                     3 Types of 
Ventilators 
developed by 
ISRO
Introduction
The Indian Space Research 
Organisation (ISRO) 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.

Programmable 
Respiratory 
Assistance for 
the Needy Aid
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.

Control System
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.

Parameters
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.

Provision to 
attach external 
battery
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.

Invasive and 
non-invasive 
ventilation 
modes
ISRO said 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).

Robust 
algorithm
A robust algorithm for controlled 
and safe ventilation of the patient 
is implemented which raises alarm 
and opens safety valves to prevent 
barotrauma, asphyxia during the 
ventilation.

Provisions to 
attach bacterial 
viral filters
There are provisions to attach 
bacterial viral filters at each 
interface to prevent cross-infection 
and the contamination of air.

Positive 
pressure 
mechanical 
ventilator
The ICU grade positive pressure 
mechanical ventilator titled ‘VaU’ 
(Ventilation assist Unit) can assist 
or replace the spontaneous 
breathing in patients under 
respiratory distress, ISRO said.

Space Ventilator 
Aided System 
for Trauma 
Assistance
Gas-powered ventilator ‘Space 
Ventilator Aided System for Trauma 
Assistance (SVASTA)’, a basic mode 
for non-invasive ventilation, is well-
suited for emergency use for first 
line treatment and as transit 
ventilators inside vehicles, 
according to ISRO.
