Its intended function and use is to provide supplemental oxygen to patients with respiratory disorders, by separating nitrogen from room air, by way of a molecular sieve. It is not intended to sustain or support life. Oxygen is delivered to the user by means of standard oxygen supply tubing and a standard nasal cannula, which are not supplied with the device. A standard humidifier bottle may be used, if desired. The front panel of the device contains the controls and indicators. These include a standard barb fitting for attaching the oxygen tubing, the adjustable flow meter, a power light indicator, an elapsed time meter, and a standard on/off rocker type power switch. # Intended Use of the Device: The LFY-I-5 Oxygen concentrator is a 5-liter per minute oxygen concentrator that is of the pressure swing adsorption (PSA) type. The pneumatic system consists of 5 major components: inlet filtration, air compressor and heat exchanger, synthetic Zeolite molecular sieve beds and {1}------------------------------------------------ Image /page/1/Picture/0 description: The image shows a logo with a circular design featuring horizontal lines and a stylized letter "Z" in the center.
