7.1 OPERATING PRINCIPALS & ESSENTIAL PERFORMANCE
This device works by separating oxygen from air using a pressure swing adsorption (PSA) process. Normal air
consists of 21% oxygen; this device increases the amount of oxygen up to 96% by removing the nitrogen and con-
centrating the output of oxygen. To accomplish this, air is pulled into the device through a small air compressor,
nitrogen is separated from the oxygen and finally, the oxygen is collected and delivered to the patient on
each breath.
Because the oxygen you breathe comes from your immediate environment, it is very important to keep your device
clean. Although there are many filters built into the device, exposing your device to dirty and dusty environments
will reduce the life of the filters causing them to need to be replaced more often.
The device maintains the following as essential performance requirements without the need for recurrent testing:
(1) Alarm condition when the delivery of oxygen, in both normal and single fault conditions, is not within the perfor-
mance levels as indicated in this manual. (2) Technical alarm condition when there is a power supply failure.
(3) Technical alarm condition when the battery nears depletion. (4) Technical alarm condition when the oxygen
concentration is below 82% volume fraction. (5) Malfunction technical alarm condition. (6) The delivery of an
oxygen dose, in normal condition or an indication of abnormal operation.
