Journal ArticleDOI
A review of machine learning techniques in photoplethysmography for the non-invasive cuff-less measurement of blood pressure
C El-Hajj,Panayiotis A. Kyriacou +1 more
TL;DR: A comprehensive review for non-invasive cuff-less blood pressure estimation using the PPG approach along with their challenges and limitations is provided.
Journal ArticleDOI
Experimental and numerical investigations of the optical and thermal aspects of a PCM-glazed unit
TL;DR: In this paper, thermal and optical characterisation of PCM (phase change material) RT27 using the T-history method and spectrophotometry principles, respectively, and the experimental and numerical performance evaluation of a PCM-glazed unit were developed, and validated in a numerical CFD model.
Journal ArticleDOI
Pulse oximetry in the oesophagus
TL;DR: The report will be focused on the description of a new oesophageal photoplethysmographic/SpO(2) probe, which was developed to investigate the suitability of the Oesophagus as an alternative monitoring site for the continuous measurement of SpO( 2) in cases of poor peripheral circulation.
Journal ArticleDOI
Investigation of oesophageal photoplethysmographic signals and blood oxygen saturation measurements in cardiothoracic surgery patients
TL;DR: The results suggest that the arterial blood circulation to the oesophagus is less subject to vasoconstriction and decreased PPG amplitudes than are the peripheral sites used for pulse oximetry such as the finger.
Journal ArticleDOI
Esophageal pulse oximetry utilizing reflectance photoplethysmography
TL;DR: The results confirm that the esophagus may be used as an alternative monitoring site for pulse oximetry even in patients with compromised peripheral perfusion.
