Abstract:Objective The working principle of the pneumatic circuit of Feiping ventilator and the maintenance and troubleshooting
method of 2 cases of pressure failure were described in detail, so as to provide reference for medical workers to know about
the ventilator of Feiping and to repair similar faults. Methods The method of simplicity before difficulty was followed,
the possible reasons were analyzed, and the method of troubleshooting and maintenance was provided. Results The working
principle and material parts of air circuit of Fabian ventilator were fully understood. The faults of air and oxygen supply
could not be detected by the ventilator, no pressure, no nor- mal airflow were successfully solved. Conclusion The two cases of
fault maintenance introduced in the present study are all achieved parts level maintenance, which can save a lot of funds
and shorten the maintenance cycle compared to plate level maintenance.
