  • The device may be used in Homes or Hospital type facilities for patients with chronic obstructive pulmonary diseases (COPD), chronic hypoxemia and pulmonary edema.
  • It may be used as an adjunct treatment for severe sleep apnea (in conjunction with a continuous positive airway pressure unit).
Salient Technical Competing Features: 

Oxygen enrichment unit is a device, which concentrates the Oxygen from the air around us by selectively removing nitrogen to supply an oxygen-enriched air. The concentrated Oxygen is delivered to the patient with breathing-related problems through oxygen mask or nasal cannula to improve Oxygenation in the blood.

It works on the principle of Pressure Swing Adsorption (PSA) and utilizes Zeolite Columns for selective removal nitrogen from air under certain pressure, thereby increasing the Oxygen Concentration.


Low Flow:

  • Flow Rate: 0.5-5 LPM
  • Oxygen purity: 90 - 96%

Medium Flow:

  • Flow Rate: 5-10 LPM
  • Oxygen purity: 70 - 90%

High Flow:

  • Flow Rate: 10-30 LPM
  • Oxygen purity: 30 - 70%

With an optional plug-in module, the same unit can work in high altitudes as well (up to 14000 ft). However, the maximum flow will be reduced to 10 LPM and more than 90% oxygen enrichment will be available until 1.5 LPM.
