An Indigenous Oxygen Dosing Device To Conserve Oxygen Using Patient Monitoring System
Project Description :

Abstract oxygen dosing devices are designed to deliver oxygen only during inspiration phase of respiration cycle. in previous works they used pressure sensors to identify inspiration phase. in my work the oxygen dosing devices are designed to work along with the patient monitoring system. the system obtains respiratory impedance pneumography signal using two ecg electrodes placed over chest region along with spo2 which is used to measure oxygen saturation in blood. the impedance pneumography signal is used for identifying inspiration phase of a patient. the controller circuit identifies the variation in impedance during respiration. additionally oxygen level of the patient is also measured by spo2 probe. normally oxygen dose is controlled according to the patients spo2 level. my respiratory impedance pneumography circuit checks for the inspiration signal when spo2 level goes low. the solenoid valve is opened by comparing the signals obtained from the patient. the solenoid valve is controlled with the help of labview daq. this setup can also be used for monitoring apnea. a visual indication alarms if inspiration is not sensed for ten seconds. the advantage of this oxygen dosing device is it has redundancy to avoid falls triggering and it can be used for all age groups of patients. keywords: inspiration phase, respiration cycle, pressure sensor, patient monitoring system, respiratory impedance pneumography, spo2, solenoid valve, apnea monitoring.
