Abstract:This paper introduced the working principle of MAQUET SERVO series ventilator and expounded the failures of
barometer, oxygen sensor and flow sensor caused by “technical error 40001” “technical error in exhalation box” and “technical
error 38” “technical error 3” when starting up. By analyzing the electric and gas circuit, find out the cause of the failure, determine
the specific maintenance scheme combined with the corresponding technical means, and finally eliminate the fault by replacing the
corresponding temperature compensation resistor, EEPROM burning and replacing the pressure sensor. This paper analyzed the
common technical failures in the maintenance of MAQUET SERVO series ventilators, and summarized the causes and solutions of
the faults, which can be used as a reference for the majority of medical engineers.
