It is a known fact that at the beginning of the Covid-19 pandemic there were shortages of ventilators. Scientists at CSIR-NAL came forward along with medical professionals from CSIR-IGIB in order to find a solution. They have indigenously designed and developed SwasthVayu– the non-invasive bi-level positive airway pressure ventilator. Along with, treating Covid-19 patients it has additional features to make the country technologically self-reliant. An expert committee evaluated this device and after careful evaluation, it released a statement that Covid-19patients can be aided by SwasthVayu who require oxygen supplementation up to 35%.
SwasthVayu is built using a microcontroller-based closed-loop adaptive control system. It has a built-in 3D printed biocompatible manifold and a couple with Highly EfficientParticulate Air Filter (HEPA filter). These features are effective in curbing the virus spread. It has many unique features like Spontaneousmode, Auto mode, CPAP, Bi-Timed and provision to connect externally to the Enrichmentunit or Oxygen concentrator.
Keeping the critical use of the ventilator, it has gone through stringent tests for bio-compatibility, Electrical Safety, and performance at an accredited agency. Further, the ventilator has conducted successful trials at Mysore Medical College &Research Institute and Command Hospital, Bangalore on 50 Covid-19patients. The clinical trial reports clearly bring out that the performance of “SwasthVayu” ventilator device is satisfactory and effective in improving saturation during use of forCovid-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, CommandHospital, Bangalore and Mysore Medical College & Research Institute, Mysore.
This technology is being commercialized by CSIR-NAL with six private companies. To strengthen the Atnanirbhar movement, one of these 6 companies is in the MSME category. It has set up the production facilities to manufacture 300 units per week. An order for the supply of 1200 SwasthVayu is bagged by CSIR-NAL recently.
