger sensitivity setting and to prevent auto-triggering. This device uses a varia-ble-orifice differential pressure transducer.
