The aim of the study is to investigate the use of a new FDA-approved non-invasive bio-impedance cardiac monitor, ICON, to detect hemodynamic effects during sedation in children undergoing radiology procedures. The purpose of the study is to determine the ability of the ICON monitor to identify the anticipated and documented hemodynamic changes in children which occur in response to Dexmedetomidine sedation. The investigators postulate that if the ICON device can trend hemodynamic changes, if any, during dexmedetomidine (DEX) sedation in children the investigators can delineate changes in cardiac output, stroke volume, and systemic vascular resistance associated with observed changes in heart rate and blood pressure.

Cardiac output, the amount of blood pumped by the heart in one minute, will be measured in pediatric patients undergoing surgery involving cardiopulmonary bypass (CPB). Cardiac output will...
The purpose of the study is to evaluate the cardiac output changes after an intravenous bolus of ephedrine, phenylephrine, ondansetron or norepinephrine during a spinal anesthetic for a ce...
Accurate cardiac output determination is a commonly used and important index of myocardial performance. The thermodilution method using a pulmonary artery catheter is the most common appro...
Measurement of the cardiac output is one of the important hemodynamic monitoring tools in cardiac surgery. It helps determine the type of medications needed to maintain optimal hemodynamic...
Automated software analysis now allows for quick estimation of cardiac output from the echocardiographic 5-chamber view. This study will validate the automated software method against pulm...

Capstesia is an app for smartphones that can serve as a simple, accessible and affordable alternative to current advanced hemodynamic monitoring devices. The aim of this paper was to establish the deg...
What is the central question of this study? What is the role of heart muscle function in the increased output of remodelled, larger hearts? What is the main finding and its importance? The greater str...
A state of elevated cardiac output due to conditions of either increased hemodynamic demand or reduced cardiac oxygen output. These conditions may include ANEMIA; ARTERIOVENOUS FISTULA; THYROTOXICOSIS; PREGNANCY; EXERCISE; FEVER; and ANOXIA. In time, compensatory changes of the heart can lead to pathological form of high cardiac output and eventual HEART FAILURE.
A state of subnormal or depressed cardiac output at rest or during stress. It is a characteristic of CARDIOVASCULAR DISEASES, including congenital, valvular, rheumatic, hypertensive, coronary, and cardiomyopathic. The serious form of low cardiac output is characterized by marked reduction in STROKE VOLUME, and systemic vasoconstriction resulting in cold, pale, and sometimes cyanotic extremities.
A condition of fainting spells caused by heart block, often an atrioventricular block, that leads to BRADYCARDIA and drop in CARDIAC OUTPUT. When the cardiac output becomes too low, the patient faints (SYNCOPE). In some cases, the syncope attacks are transient and in others cases repetitive and persistent.
Compression of the heart by accumulated fluid (PERICARDIAL EFFUSION) or blood (HEMOPERICARDIUM) in the PERICARDIUM surrounding the heart. The affected cardiac functions and CARDIAC OUTPUT can range from minimal to total hemodynamic collapse.
A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
