Objectives: To develop a non-invasive measurement of continuous monitoring of hemoglobin using IoT-enabled pulse oximetry. Currently in India, most women, senior citizens, and rural area people are suffering from anemia. In many cases, people unable to visit hospitals and laboratories for hemoglobin testing. To help the above people our proposed system will measure hemoglobin concentration without visiting the hospital at an affordable price. Methods: We developed real-time continuous monitoring of Hb concentration and oxygen saturation (SpO 2) using pulse oximetry. In this study, 47 healthy volunteers were participated and measure the above-mentioned parameters under resting conditions. Findings: The obtained results were in unison with laboratory measurements with the variation of 0.12g/dL to 1.0g/dL. Novelty/Applications: Experimental results showed the approach of continuous monitoring of hemoglobin and SpO 2 using an IoT-enabled noninvasive method can be useful in healthcare management.
The aim of this study is to quantize mental stress by integrating different physiological markers like reaction time, photoplethysmograph (PPG), heart rate variability (HRV) and subjective markers like questionnaire. The study included 10 subjects of age between 22 and 26 years. Study materials include the results of PSS questionnaire, simple reaction time, PPG data, HRV data during a stress inducing stroop test. The study suggests that mental stress can be quantized when stress is induced acquisitively and more accurate quantification of stress can be achieved by integrating many physiological parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
