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.

Cardiac output in 1998 [PDF]

Heart, 1998
Over 100 years ago Karl Ludwig stated that: The fundamental problems in the circulation derive from the fact that the supply of adequate amounts of blood to the organs of the body is the main purpose of the circulation while the pressures that are necessary to achieve it are of secondary importance; but the measurement of flow is difficult while that ...

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

Cardiorenal syndrome type I recovery following heart rate correction: Cardiac output is not only stroke volume

Clinical Case Reports, 2022
Bradyarrhymias can result in low cardiac output state despite having a normal left ventricular ejection fraction and stroke volume. Because cardiac output is defined as the product of heart rate and stroke volume, a low cardiac output state caused by ...

Lactate acidosis and cardiac output during initial therapeutic cooling in asphyxiated newborn infants.

PLoS ONE, 2019
AimWe hypothesized that compromised cardiac output in asphyxiated infants may influence on the rate of disappearance of lactate due to insufficient perfusion.MethodsThe study was a prospective, observational study, where infants with perinatal asphyxia ...

Cardiac Output Monitoring in Preterm Infants

Frontiers in Pediatrics, 2018
Maintaining optimal circulatory status is a key component of preterm neonatal care. Low-cardiac output (CO) in the preterm neonate leads to inadequate perfusion of vital organs and has been linked to a variety of adverse outcomes with heightened acute ...
