Chapter 4 - Operation and Care

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.

Controlling Oxygen There is no oxygen pressure adjustment in the Intensive Care Unit. Pressure To increase or decrease oxygen pressure to the Intensive Care Unit,

adjust the regulator at the oxygen supply source.

Controlling Oxygen The oxygen flow rate is controlled by a flow rate meter and adjust- Flow Rate ment knob (Figure 59) on the front of the electronics compartment.

The meter is calibrated from 1/2 to 15 lpm (liters-per-minute).

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.
