NAL develops Ventilator 'SwasthVayu' for COVID-19 patients

National Aerospace Laboratories (NAL), Bangalore has developed BiPAP ventilator named SwasthVayu, a non-invasive (involves use of masks or similar device) breathing support device, for the use of non-critical non-ICU cases of Covid-19.
BiPAP stands for Bilevel Positive Airway Pressure. It is a type of positive pressure ventilator.
While using BiPAP, positive air pressure is received during breathing in and breathing out. But higher air pressure is received during breathing in.
SwasthVayu is connected with an oxygen concentrator, and will be ideal to treat moderate or mid-stage severe Covid-19 patients who do not require intubation and invasive ventilation.
The system has been certified for safety and performance by the National Accreditation Board for Testing and Calibration Laboratories (NABL).
