Technology Transfer of AMBU Bag based Critical Care Ventilator- ‘PRANA’

Interest Exploration Note

VSSC/ISRO has developed a low-cost and portable critical care ventilator named ‘PRANA’ (प्राण)- “Programmable Respiratory Assistance for the Needy Aid”. The ventilator is based on the automated compression of an AMBU 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 control valves.

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, oxygen concentration, etc. on the same screen. The ventilator can deliver the required flow of oxygen-air mixture to the patient’s lung at a desired rate set by the clinicians. It has a provision to attach external battery for backup during power failure.

PRANA supports both invasive and non-invasive ventilation modes and is capable of giving mandatory breaths (controlled by ventilator) as well as spontaneous breaths (controlled by the patient). A robust algorithm for controlled and safe ventilation of the patient is implemented which raises alarm and opens safety valves to prevent barotrauma, asphyxia and apnea during the ventilation. Alarm is also raised in case of wrong or improper connection of the ventilation circuit or inadvertent disconnection of the hose or sensors. There are also provisions to attach bacterial viral filters at each interface to prevent cross- infection and the contamination of air(वायु).
