Introduction
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 [https://www.ifixit.com/Document/uHU5MIrC51dBUcNN/Philips+Respironics+V200+Espri.pdf|Service Manual (revision H)] 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.
Conclusion
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 [https://www.ifixit.com/Document/uHU5MIrC51dBUcNN/Philips+Respironics+V200+Espri.pdf|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.
