CSIR scientists develop non-invasive ventilator

In an effort to address the shortage of ventilators when COVID-19 hit the country, CSIR-NAL scientists along with medical professionals from CSIR-IGIB developed the non-invasive bi-level positive airway pressure ventilator –SwasthVayu.

The performance of the device has been evaluated by the expert committee constituted by Director General of Health Services, Ministry of Health & Family Welfare, the Government of India.  The panel has concluded that SwasthVayu may be used on COVID-19 patients who require oxygen supplementation up to 35 per cent.

SwasthVayu is a microcontroller based precise closed-loop adaptive control system with a built-in biocompatible “3D printed manifold and coupler” with HEPA filter (Highly Efficient Particulate Air Filter).  These unique features help to alleviate the fear of the virus spread.  It has features like CPAP, Bi-Timed, Spontaneous / AUTO modes with provision to connect Oxygen concentrator or Enrichment unit externally.

The ventilator has gone through stringent tests for Electrical safety, performance and bio-compatibility at NABL accredited agency. The SwasthVayu has successfully conducted clinical trials at Command Hospital, Bengaluru and Mysore Medical College & Research Institute, Mysuru on 50 COVID-19 patients.

The clinical trial reports established that the performance of “SwasthVayu” ventilator device is satisfactory and effective in improving saturation during use for COVID-19 patients. It is the culmination of dedicated efforts of medical professionals at CSIR-IGIB and aerospace scientists at CSIR-NAL including support from CSIR-NAL Health Center, Command Hospital, Bengaluru and Mysore Medical College & Research Institute, Mysuru.

CSIR-NAL has commercialised this technology with six private companies and one of these companies (which is in the MSME category) has set up the production facilities for almost 300 units a week. CSIR-NAL recently bagged an order for supply of 1,200 SwasthVayu machines to Delhi Government, and the execution and installation at various hospitals in Delhi is under way.  With this, the country is now self-reliant in this technology, which is a major achievement under the Atmanirbhar vision of the Government of India.
