Context: CSIR - National Aerospace Laboratories (NAL) Bangalore, a constituent lab of CSIR has developed a Non Invasive BiPAP Ventilator - SwasthVayu to treat COVID-19 patients.

BiPAP (also referred to as BPAP) stands for Bilevel Positive Airway Pressure, and is very similar in function and design to a CPAP machine (continuous positive airway pressure). 

  • Similar to a CPAP machine, A BiPAP machine is a non-invasive form of therapy for patients suffering from sleep apnea(temporary cessation of breathing, especially during sleep).
  • The main difference between BiPAP and CPAP machines is that BiPAP machines have two pressure settings: the prescribed pressure for inhalation (ipap), and a lower pressure for exhalation (epap). 
  • The dual settings allow the patient to get more air in and out of their lungs.


About the ventilator:  

  • BiPAP Non-Invasive ventilator comes with a 3D printed manifold & coupler and HEPA filter (Highly Efficient Particulate Air Filter). 
  • These unique features help to alleviate the fear of the virus spread. 
  • It has features like Spontaneous, CPAP, Timed, AUTO BIPAP modes with provision to connect Oxygen concentrator or Enrichment unit externally.  
  • The system has been certified for safety and performance by the National Accreditation Board for Testing and Calibration Laboratories (NABL)(a Constituent Board of Quality Council of India) accredited agencies. 
  • The system has undergone stringent biomedical tests and beta clinical trials at NAL Health Centre.

The major advantage of this machine:

  • It is simple to use without any specialized nursing, cost effective, compact and configured with a majority of indigenous components. 
  • This is ideal for treating COVID -19 patients in Wards, Makeshift Hospitals, dispensaries and homes in the current Indian COVID 19 scenario.

CSIR-NAL is in process of taking it forward with the regulatory authorities for approval and expected to get it shortly. CSIR-NAL has already initiated dialogue with major public/private industries as a partner for mass production.
