This guide is for the Philips Respironics V200 / Espirit Ventilator, Part Number 580-1000-02 H. This pressure accuracy test verifies the accuracy of the inhalation and exhalation pressure transducers. This test requires a patient circuit and analyzer. Information in this guide was sourced from the Service Manual in chapter 8.5.5 on pages 8-21 and 8-22. For further information on the Inhalation/Exhalation Pressure Transducer and and Exhalation Valve, please see chapter 5.8.16 on page 5-25.

-
-
Put ventilator into diagnostic mode (page 8-21 in Service Manual):
-
Begin with ventilator powered off.
-
Press ALARM RESET and 100% O2 keys located on the right of the front panel key section (as shown in Figure 8-2) for approximately 5 seconds while turning ventilator power on.
-
Touch OK to enter diagnostic mode.
-
-
-
Connect a patient circuit and analyzer to the ventilator as shown in Figure 8-19 (page 8-21 in Service Manual).
-
-
-
Set the analyzer’s function to read cmH2O by setting pressure range to measure at least 120 cmH2O (page 8-21 in Service Manual).
-
-
-
On the Hardware screen, touch safety (white background, as shown in figure 8-18 on page 8-21 of Service Manual) to energize the safety solenoid.
-
-
-
On the Hardware screen, touch Exhalation (blue background, seen in Figure 8-18, found on page 8-21 of the Service Manual).
-
-
-
On the Hardware screen, touch Air (blue background, seen in the top left area of Figure 8-18 on page 8-21 of the Service Manual).
-
-
-
On the Hardware screen, touch Exhalation and adjust the steps until the analyzer pressure reads 100 +- 5 cmH2O (95 to 105 cmH2O).
-
Information found on page 8-21 of the Service Manual.
-
-
-
Check that the Inhalation Pressure and Exhalation Pressure displays on the Hardware screen read within ± 10% of the analyzer display.
-
Example: If the analyzer’s display reads 98.7 cmH2O, 10% of the display is 9.87 cmH2O, and ± 10% of the analyzer display would be 88.83 to 108.57 cmH2O (-10% = 98.7 - 9.87 = 88.83 cmH2O, and + 10% = 98.7 + 9.87 = 108.57 cmH2O).
-
Information found of page 8-21 of the Service Manual.
-
If Inhalation/Exhalation pressure readings are out of range at 100 cmH2O, recommended troubleshooting and repair is as follows and can be found in the Service Manual in Chapter 8.7.5 page 8-44:
- Check for leaks at circuit connections, test lung, filters, etc.
- Check for kinked or cut tubing from inhalation module to SOL4, and from SOL4 to sensor PCB.
- Check for kinked or cut tubing from exhalation pressure tap to SOL3, and from SOL3 to sensor PCB.
- Check for leaks at the oxygen sensor/oxygen valve connection.
- Replace the sensor PCB.
- Replace the 3-station solenoid.
