an intermittent alarm if the high or low pressure indicators are activated or if the optional
oxygen monitor detects lower than therapeutic levels of oxygen concentration. The alarm
remains on until you correct the alarm condition or you set the
I
/0 power switch to the “0”
position. Refer to Section 6.0 for a list of probable alarm causes.
2.3.1 Start Up/Battery Test
Each time the NewLife Intensity unit is turned on, an alarm should sound for
approximately five seconds.
The audio alarm must sound for approximately five seconds each time
the unit is turned to the “
I
” position to indicate the battery is in good
condition.
2.3.2 Power Failure Alarm Test
To test the power failure alarm, disconnect the unit from power, set the
l
/0 power
switch to the “
I
” position. This should activate the audio alarm. If it does not, refer
to the troubleshooting chart in Section 6.3 of this manual.
2.4
Oxygen Concentration Test and Specification
To ensure that the unit’s output of oxygen is within specification, you must perform a test
of the oxygen concentration. Test the unit upon delivery to a patient and at periodic
intervals. Equipment Providers need to establish and implement a protocol to check
oxygen concentration.
1.
If a humidifier bottle is used, disconnect it.
2.
Connect a calibrated oxygen concentration analyzer to the oxygen outlet.
3.
Verify that the product flow rate delivered by the unit matches the patient’s
prescription and does not exceed the capacity of the unit.
4.
Set the unit’s
l
/0 power switch to the “
I
” position. Allow approximately five
minutes for the oxygen concentration to stabilize. Take oxygen concentration
readings and verify levels are within specification at the liter flow being tested.
5.
Disconnect the oxygen analyzer, and reconnect the humidifier bottle (if used).
Do not measure oxygen concentration output after the product stream
passes through a humidifier bottle, or erroneous readings will result.
