Oxygen recycling system
Oxygen recycling system (ORS) is a new technology developed by the Indian Navy in response to the on-going oxygen shortage. It was conceptualised and designed by the Diving School of the Southern Naval Command. This system is capable of increasing the life of the existing medical oxygen cylinders two to four times. It works based on the fact that the lungs absorbs only a miniscule percentage of oxygen and rest are exhaled along with the carbon dioxide.
