DRDO has an answer for O2 needs DRDO has an answer for O2 needs ByHemanth CSHemanth CS / Updated: Apr 21, 2021, 06:00 IST Gadget used for soldiers posted at high-altitude areas can help moderate covid patients at home An Defence Research and Development Organisation ( DRDO) laboratory for soldiers posted at high-altitude areas could come handy to address the covid-19 situation. Defence Bio-Engineering & Electro Medical Laboratory (DEBEL), whose primary work focuses on development of bio-medical and electro-medical soldier support systems, has developed SpO2 (Blood Oxygen Saturation) supplemental Oxygen Delivery System for soldiers posted at extreme high-altitude areas. The system delivers supplemental oxygen based on the SpO2 levels and prevents the person from sinking into a state of hypoxia, a state in which the amount of oxygen reaching the tissues is inadequate to fulfil the energy requirements of the body.
