Oxygen Supply
Pressure Alarm
The oxygen supply pressure alarm is activated when the oxygen supply
pressure in the system falls below approximately 37 psi. When the alarm
is activated, the red O
2
SUPPLY PRESSURE LED on the main switch
panel lights. In addition, the Caution message LO O

SUPPLY appears
on the central alarm display and an intermittent audible alarm sounds.
Depending on the anesthesia machine’s configuration, a 7-second whistle
may also sound.
NOTE: When one source of oxygen pressure (either pipeline or
reserve cylinders) fails, but the other source is able to
maintain proper pressure within the machine’s oxygen supply
lines, the oxygen supply pressure alarm is not activated.
