Supplemental Oxygen Delivery System--DRDO

Current Context: The Supplemental Oxygen Delivery System is developed by Defence Research Development Organisation (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.
