The Mark 5 Nuvo Lite Family begins their operation with air being pulled into the external air intake filter. This filtered air enters the compressor via a suction resonator and fine filter. Pressurized air then exits the compressor and passes through a heat exchange, which reduces the temperature of the compressed air. Next, an electronic valve system directs the air into one of two tubes that contain molecular sieve ( sieve beds ). The molecular sieve adsorbs ( physically attracts ) the nitrogen from the air as it is pushed through the sieve beds. This alows the oxygen enriched product gas to pass through before being delivered to the pressure regulator. As one tube is generating the product gas, the other is being purged of the adsored nitrogen, this process is called pressure swing adsorption ( PSA ). After passing through the regulator, the rate of product gas being delivered to the patient is set by the flow meter adjusting valve. Finally, it passes through a fine praticle filter and then over a sensor that detects the oxygen concentrator of the product gas before it exits the device through a fire resistant outlet. The product gas is delivered to the patient and absorbed by tissues within the nose, lungs and the pathway between the two.
