Influence of breathing on variation in cardiac stroke volume at the onset of cycling

Autor: Casper Sejersen, Niels H. Secher, Johannes J. van Lieshout, Marcos P. Rocha

Publikováno v: European journal of applied physiology, 121(11), 3061-3067. Springer Verlag

Purpose: During cycling, the variation in cardiac stroke volume (SVV) is similar to that at rest. However, SVV may be influenced by ventilation at the start of cycling, e.g., by a Valsalva-like maneuver used to stabilize the body. This study evaluate

Hypoxic acclimation negatively impacts the contractility of steelhead trout (Oncorhynchus mykiss) spongy myocardium

Autor: Douglas A. Syme, Jordan C. Roberts, Christian Carnevale, A. K. Gamperl

Publikováno v: American Journal of Physiology-Regulatory, Integrative and Comparative Physiology. 318:R214-R226

Cardiac stroke volume (SV) is compromised in Atlantic cod and rainbow trout following acclimation to hypoxia (i.e., 40% air saturation; ~8 kPa O2) at 10–12°C, and this is not due to changes in heart morphometrics or maximum achievable in vitro end

Noninvasive measurement of stroke volume changes in critically ill patients by means of electrical impedance tomography

Autor: Fabian Braun, Inéz Frerichs, Martin Proença, Josep Solà, Anna Wendler, Norbert Weiler, Mathieu Lemay, Tobias Becher, Jean-Phillipe Thiran

Publikováno v: Journal of Clinical Monitoring and Computing. 34:903-911

Previous animal experiments have suggested that electrical impedance tomography (EIT) has the ability to noninvasively track changes in cardiac stroke volume (SV). The present study intended to reproduce these findings in patients during a fluid chal

Cardiac SERCA activity in sockeye salmon populations: an adaptive response to migration conditions

Autor: Katja Anttila, Erika J. Eliason, Anthony P. Farrell, Scott G. Hinch, David A. Patterson

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 76:1-5

We show that cardiac sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) activity differs considerably among sockeye salmon (Oncorhynchus nerka) populations. Variability in SERCA activity was significantly correlated with elevation gain and temperature

Basics of Electrical Impedance Tomography and Its Application

Autor: Christian Putensen, Thomas Muders, Benjamin Hentze

Publikováno v: Cardiopulmonary Monitoring ISBN: 9783030733865

Electrical impedance tomography (EIT) noninvasively creates images of the local ventilation and arguably lung perfusion distribution at bedside. The purpose of this article is to review and discuss methodological and clinical aspects of EIT. Whereas

Predicting fluid-response, the heart of hemodynamic management: A model-based solution

Autor: Thomas Desaive, Christopher G. Pretty, J. Geoffrey Chase, Rachel Smith, Geoffrey M. Shaw

Publikováno v: Computers in Biology and Medicine. 139:104950

Background Intravenous fluid infusions are an important therapy for patients with circulatory shock. However, it is challenging to predict how patients’ cardiac stroke volume (SV) will respond, and thus identify how much fluids should be delivered,
