• jugular
  • The jugular venous pulsation has a biphasic waveform. (wikipedia.org)
  • The term "hepatojugular reflux" was previously used as it was thought that compression of the liver resulted in "reflux" of blood out the hepatic sinusoids into the great veins[disambiguation needed], thereby elevating right atrial pressure and visualized as jugular venous distention. (wikipedia.org)
  • arterial
  • In synchronization with each cardiac cycle, obtained with an integrated 3-lead ECG, the cuffs are sequentially inflated from the calves to the buttocks during diastole to produce an arterial retrograde flow towards the aortic root to increase coronary blood flow. (ieecps.org)
  • There are a number of clinical methods to measure cardiac output, ranging from direct intracardiac catheterization to non-invasive measurement of the arterial pulse. (wikipedia.org)
  • citation needed] Patent foramen ovale in underwater divers is considered a risk factor for arterial gas embolism due to shunt of what would otherwise be asymptomatic venous bubbles into the systemic arteries. (wikipedia.org)
  • atrial
  • The upward deflections are the "a" (atrial contraction), "c" (ventricular contraction and resulting bulging of tricuspid into the right atrium during isovolumetric systole) and "v" = venous filling The downward deflections of the wave are the "x" (the atrium relaxes and the tricuspid valve moves downward) and the "y" descent (filling of ventricle after tricuspid opening). (wikipedia.org)
  • The loss of the atrial kick due to atrial fibrillation ( i.e. blood cannot flow into the left ventricle thus accumulating in the left atrium ) can cause a precipitous decrease in cardiac output and sudden congestive heart failure. (wikipedia.org)

  • output
  • quantium Medical Cardiac Output (qCO) uses impedance cardiography in a simple, continuous, and non-invasive way to estimate the Cardiac output (CO) and other hemodynamic parameters such as the Stroke Volume (SV) and Cardiac index (CI). (wikipedia.org)
  • The assessment of Cardiac Output (CO) is important because it reveals the main cardiac function: the supply of blood to tissues. (wikipedia.org)
  • Cardiac output (CO, also denoted by the symbols Q {\displaystyle Q} and Q ˙ c {\displaystyle {\dot {Q}}_{c}} ), is a term used in cardiac physiology that describes the volume of blood being pumped by the heart, in particular by the left or right ventricle, per unit time. (wikipedia.org)
  • Values for cardiac output are usually denoted as L/min. (wikipedia.org)
  • 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)
  • Cardiac output is a global blood flow parameter of interest in hæmodynamics, the study of the flow of blood. (wikipedia.org)
  • The factors affecting stroke volume and heart rate also affect cardiac output. (wikipedia.org)
  • This is especially important during mechanical ventilation, in which cardiac output can vary by up to 50%[citation needed] across a single respiratory cycle. (wikipedia.org)
  • Cardiac output should therefore be measured at evenly spaced points over a single cycle or averaged over several cycles. (wikipedia.org)
  • Two-dimensional (2D) ultrasound and Doppler measurements are used together to calculate cardiac output. (wikipedia.org)
  • The result is then multiplied by the heart rate (HR) to obtain cardiac output. (wikipedia.org)

  • High-output heart failure can occur when there is an increased cardiac output. (wikipedia.org)

  • increases
  • This inflation action also increases venous return, increasing blood volume to the ventricles and raises cardiac ouput. (ieecps.org)
  • Physiologically, this is a consequence of the Frank-Starling mechanism as inspiration decreases the thoracic pressure and increases blood movement into the heart (venous return), which a healthy heart moves into the pulmonary circulation. (wikipedia.org)
  • The " v " wave corresponds to Venous filling when the tricuspid valve is closed and venous pressure increases from venous return - this occurs during and following the carotid pulse. (wikipedia.org)
  • arrest
  • Nitrous oxide is combustible and has been associated with sudden cardiac arrest. (blogs.com)
  • The literature suggests that an increase in heart rate is relatively common and that cardiac dysrhythmias or cardiac arrest may occur, but are unlikely. (blogs.com)
  • Heart failure is not the same as myocardial infarction (in which part of the heart muscle dies) or cardiac arrest (in which blood flow stops altogether). (wikipedia.org)
  • Targeted temperature management improves survival and brain function following resuscitation from cardiac arrest. (wikipedia.org)
  • Evidence supports its use following certain types of cardiac arrest in which an individual does not regain consciousness. (wikipedia.org)
  • Targeted temperature management may be used in the following conditions: The 2013 ILCOR and 2010 American Heart Association guidelines support the use of cooling following resuscitation from cardiac arrest. (wikipedia.org)
  • These recommendations were largely based on two trials from 2002 which showed improved survival and brain function when cooled to 32-34 °C (90-93 °F) after cardiac arrest. (wikipedia.org)
  • it appears cooling is effective because it prevents fever, a common complication seen after cardiac arrest. (wikipedia.org)
  • pacemaker
  • Sometimes, depending on the cause, an implanted device such as a pacemaker or an implantable cardiac defibrillator may be recommended. (wikipedia.org)
  • circulation
  • Inert gas bubbles arising from decompression are generally formed in the venous side of the systemic circulation, where inert gas concentrations are highest, these bubbles are generally trapped in the capillaries of the lungs where they will usually be eliminated without causing symptoms. (wikipedia.org)
  • Small amounts of air often get into the blood circulation accidentally during surgery and other medical procedures (for example, a bubble entering an intravenous fluid line), but most of these air emboli enter the veins and are stopped at the lungs, and thus a venous air embolism that shows any symptoms is very rare. (wikipedia.org)
  • arteries
  • Breathing gas introduced into the venous system of the lungs due to pulmonary barotrauma will not be trapped in the alveolar capillaries, and will consequently be circulated to the rest of the body through the systemic arteries, with a high risk of embolism. (wikipedia.org)

  • In 1989, after completing general surgery training at the Brigham, and in preparation for cardiac surgery training, Burke spent a year as a research fellow at the Massachusetts Institute of Technology, in the Spectroscopy Laboratory, under Michael Stephen Feld, PhD. Burke developed the idea that Laser-induced fluorescence spectroscopy could be used to diagnose rejection in transplanted cardiac tissue, thereby avoiding the need for traumatic biopsies. (wikipedia.org)
  • pressure
