2.0 Operational Check and Oxygen Concentration Test
2.1 Description of Operation
Air is drawn into the NewLife Intensity 10 Oxygen Concentrator through an external air intake gross particulate filter. Before this air enters the compressor, it passes through the unit’s suction resonator which, quiets the compressor’s suction sound. Pressurized air then exits the compressor and passes through a heat exchanger. The heat exchanger reduces the temperature of the compressed air. Next, a two-way solenoid feed valve directs the air into one of two sieve beds that contain molecular sieve. The unique property of molecular sieve enables it to physically attract (adsorb) nitrogen when air passes through this material, thus producing high concentrated oxygen.
There are two sieve beds: while one produces high concentration oxygen, the other is purged of the nitrogen it adsorbed (collected) during this pressure swing adsorption (PSA) cycle. Each adsorber produces oxygen and delivers it to the product tank. Oxygen exits the product tank through a pressure regulator, flow control valve, and flowmeter. The NewLife Intensity 10 unit delivers up to 95.5% oxygen at flow rates from 2-10 lpm.
2.2 Operation Check
AirSep tests every NewLife Intensity 10 Oxygen Concentrator thoroughly after manufacture. You must perform the following test to ensure that no damage occurred in shipping or handling.
Do not use extension cords with this unit or connect too many plugs into the same electrical outlet. The use of extension cords could adversely affect the performance of the device. Too many plugs into one outlet can result in an overload to the electrical panel, causing the breaker/fuse to activate or fire if the breaker or fuse fails to operate.
1. Open and inspect all cartons (that contain units) upon delivery. Unpack the unit
and remove it from the carton. Inspect the unit itself for damage. If the exterior of a unit’s carton is damaged, or the unit itself is damaged, note it on the freight bill signed by the driver.
2. Connect unit to power, and set the I/0 power switch to the “I” position. Check to
see that the following occurs:
a. A continuous alarm sounds for approximately five seconds. See the
troubleshooting chart in Section 6.3 of this manual if the unit’s alarm does anything other than sound for five seconds.
b. The compressor runs and flow is indicated in flowmeter. c. OPTIONAL: The Oxygen Monitor’s amber light remains on until
the oxygen concentration reaches 85% ±3% (approximately two minutes). Perform an oxygen concentration test, as described in Section 2.4.
2.3 Alarm System
The NewLife Intensity 10 Oxygen Concentrator is equipped with a battery-powered alarm system, which sounds a continuous and loud alarm when a power failure occurs. It sounds an intermittent alarm if the high or low pressure indicators are activated or if the optional
MN134-1 rev B

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 10 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.
