“…PPG detection using an image is similar to a reflective pulse oximeter and has the advantage of noncontact measurement of bio-signals such as heart rate, heart rate variability, oxygen saturation, and blood pressure [8,9]. As a representative method for measuring oxygen saturation using a camera, a method for tracking changes in oxygen saturation using blue and red wavelengths with two camera channels or polarization properties has been proposed [10][11][12]. However, this method uses wavelengths in the visible light region that limit the penetration depth or affect the measurement of oxygen saturation by melanin concentration in the skin [13].…”

Here we report the fabrication of a noncontact pulse oximeter system based on a dual-wavelength imaging system and its oxygen saturation monitoring performance during wound healing. The dual-wavelength imaging system consists of 660 nm and 940 nm light-emitting diodes and a multi-spectral camera that simultaneously accepts visible and near-infrared images. Using the proposed system, images were acquired at 30 fps at both wavelengths, and photoplethysmography signals were extracted by specifying a specific region in the images. We removed the signals caused by small movements and smoothed them using the discrete wavelet transform and moving average filter. To confirm the feasibility of the proposed noncontact oxygen saturation system, a wound model was created using a hairless mouse and oxygen saturation was measured during wound healing. The measured values were compared and analyzed using a reflective animal pulse oximeter. Through a comparative analysis of these two devices, the error of the proposed system was evaluated and the possibility of its clinical application and wound healing monitoring through oxygen saturation measurement confirmed.

“…The MAX30100 has integrated Infrared (IR) and Red LED sensors at a low price. While many researchers have developed non-invasive blood oxygen saturation and pulse rate measurement devices [8,9,10,11,12,13,14], we developed a MAX30100-based portable system at the lowest possible cost and analyzed the performance on twelve subjects. A number of sensor-based monitoring systems have already been developed for affordable applications [15,16,17,18], but keeping in mind the issues of sustainability and quality [19,20], we have conducted a performance analysis after the implementation.…”

Covid has killed millions, and millions more are being infected every day. Severe infection causes Pneumonia associated with high pulse and breathing rates, and low blood oxygen. Pulse rate and blood oxygen are two parameters that doctors use to diagnose and measure Pneumonia and Bronchitis. Sensors for their measurement are widely available in developed countries, but their costs are prohibitively high for wide penetration in developing countries. Hardware prototypes incorporated with embedded software and IoT have been developed previously, but their costs have not been brought down sufficiently for wide penetration. We developed and tested the performance of an Atmel ATmega 328P MCU and MAX30100 sensor kit-based pulse rate and blood oxygen monitor. We applied the device on 12 subjects and compared the data with a commercially available, Rossmax SB150 pulse oximeter. A minimal deviation of 0.8175% for pulse rate and 0.425% for blood oxygen was obtained that endorses the accuracy of our algorithm and implementation. Cost analysis shows that implementation can be done at a cheap rate of about US$ 12 only.
