A Survey of Photoplethysmography and Imaging Photoplethysmography Quality Assessment Methods

open access: yesApplied Sciences, 2022
Photoplethysmography is a method to visualize the variation in blood volume within tissues with light. The signal obtained has been used for the monitoring of patients, interpretation for diagnosis or for extracting other physiological variables (e.g ...

Modified Allen Test Assessment via Imaging Photoplethysmography

open access: yesCurrent Directions in Biomedical Engineering, 2023
The modified Allen test (MAT) is a widely used tool to examine the perfusion capacities of the arteries (ulnar or radial) of the hand. In clinical practice, MAT is utilized to ensure that in the event of occlusion, remaining vessels guarantee sufficient ...

USING PHOTOPLETHYSMOGRAPHY IMAGING FOR OBJECTIVE CONTACTLESS PAIN ASSESSMENT

open access: yesActa Polytechnica, 2014
This work presents an extension to the known Analgesia Nociception Index (ANI), which provides an objective estimation of the current depth of analgesia. An adequate “measure” would facilitate so-called balanced anesthesia.

Photoplethysmography Revisited: From Contact to Noncontact, From Point to Imaging [PDF]

open access: yesIEEE Transactions on Biomedical Engineering, 2016
Photoplethysmography (PPG) is a noninvasive optical technique for detecting microvascular blood volume changes in tissues. Its ease of use, low cost and convenience make it an attractive area of research in the biomedical and clinical communities. Nevertheless, its single spot monitoring and the need to apply a PPG sensor directly to the skin limit its
