10. Select these ventilator settings: Peak Flow = 140 LPM, Tidal Volume =
2500 mL. After six breaths the analyzer should read 2250 to 2750
mL.
11. Change the flow pattern to Square. After six breaths the analyzer
should read 2250 to 2750 mL.
12. Set the analyzer’s volume range for 3 L oxygen. Zero the analyzer
during exhalation.
13. Change the O
2
setting to 100%. After six breaths the analyzer should
read 2250 to 2750 mL.
14. Change the flow pattern to Ramp. After six breaths the analyzer should
read 2250 to 2750 mL.
15. Select these ventilator settings: Peak Flow = 60 LPM, Tidal Volume =
1000 mL. After six breaths the analyzer should read 900 to 1100 mL.
16. Change the flow pattern to Square. After six breaths the analyzer
should read 900 to 1100 mL.
17. Select these ventilator settings: Tidal Volume = 500 mL, Peak Flow =
30 LPM. After six breaths the analyzer should read 450 to 550 mL.
18. Change the flow pattern to Ramp. After six breaths the analyzer should
read 450 to 550 mL.
19. Change the Tidal Volume to 250 mL. After six breaths the analyzer
should read 225 to 275 mL.
20. Change the flow pattern to Square. After five breaths the analyzer
should read 225 to 275 mL.
21. The gas volume accuracy test is complete.
Oxygen Accuracy (Test 10)
The oxygen accuracy test verifies the accuracy of the oxygen percentage
delivered to the patient.
1. Calibrate the external oxygen monitor.
2. Remove the inspiratory bacteria filter from the ventilator.
3. Connect the external oxygen monitor in series with the ventilator
oxygen sensor (Figure 8-25).
