Photoplethysmography for the Assessment of Haemorheology [PDF]
Scientific Reports, 2017 AbstractHaemorheology has been long identified as an early biomarker of a wide range of diseases, especially cardiovascular diseases. This study investigates for the first time the suitability of Photoplethysmography (PPG) as a non-invasive diagnostic method for haemorheological changes.

Feasibility of Imaging Photoplethysmography [PDF]
2008 International Conference on BioMedical Engineering and Informatics, 2008 Contact and spot measurement have limited the application of photoplethysmography (PPG), thus an imaging PPG system comprising a digital CMOS camera and three wavelength light-emitting diodes (LEDs) is developed to detect the blood perfusion in tissue.

Photoplethysmography in Normal and Pathological Sleep [PDF]
Sensors, 2021 This article presents an overview of the advancements that have been made in the use of photoplethysmography (PPG) for unobtrusive sleep studies. PPG is included in the quickly evolving and very popular landscape of wearables but has specific interesting properties, particularly the ability to capture the modulation of the autonomic nervous system ...

Central Sleep Apnea Detection by Means of Finger Photoplethysmography
IEEE Journal of Translational Engineering in Health and Medicine, 2023 Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA) are two types of Sleep Apnea (SA) with different etiologies and treatment options. Home sleep apnea testing based on photoplethysmography-derived peripheral arterial tonometry (PAT HSAT) has ...
