COVID-19: ISRO Develops 3 Types Of Ventilators, To Transfer Technology

The ventilator can deliver the required flow of oxygen-air mixture to the patient's lung at a desired rate set by the clinicians.

The Indian Space Research Organisation has developed three types of ventilators, and has come forward to transfer the technology to industry for clinical usage as the country battles the second wave of COVID-19 pandemic. A low-cost and portable critical care ventilator, ''PRANA'' ("Programmable Respiratory Assistance for the Needy Aid'') is based on the automated compression of an AMBU (Artificial Manual Breathing unit) bag. The system has a sophisticated control system that includes airway pressure sensor, flow sensor, oxygen sensor, servo actuator as well as expiration and PEEP (Positive End Expiratory Pressure) control valves, according to an interest exploration note posted on the website of Bengaluru-headquartered space agency. The clinicians can select the ventilation mode and set the required parameters through a touch screen panel and monitor various parameters like pressure, flow, tidal volume and oxygen concentration on the same screen.
