Effect of Exercise-Induced Reductions in Blood Volume on Cardiac Output and Oxygen Transport Capacity

Frontiers in Physiology, 2021
We wanted to demonstrate the relationship between blood volume, cardiac size, cardiac output and maximum oxygen uptake (V.O2max) and to quantify blood volume shifts during exercise and their impact on oxygen transport.

The effect of positive end-expiratory pressure on cardiac output and oxygen delivery during cardiopulmonary resuscitation

Intensive Care Medicine Experimental, 2020
Background Positive end-expiratory pressure (PEEP) is used to optimize oxygenation by preventing alveolar collapse. However, PEEP can potentially decrease cardiac output through cardiopulmonary interactions.

The effects on arterial haemoglobin oxygen saturation and on shunt of increasing cardiac output with dopamine or dobutamine during one-lung ventilation [PDF]

, 2004
Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsTheoretically, if the cardiac output were increased in the presence of a given intrapulmonary shunt, the arterial saturation should improve as the ...

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Antiarrhythmic and proarrhythmic effects of subcutaneous nerve stimulation in ambulatory dogs [PDF]

, 2019
Background High output subcutaneous nerve stimulation (ScNS) remodels the stellate ganglia and suppresses cardiac arrhythmia. Objective To test the hypothesis that long duration low output ScNS causes cardiac nerve sprouting, increases plasma ...

A Narrative Review of Cardiac Output Measurement in Cardiac Surgery

Archives of Anesthesia and Critical Care, 2023
Continuous monitoring of the cardiovascular system and control of the changes affecting it is a constant challenge for the surgical team. The need to control the condition of the heart and better understand its condition is raised in the topic of ...

Lower Cardiac Output Relates to Longitudinal Cognitive Decline in Aging Adults

Frontiers in Psychology, 2020
BackgroundSubclinical reductions in cardiac output correspond to lower cerebral blood flow (CBF), placing the brain at risk for functional changes.ObjectivesThis study aims to establish the consequences of reduced cardiac output on longitudinal cognitive
