  2. Hemodynamics - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics

    Hemodynamic monitoring is the observation of hemodynamic parameters over time, such as blood pressure and heart rate. Blood pressure can be monitored either invasively through an inserted blood pressure transducer assembly (providing continuous monitoring), or noninvasively by repeatedly measuring the blood pressure with an inflatable blood ...

  3. Virchow's triad - Wikipedia

    en.wikipedia.org/wiki/Virchow's_triad

    Stasis [2] The first category, alterations in normal blood flow, refers to several situations. These include venous stasis, long surgical operations, prolonged immobility (whilst on a long plane or car ride, bed bound during hospitalization), and varicose veins. The equivalence of Virchow's version and the modern version has been disputed. [5]

  4. Haemodynamic response - Wikipedia

    en.wikipedia.org/wiki/Haemodynamic_response

    When these calcium ion waves spread down the length of the astrocyte, phospholipase A (PLA 2) is activated which in turn mobilizes arachidonic acid. These two compounds are transported to the smooth muscle and there react with cytochrome P450 to make 20-hydroxyeicosatetraenoic acid (20-HETE), which acts through yet to-be-determined mechanisms ...

  5. Pressure–volume loop analysis in cardiology - Wikipedia

    en.wikipedia.org/wiki/Pressure–volume_loop...

    Several physiologically relevant hemodynamic parameters such as stroke volume, cardiac output, ejection fraction, myocardial contractility, etc. can be determined from these loops. To generate a PV loop for the left ventricle, the LV pressure is plotted against LV volume at multiple time points during a single cardiac cycle .

  6. Infarction - Wikipedia

    en.wikipedia.org/wiki/Infarction

    Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...

  7. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    This hemodynamic collapse results in poor blood flow to the brain and other organs, which if prolonged causes persistent damage. There are many different types of arrhythmias, but the ones most frequently recorded in sudden cardiac arrest are ventricular tachycardia and ventricular fibrillation .

  8. Hypovolemic shock - Wikipedia

    en.wikipedia.org/wiki/Hypovolemic_shock

    A substantial amount of blood loss to the point of hemodynamic compromise may occur in the chest, abdomen, or the retroperitoneum. [3] The thigh itself can hold up to 1 L to 2 L of blood. [3] Localizing and controlling the source of bleeding is of utmost importance to the treatment of hemorrhagic shock. [3]

  9. Syndrome of inappropriate antidiuretic hormone secretion

    en.wikipedia.org/wiki/Syndrome_of_inappropriate...

    Of the causes of medication induced syndrome of inappropriate antidiuresis, antidepressants (especially SSRIs) are the most common culprit. [2] Central nervous system (CNS) disorders or conditions may cause SIADH in 9% of cases, this includes subarachnoid hemorrhage (56% of CNS causes), pituitary surgery (35% of CNS causes), brain cancer ...
