Instantaneous venous oxygenation estimation using Photoplethysmograph (PPG) waveform
In this study oesophageal photoplethysmograph data from eight patients under positive pressure ventilation was analysed to test the hypothesis that the modulations created by the ventilation in the AC PPG single could be used to estimate the venous saturation. In order to estimate the instantaneous arterial and venous saturation Smoothed-pseudo WignerVille Distribution (SPWVD) was utilised. The...
متن کاملDIFFUSE REFLECTANCE MEASUREMENTS FROM DIFFERENT SURFACES
Relative diffuse reflection measurements from the original and ground surfaces using a He-Ne laser are reported. The intensity measurements for the metallic, transparent dielectric, matte plastic surfaces and colored papers are presented. Our results indicate that among metallic surfaces tested, aluminum has the highest diffuse reflectance; while the original stainless steel surface shows the l...
متن کاملRespiratory Quality Index Design and Validation for ECG and PPG Derived Respiratory Data
Patient vital signs have been widely recognized as an early indicator of catastrophic patient decline in the hospital. This has led to the widespread implementation of Rapid Response Teams (RRTs) and Early Warning Score (EWS) systems within hospitals. However, in order to both RRTs and EWS systems to be most effective, it is critical that patient vital signs are recorded accurately and often. H...
متن کاملHeart rate variability before and after cycle exercise in relation to different body positions.
The purpose of this study was to assess the effect of three different body positions on HRV measures following short-term submaximal exercise. Thirty young healthy males performed submaximal cycling for five minutes on three different occasions. Measures of HRV were obtained from 5-min R to R wave intervals before the exercise (baseline) and during the last five minutes of a 15 min recovery (po...
