SSCI recommends an intake pressure of 10 to
20 psi with a flow rate of 15 lpm. Your experience
may indicate that a greater or lower pressure and/
or flow rate are desirable.
To increase the flow rate, turn the adjustment knob
clockwise. To reduce the flow rate, turn the knob
counter-clockwise. Take your readings from the
center of the ball in the transparent, graduated tube
on top the meter.
If the oxygen system experiences a minor, transient fault and then
corrects itself, the alarm may sound briefly and then stop. In this
case, it is not necessary to shut down the unit and you may continue
normal operations. If this happens frequently, however, check the
oxygen system and try to locate and correct the problem.
The alarm system includes a time delay to minimize alarms due to
minor, transient faults. For more information, refer to Setting the
Time Delay Relay on Page 59.
There is no oxygen pressure adjustment in the Intensive Care Unit.
To increase or decrease oxygen pressure to the Intensive Care Unit,
adjust the regulator at the oxygen supply source.
The oxygen flow rate is controlled by a flow rate meter and adjust-
ment knob (Figure 59) on the front of the electronics compartment.
The meter is calibrated from 1/2 to 15 lpm (liters-per-minute).
