This system focuses on reducing oxygen waste and also reduces the workload on health workers as it does not have to constantly monitor the flow of oxygen.
If normal medical oxygen cylinders are used, the oxygen flow must be regulated manually. The new Oxycare system regulates the oxygen supply by monitoring the patient’s SpO2 level.
The Oxycare System provides supplemental oxygen based on SpO2 levels and prevents the person from falling into a state of hypoxia (low oxygen levels) that can be fatal. This system was developed by Defense Bio-Engineering & Electro Medical Laboratory (DEBEL) in Bengaluru, DRDO, for soldiers stationed at extreme altitudes.
“The system was specially developed for operation under field conditions and is robust. It can be used effectively to treat COVID-19 patients, ”the statement told the media.
Two variants of the Oxycare system
Two variants of the system were configured. The basic version consists of a 10 liter oxygen bottle, a pressure regulator with flow regulator, a humidifier and a nasal cannula. The oxygen flow is controlled manually based on the SpO2 values.
In the second configuration, the oxygen cylinder is equipped with electronic controls that automatically regulate the oxygen flow through a low pressure regulator and an SpO2 probe.
The government is buying 1 lakh manual units and 50,000 automatic oxycare systems along with non-rebreather masks.
The SpO2-based oxygen delivery system optimizes oxygen consumption based on the patient’s SpO2 value and effectively increases the life of portable oxygen cylinders. Health care professionals can adjust the SpO2 threshold to initiate flow out of the system. A display is used to continuously monitor the SpO2 values.
The government claims that the workload and exposure of health care providers will be significantly reduced by eliminating the need for routine measurements and manual adjustments to oxygen flow.
The automated system also provides an appropriate audio alert for various failure scenarios, including low SpO2 levels and probe shutdowns.
“The non-rebreather masks are integrated into the Oxycare systems to use oxygen efficiently. This saves oxygen by 30-40%. The non-rebreather masks must be changed for each patient. These Oxycare systems can be used in homes, quarantine centers, Covid Care centers and hospitals, ”he added.
