obtaining an exact measurement of oxygen saturation (SpO2) using a finger-probe based
pulse oximeter is dependent on both artifact-free infrared (IR) and red (R) …

Photoplethysmography (PPG) signals are used in pulse oximetry to calculate peripheral
capillary oxygen saturation (SpO_2) levels. It is well known that the accuracy of the …

Periodic motion artifacts affect photoplethysmography (PPG) signals in activities of daily
living (ADL), cardiopulmonary exercise testing (CPX), and cardiopulmonary resuscitation …

The performance of portable and wearable biosensors is highly influenced by motion
artifact. In this paper, a novel real-time adaptive algorithm is proposed for accurate motion …

Nowadays, technological evolution has allowed advances in several areas, especially in
healthcare. Digital transformation in health has brought benefits to both professionals and …

We introduce a new method to reconstruct motion and noise artifact (MNA) contaminated
photoplethysmogram (PPG) data. A method to detect MNA corrupted data is provided in a …

Objective: Pulse oximetry, a widely accepted method for non-invasive estimation of arterial
oxygen saturation (SpO 2) and pulse rate (PR), is increasingly being adapted for mobile …

Motion artefact is a common occurrence that contaminates photoplethysmographic (PPG)
measurements. To extract timing information from signals during artefact is challenging. PPG …

Corruption of photopleythysmograms (PPGs) by motion artifacts has been a serious obstacle
to the reliable use of pulse oximeters for real-time, continuous state-of-health monitoring. In …

Modern pulse oximeters are employed in critical care units to measure the vital medical
parameters like heart rate and blood oxygen saturation levels. These devices work by …
