Jivan Vayu: IIT Ropar’s power- free CPAP device

Indian Institute of Technology, Ropar has developed a device ‘Jivan Vayu’ as a substitute for CPAP (Continuous positive airway pressure) machine.

About Jivan Vayu

  • This device functions even without electricity.
  • It is adapted to both kinds of oxygen generation units namely, O2 cylinders and oxygen pipelines in hospitals.
  • Apart from fulfilling all medically required parameters, this device is leak-proof and having low-cost.
  • It has been designed for a 22mm CPAP closed-circuit tube.
  • Device can even be customised as per size of the tube.
  • As the device runs during power failures, it can be used to safely transport a patient.
  • It has been manufactured using 3D printing and has been tested mechanically.
  • Device can deliver high flow oxygen (20–60 LPM) and can maintain a continuous positive pressure of up to 20 cm H2O.
  • It has been designed to maintain a FiO2 of above 40 per cent and PEEP (positive end-expiratory pressure) of 5-20 cm H2O.

Viral Filter

Jivan Vayu has an inbuilt viral filter at air entrainment end, with viral efficacy of 99.99 per cent. This filter ensures that air does not bring in any pathogens from environment.

Why it was developed?

This device was need of the hour amid the covid-19 pandemic when power supply is a key concern for saving lives of those who are on medical equipment like ventilators and oxygen concentrators.
