Published on April 20, 2021
Current Context: The Supplemental Oxygen Delivery System is developed by Defence Research Development Organisation (DRDO).
Supplemental Oxygen Delivery System--DRDO
  • The system will be used by soldiers who are posted at extreme high-altitude areas and by COVID-19 patients.
  • It is an automatic system that delivers supplemental oxygen based on the SpO2 (blood oxygen saturation) levels and prevents the person from sinking to a state of hypoxia, which is fatal in most cases if it sets in.
  • The system is developed by DRDO’s lab which is named Defence Bio-Engineering & Electro Medical Laboratory (DEBEL) in Bengaluru.
  • The electronic hardware of the system is designed in such a way that it operates at extremely low temperature, low humidity and low barometric pressures.
  • The system reads the SpO2 levels of the person through a wrist-worn pulse oximeter. Based on the SpO2 levels, the solenoid valve is adjusted to supply oxygen to the person and thus the system delivers oxygen through nasal nares.
  • It supplies oxygen for 750 minutes at a flow rate of two litres per minute and is low in weight.
