Generally, the service life of the oxygen battery is about 1 ~ 3 years
The oxygen battery is generally located between the patient's inspiratory end and the air oxygen mixer
For example, the air circuit system of MAQUET servo I machine: air and oxygen enter the two gas modules respectively, and are sent to the mixing chamber after being calculated according to the set moisture volume, pressure level and oxygen concentration
There is a mixing valve in the mixing chamber to stir the air flow
The air and oxygen are fully mixed and sent out after the actual oxygen concentration is monitored by the oxygen battery
Oxygen battery is only used for terminal monitoring in the machine, which has nothing to do with oxygen concentration control
2
Oxygen battery performance test (1) judge the failure of oxygen battery and observe the oxygen concentration monitoring
If the measured value deviates greatly from the set value, first check the oxygen source to see whether the oxygen pressure (0
24 ~ 0
6MPa, generally about 0
4MPa), flow (generally 120L / min) and oxygen concentration are normal
In addition, consider whether the air oxygen mixer is normal and eliminate the above possibilities, If the deviation between the measured value of oxygen concentration and the set value exceeds 10% for at least 30s, it can be judged that the oxygen battery has failed
