IIT Ropar develops the nation's first power-free CPAP device 'Jivan Vayu'

Indian Institute of Technology, Ropar has developed a device ‘Jivan Vayu’ which can be used as a substitute of a CPAP machine.
What is Continuous Positive Airway Pressure (CPAP)?

CPAP is a treatment method for patients having breathing problems during sleep called sleep apnea.
The machine uses mild air pressure to keep the airways open for easy breathing.
It is also used to treat infants whose lungs have not fully developed.
The machine blows air into the baby's nose to help inflate his or her lungs. The treatment is all the more necessary during early stages of the Covid-19 infection.
It reduces lung damage and allow patients to recover from the inflammatory effects.

However, this is Nation’s first such device which functions even without electricity and is adapted to both kinds of oxygen generation units like O2 cylinders and oxygen pipelines in hospitals.
These provisions are not available in otherwise existing CPAP machines.
Fulfilling all the medically required parameters, this leak-proof, low-cost CPAP delivery system, “Jivan Vayu’ is designed for a 22mm CPAP closed circuit tube. It can even be customized as per the size of the tube. Since it can run during power failures, this can be used to safely transport a patient.
It has an inbuilt viral filter at the air entrainment end which has a viral efficacy of 99.99%. The viral filter ensures that the air does not bring in any pathogens from the environment.
The device has been manufactured using 3D printing and has also been tested mechanically.
‘Jivan Vayu’ can deliver high flow oxygen (20–60 LPM) while maintaining a continuous positive pressure of up to 20 cm H2O. The device is designed to maintain an FiO2 of above 40% with a PEEP (positive end-expiratory pressure) of 5-20 cm H2O.
