Determination of tissue oxygen saturation by diffuse reflectance spectroscopy. [PDF]

J Biomed Opt, 2023
Tissue oxygenation is a parameter that allows for determining the health status of human beings. In diabetic patients, it is particularly important to evaluate this parameter as an indicator of microcirculatory problems in the extremities.We aim to obtain tissue oxygen saturation from diffuse reflectance measurements.A computational algorithm to ...

Correlation between regional tissue perfusion saturation and lactate level during cardiopulmonary bypass [PDF]

Korean Journal of Anesthesiology, 2018
Background Cardiopulmonary bypass (CPB) can cause systemic hypoperfusion, which remains undetected by routine monitoring of physiological parameters. Noninvasive tissue perfusion monitoring offers a clinical benefit by detecting low systemic perfusion ...

Oxygen Saturation Imaging Using LED-Based Photoacoustic System

Sensors, 2021
Oxygen saturation imaging has potential in several preclinical and clinical applications. Dual-wavelength LED array-based photoacoustic oxygen saturation imaging can be an affordable solution in this case. For the translation of this technology, there is

pFOE or pFTOE as an Early Marker for Impaired Peripheral Microcirculation in Neonates

Children, 2022
Background: Peripheral-muscle-fractional-oxygen-extraction (pFOE) and peripheral-muscle-fractional-tissue-oxygen-extraction (pFTOE) are often equated, since both parameters are measured with near-infrared-spectroscopy (NIRS) and estimate oxygen ...

Arterial and Venous Pressure Monitoring during Cardiopulmonary Resuscitation for Out-of-Hospital Arrests: Four Case Reports

Journal of Vascular Diseases, 2023
Background: A new physiological monitoring system that simultaneously measures femoral arterial pressure, femoral venous pressure, and cerebral tissue oxygen saturation during CPR was used to evaluate the quality of cardiopulmonary resuscitation. In this
