Comparison of pulse pressure and stroke volume variations measured by three monitors in high-risk surgical patients

Heliyon
Introduction: Dynamic indices of fluid responsiveness (FR) such as pulse pressure variation (PPV) and stroke volume variation (SVV) differ among hemodynamic monitors, which use proprietary algorithms, and vary even over a short period of time.

An experimental investigation on pulse transit time and pulse arrival time using ecg, pressure and ppg sensors

Medicine in Novel Technology and Devices, 2023
Pulse transit time (PTT) and pulse arrival time (PAT) are explored using multiple sensors connected to the human body. Pulse wave velocity (PWV) is indirectly computed using PTT. We conducted a study using ECG, Pressure, and PPG sensor to capture the PAT

Echocardiographic measure of dynamic arterial elastance predict pressure response during norepinephrine weaning: an observational study

Scientific Reports, 2021
The purpose of this study was to determine whether dynamic elastance EAdyn derived from echocardiographic measurements of stroke volume variations can predict the success of a one-step decrease of norepinephrine dose.

Evaluation of least significant changes of pulse contour analysis-derived parameters

Annals of Intensive Care, 2019
Background Many maneuvers assessing fluid responsiveness (minifluid challenge, lung recruitment maneuver, end-expiratory occlusion test, passive leg raising) are considered as positive when small variations in cardiac index, stroke volume index, stroke ...
