The O
cell gives an output voltage proportional to the

partial pressure of oxygen inside the Inspiratory pipe.
At constant ambient pressure this output is
proportional to the O
each O
cell, the output signal will stay at a fairly
2
constant level usually within 10–17 mV in normal air
and at standard barometric pressure during the life
time of the cell. The cell should be replaced when the
output level has started to decrease. In this situation,
repeated calibration (i. e. Pre-use check) of the O
concentration is required. The life time of the cell is
affected by the O
concentration (at the cell) in % and expected cell life
time in hours the following applies at 25
O
Conc. x Expected cell life = 500 000% hours.

The O
cell is automatically calibrated each time a Pre-
