Defence Research and Development Organisation has developed a SpO2-based supplemental oxygen delivery system for soldiers serving in extremely high altitude areas & COVID-19 patients. This automatic system delivers supplemental oxygen based on the SpO2 (blood oxygen saturation) levels & prevents the person from sinking into a state of hypoxia, which is fatal in most cases.

Hypoxia is a condition in which the amount of oxygen reaching the tissues is inadequate to fulfil all the energy requirements of the body. This is exactly the situation that gets replicated in a COVID-19 patient due to the virus infection and has been leading to the current crisis, If a COVID-19 patient’s SpO2 level goes below 94 per cent, he or she is generally advised to contact the doctor immediately as hospitalisation may be necessary.
