DRDO Supplemental Oxygen Delivery System.
                     DRDO SUPPLEMENTAL OXYGEN 
DELIVERY SYSTEM
INTRODUCTION
DRDO's Defense Bio-Engineering 
Electro Medical Laboratory (DEBEL), 
Bengaluru has developed a SpO2 
(Blood Oxygen Saturation) 
supplemental Oxygen Delivery 
System for moderate COVID-19 
patients and soldiers posted at 
extreme high-altitude areas.

DEBEL
The system developed by DEBEL will 
help in delivering supplemental 
oxygen based on the SpO2 levels, 
preventing the person from sinking 
into a state of Hypoxia (fatal in most 
cases, if sets in).

HYPOXIA
It is a state where the amount of 
oxygen reaching the tissues is not 
adequate to meet all the energy 
requirements of the body.

ELECTRONIC 
HARDWARE
As per the press release by the 
Ministry of Defence, the electronic 
hardware of the system is designed to 
function at extreme altitudes with 
low barometric pressures, low 
temperatures and humidity.

SOFTWARE 
SAFETY
The software safety checks which are 
incorporated in the system plays a 
crucial role in ensuring the functional 
reliability of the system in field 
conditions.

HOW DOES THE 
SYSTEM WORK?
The automated system developed by 
DRDO reads the SpO2 levels of an 
individual with the help of a wrist-
worn pulse oximeter module through 
a wireless interface and controls a 
proportional solenoid valve to 
regulate the oxygen supply to the 
patient.

BOON TO THE ONGOING 
COVID-19 PANDEMIC
The system is a boon to the ongoing 
crisis arising due to the COVID-19 
pandemic. 
It can be used in the houses for 
moderate COVID-19 infected patients 
for Oxygen flow therapy with flow 
controlled at 2/5/7/10 lpm flow.
