An oxygen enrichment unit (OEU) developed indigenously by the Council for Scientific and Industrial Research (CSIR) to treat Covid patients has a spin-off for the defence forces in high-altitude areas as it may be used at heights the place such gear usually doesn’t operate.

Commercially obtainable OEUs typically work until an altitude of 8,000 toes above sea degree. With an elective plug-in module, CSIR’s unit can work up to an altitude of 14,000 toes, thereby making it useful for use throughout contingencies in high-altitude battlefield areas the place rarefied air and excessive local weather could cause medical emergencies.

OEU is a tool which concentrates oxygen from the encircling air by selectively eradicating nitrogen to provide oxygen-enriched air. The concentrated oxygen is delivered to patients with respiratory issues by means of a masks or a nasal cannula.

Designed by CSIR’s Central Mechanical Engineering Research Institute (CMERI), the gadget could also be used in distant locations, properties or hospitals for patients with power obstructive pulmonary ailments (COPD), power hypoxemia and pulmonary edema. It will also be used as an adjunct therapy for extreme sleep apnoea in conjunction with a steady constructive airway stress unit.

According to Prof Harish Hirani, director, CMERI, the unit could also be very helpful for properties and hospitals in addition to defence forces, notably in high-altitude terrain and distant localities, moreover being more practical and essential for treating Covid patients. He mentioned this unit may cut back the demand for oxygen cylinders and ventilators and due to the rise in air air pollution its demand is predicted to develop quickly as it’s helpful in sustaining correct oxygen ranges for an optimum wholesome atmosphere.

The unit works on the precept of “pressure swing adsorption” to take away nitrogen from the air below sure stress utilizing a compressor and valves, thereby rising the oxygen focus.

CSIR’s unit is able to delivering up to 30 litre per minute (LPM) of oxygen-enriched air, which is absent in the opposite commercially obtainable models. It is claimed to give an outflow of 93 per cent oxygen focus degree as in contrast to 27-35 per cent by different models. The machine can even regulate air movement with accuracy 0.5 LPM, which can assist in high-flow oxygen remedy, a greater methodology in therapy and administration of Covid patients.

After testing, validation and benchmarking, the expertise for manufacturing the OEU has been transferred by CMERI to a non-public agency for industrial manufacturing and a unit prices about Rs 35,000.
