“…Clarke et al managed to record clean PPG signals. After that, they contaminated the PPG signal by adding identical noise additive white Gaussian noise (AWGN) to both the red and infrared PPG signals [22]. The aim of Joseph et al is to determine the different parameters of PPG signal [23].…”

“…They used the wavelet de-noising approach to remove AWGN from the synthetic PPG signal. In [10] and [22], the simulation was performed on the synthesized motion corrupted PPG signal, while we consider the practical motion corrupted PPG signal to develop our PO system. Ram et al proposed an adaptive step-size least mean squares adaptive filter to reduce the motion artifact corrupted PPG signal [24].…”

Clinical devices play a vital role in diagnosing and monitoring people’s health. A pulse oximeter (PO) is one of the most common clinical devices for critical medical care. In this paper, we explain how we developed a wearable PO. We propose a new electronic circuit based on an analog filter that can separate red and green photoplethysmography (PPG) signals, acquire clean PPG signals, and estimate the pulse rate (PR) and peripheral capillary oxygen saturation (SpO2). We propose a PR and SpO2 measurement algorithm with and without the motion artifact. We consider three types of motion artifacts with our acquired clean PPG signal from our proposed electronic circuit. To evaluate our proposed algorithm, we measured the accuracy of our estimated SpO2 and PR. To evaluate the quality of our estimated PR (bpm) and SpO2 (%) with and without the finger motion artifact, we used the quality evaluation metrics: mean absolute percentage error (MAPE), mean absolute error (MAE), and reference closeness factor (RCF). Without the finger motion condition, we found that our proposed wearable PO device achieved an average 2.81% MAPE, 2.08 bpm MAE, 0.97 RCF, and 98.96% SpO2 accuracy. With a finger motion, the proposed wearable PO device achieved an average 4.5% MAPE, 3.66 bpm MAE, 0.96 RCF, and 96.88% SpO2 accuracy. We also show a comparison of our proposed PO device with a commercial Fingertip PO (FPO) device. We have found that our proposed PO device performs better than the commercial FPO device under finger motion conditions. To demonstrate the implementation of our wearable PO, we developed a smartphone app to allow the PO device to share PPG signals, PR, and SpO2 through Bluetooth communication. We also show the possible applications of our proposed PO as a wearable, hand-held PO device, and a PPG signal acquisition system.

“…In sports that have a slow onset or a longer intensity as seen in our golf research, hypoxemia is less common. Therefore, we did not take measurements during the sport performance [12], but after 15 minutes, as it has been shown [21] that hypoxemia occurs during and after the immediate cessation of the sport performance [4].…”

The health effects of playing golf on the athlete's body is an interesting topic. The effect of golf on increasing blood saturation has low presence in the literature. This paper demonstrates the correlation of playing golf on improving health status after COVID-19 while this positive information has a potential to be used by the marketing management of various organisations to improve economics of golf activities. We analyse the change in saturation and heart rate after playing an 18-hole course, measured by pulse oximetry (% SpO2). Then we investigate the different aspects that have the greatest health benefit in golf. By following the effect of playing golf on blood oxygen saturation and heart rate in athletes we build a linear regression model explaining the impact 14 factors have on blood oxygen saturation. An 18-hole golf course caused a 1 ± 1.49% (p < 0.001) increase in venous blood O2 concentration and a 6 ± 8.09% (р < 0.001) increase in resting heart rate. Golf has the positive effect on the health status of athletes after recovery or vaccination for COVID-19 disease.

Signal Quality Analysis in Pulse Oximetry: Modelling and Detection of Motion Artifact

View full text Add to dashboard Cite

Pulse oximetry is a non-invasive technique for measuring the amount of oxygen in a patient's arterial blood, as a percentage of the blood's oxygen carrying capacity (SpO 2 ). This measurement is considered standard of care in the hospital for monitoring the cardio-respiratory function of a patient. While it has potential uses in ambulatory or wearable monitoring applications, pulse oximetry is particularly susceptible to motion artifact contamination. This thesis presents efforts to quantify and model the effects of motion artifact, and automatically detect periods of poor signal quality.First, the effects of motion artifact on SpO 2 are analyzed using motion contaminated data. Second, two models are identified from previous literature that may explain the effects of motion artifact on pulse oximetry. These models are developed analytically and evaluated using isolated motion artifact signals. Finally, three automatic signal quality assessment algorithms are proposed. These algorithms are shown to discriminate between clean and motion contaminated signals.Overall, this thesis attempts to inform the development of software and hardware based techniques to mitigate the effects of poor signal quality on pulse oximetry.iii
