Working principle and function of the ventilator oxygen battery:
The ventilator oxygen battery, also known as an oxygen sensor,
oxygen concentration sensor, or oxygen probe; the oxygen battery is
generally located at the patient's inhalation end and between the
air-oxygen mixture device [1]. The oxygen battery in the ventilator
only performs final monitoring, using electrochemical principles,
mainly for measuring the oxygen concentration of the mixed gas, and
is not related to oxygen concentration control. The measurement
range is 0% to 100%, and under constant pressure and constant
temperature conditions, the voltage value generated by the oxygen
battery is proportional to the oxygen concentration.
Judgment of oxygen battery failure and performance testing:
The judgment of oxygen battery failure can be directly observed
from the oxygen concentration monitoring situation. When the
measured oxygen concentration value deviates significantly from the
set oxygen concentration value, the machine will issue an alarm
prompt.
Oxygen battery usage time:
The output voltage of each oxygen battery is basically stable
throughout its lifespan. Generally, the working lifespan of an
oxygen battery is usually only one to two years, and high-quality
ones can be used for three years or more. The lifespan of the
oxygen battery will change due to the actual operating environment.
For example, using it in a high-oxygen concentration or
high-temperature environment will shorten its lifespan.
