An indigenous oxygen-dosing device to conserve oxygen using patient monitoring system
The system designed to work with the patient monitoring system. The system obtains respiratory impedance pneumograph using two ECG (electrocardiogram) electrodes placed over the chest, along with SpO2 which is used to measure oxygen saturation in the blood. The impedance pneumography signal is used for identifying the inspiration phase of a patient. The controller circuit identifies the variation in impedance during respiration. Additionally, the oxygen level of the patient is also measured by the SpO2 probe. Normally, oxygen dose is controlled according to the patient’s SpO2 level. This respiratory impedance pneumography circuit checks for the inspiration signal when the SpO2 level goes low. The solenoid valve is opened by comparing the signals obtained from the patient.

The advantage of this oxygen-dosing device is that it has redundancy to avoid false triggering and it can be used across all age groups.
