• mmHg
  • Heart rate (range: 68-75 beat/min), mean arterial pressure (80-90 mmHg), CVP (7-10 mmHg), SpO2 (79-90 percent), ScvO2 (57-70 percent), and ExO2 (21-30 percent) remained stable during epidural anesthesia and transvaginal sterilization. (biomedsearch.com)
  • The purpose of the present study was to determine the central retinal venous pressure (CRVP) in patients with retinal vascular occlusions using a contact lens ophthalmodynamometer calibrated in mmHg. (arvojournals.org)
  • CRVP in central retinal vascular occlusions (CRAO and CRVO) was higher than in branch retinal vascular occlusions (BRAO and BRVO): 44.4±13.5 mmHg and 29.9±12.4mmHg respectively (P=0.026). (arvojournals.org)
  • Compliance is calculated using the following equation, where ΔV is the change in volume (mL), and ΔP is the change in pressure (mmHg): C = Δ V Δ P {\displaystyle C={\frac {\Delta V}{\Delta P}}} Physiologic compliance is generally in agreement with the above and adds dP/dt as a common academic physiologic measurement of both pulmonary and cardiac tissues.

  • The blood pressure inside the umbilical vein is approximately 20 mmHg. (wikipedia.org)
  • collapsibility
  • Ultrasound can be utilized to assess a persons intravascular volume status and response to intravenous fluid therapy by measuring the size and respiratory change in the diameter of the IVC, including the assessment of central venous collapsibility as a more standardized mesure of intravascular volume status. (wikipedia.org)
  • clinical
  • A high venous outflow resistance seems to be present in both eyes and might therefore be a valuable clinical predictor. (arvojournals.org)
  • When reviewing the clinical data, one of the residents referred to the central venous pressure [CVP] as a ' random number generator . (pulmccm.org)
  • However, it may be seen in normotensive patients (with normal blood pressure) before the appearance of clinical hypertension. (wikipedia.org)
  • respectively
  • and the Interior and Northern BC Communications Centre (INBCCC) deploys resources to the remainder of the province, including the southern interior (Okanagan, Cariboo & Kootenays) and northern BC (Skeena, Northern Interior & Peace Regions, representing west-central, east-central and northern areas of the province, respectively). (wikipedia.org)
  • internal jugu
  • AJR is a test for measuring jugular venous pressure (JVP) through the distention of the internal jugular vein. (wikipedia.org)
  • The clinician presses firmly over either the right upper quadrant of the abdomen (i.e., over the liver) or over the center of the abdomen for 10 seconds with a pressure of 20 to 35 mm Hg while observing the swelling of the internal jugular vein in the neck and also observing to be sure the patient does not perform a Valsalva maneuver. (wikipedia.org)
  • fluid
  • Therapeutic plasma exchange is an apheresis modality in which plasma is separated from the blood cellular components ex vivo, discarded, and replaced with an isosmotic fluid (most commonly 5% albumin) to maintain appropriate oncotic pressure in the patient. (readbyqxmd.com)
  • The pressure of the cerebrospinal fluid. (thefreedictionary.com)
  • they are functions not merely of the fluid mechanics of pressure and tissue elasticity but also of active homeostatic regulation with hormones and cell signaling, in which the body produces endogenous vasodilators and vasoconstrictors to modify its vessels' compliance. (wikipedia.org)
  • If a lumbar puncture is performed, it will show normal cerebral spinal fluid and cell counts but an increase in pressure. (wikipedia.org)
  • Venous access is any kind of way to access the bloodstream through the veins, either to administer intravenous therapy (medication, fluid), parenteral nutrition, to obtain blood for analysis, or of blood-based treatments such as dialysis or apheresis. (wikipedia.org)
  • Sequestration of fluid and electrolytes, as revealed by decreased central venous pressure, may cause electrolyte disturbances, as well as significant hypovolemia, possibly leading to shock and acute kidney failure. (wikipedia.org)
  • Invasive
  • For invasive pressure monitoring in patients undergoing cardiovascular surgery, we use a color-coded multitransducer system with a single pressurized bag of normal saline for line rinsing. (asahq.org)
  • return
  • Together the stressed venous volume and venous compliance form the mean circulatory filling pressure which is the pressure head for venous return to the right heart [3- (pulmccm.org)
  • Importantly, the opposite is also true - venodilation, volume loss, sympatholysis [e.g. relief of hypoxemia, sedation] tend to lower the pressure head for venous return and consequently lower CVP. (pulmccm.org)
  • But the strings of venous return are only half of the story because cardiac contractility, afterload, heart rate, rhythm and valve function are another group of strings serving to pull the CVP up or down. (pulmccm.org)
  • While Arthur Guyton described in great detail the determinants of venous return, perhaps his greatest contribution was a graphical analysis that superimposed both the venous return function and cardiac function onto a single graph [3, (pulmccm.org)
  • This is not to be confused with stage 4 of the Valsalva maneuver, in which the release of high intrathoracic pressure previously generated by forced expiration against a closed glottis, now restores venous return and cardiac output into a vasoconstricted circulation, stimulating the vagus nerve and leading to a slowing of the heart, or bradycardia. (wikipedia.org)
  • oncotic pressure
  • Chronic diarrhea is almost always seen with lymphangiectasia, but most other signs are linked to low blood protein levels (hypoproteinemia), which causes low oncotic pressure. (wikipedia.org)
  • compliance
  • When the CVP falls below intra-abdominal pressure, the IVC will tend to collapse and when the CVP rises above the intra-abdominal pressure the IVC will tend to distend, both as a function of IVC compliance . (pulmccm.org)
  • Compliance is the ability of a hollow organ (vessel) to distend and increase volume with increasing transmural pressure or the tendency of a hollow organ to resist recoil toward its original dimensions on application of a distending or compressing force. (wikipedia.org)
  • This physically means that blood vessels with a higher compliance deform easier than lower compliance blood vessels under the same pressure and volume conditions. (wikipedia.org)
  • Venous compliance is approximately 30 times larger than arterial compliance. (wikipedia.org)
  • Pressure stockings are sometimes used to externally reduce compliance, and thus keep blood from pooling in the legs. (wikipedia.org)
  • Compliance, in simple terms, is the degree to which a container experiences pressure or force without disruption. (wikipedia.org)
