• Sometimes, sepsis , your body's response to blood infections that can lead to a dangerous drop in blood pressure and organ failure, can cause high cardiac output. (webmd.com)
  • The cardiac output represents the volume of blood that is delivered to the body, and is therefore an important factor in the determination of the effectiveness of the heart to deliver blood to the rest of the body, (i.e., determining heart failure, inadequate circulation, etc). (ebme.co.uk)
  • All these points are associated to distinct physiological events within the systolic part of the cardiac cycle, i.e., located after the QRS complex onset. (wikipedia.org)
  • In this review on cardiac output methods used in pharmacology, the Fick principle, indicator dilution techniques, arterial pulse contour analysis, ultrasound and bio-impedance are reviewed. (biomedsearch.com)
  • The European Society of Cardiology (ESC) defines cardiogenic shock as "evidence of tissue hypoperfusion induced by cardiac dysfunction after correction of preload. (psychiatryadvisor.com)
  • We evaluated the accuracy, precision, responsiveness, and reliability of NICOM for detecting cardiac output changes. (springer.com)
  • Cardiac output measured by NICOM had most often acceptable accuracy, precision, and responsiveness in a wide range of circulatory situations. (springer.com)
  • The NICOM® ICU (Intensive Care Unit) and CCU (Critical Care Unit) is a non-invasive Cardiac Output monitor based on Haemodynamic Reactance Mapping, intended for the measurement and display of Cardiac Output and ECG (electrocardiogram), both at rest and under medical tests. (medgadget.com)
  • In ICU, non-invasive Cardiac Output monitoring by the NICOM® provides haemodynamic information, which assists in diagnosis and therapy of heart patients by establishing the patient's baseline haemodynamic status for optimization of drug titration. (medgadget.com)
  • When CO increases in a healthy but untrained individual, most of the increase can be attributed to an increase in HR. Change of posture, increased sympathetic nervous system activity, and decreased parasympathetic nervous system activity can also increase cardiac output. (statemaster.com)
  • Increasing the heart rate effectively increases the cardiac output by increasing the number of cardiac volumes of blood released into the system. (ebme.co.uk)
  • Dark PM, Singer M (2004) The validity of trans-esophageal Doppler ultrasonography as a measure of cardiac output in critically ill adults. (springer.com)
  • Cardiac output measurement, by means of electrical velocimetry, may be able to determine optimum maternal position during gestation, labour and caesarean delivery, by preventing vena caval compression and maximising cardiac output and placental perfusion pressure. (thefreedictionary.com)
  • Because cardiac output is related to the quantity of blood delivered to various parts of the body, it is an important indicator of how efficiently the heart can meet the body's demands for perfusion. (wikipedia.org)
  • During exercise, an increase in heart rate is usually experienced, suggesting that as the cause of increased cardiac output and driving more blood to the muscles. (livestrong.com)
  • In people with heart failure, however, the continuous production of these hormones begins to stiffen the heart and blood vessel muscles and can decrease cardiac output. (livestrong.com)
  • The pattern of dye dilution curves and the cardiac output was studied in 29 healthy newborn infants during the first 26 hours of life by the method of Wood and his associates. (ahajournals.org)
  • Guyton's cardiac function and venous return curves provide a graphical solution to these equations. (ebme.co.uk)
  • As long as the heart is given a long enough diastole (resting phase), the effective volume that the heart outputs will increase. (ebme.co.uk)
  • A low cardiac output occurs when the pump function of the heart is compromised by an event such as a heart attack or when the blood volume is reduced by and event such as dehydration , or bleeding. (healthtap.com)
  • The diverse patient population included unstable patients in general, cardiac, and post-surgical intensive care settings. (medgadget.com)
  • These methods allow one to determine the amount of blood being delivered to the vasculature by the heart, and whether its output is sufficient to sustain the health of the patient. (ebme.co.uk)
  • Hi cardiac output could be caused by vitamin deficiencies, thyroid problems, multiple myeloma, paget's disease, arterio-venous fistulas and some other rare causes. (medhelp.org)
  • In an accompanying editorial, Christine T. Trieu, M.D., physician anesthesiologist, at the Ronald Reagan UCLA Medical Center, noted there are very few commercially available, precise cardiac output monitoring devices for infants and young children. (news-medical.net)
