  • By inducing ischaemia, changes in renal vascular resistance (RVR) may contribute substantially to the extent of nephrotoxic injury. (springer.com)

  • In the present study, we investigated changes in mesenteric, renal, and hindquarter vascular resistance during the pressor response produced by bilateral carotid occlusion (BCO) in conscious, freely moving normal and denervated (aortic, carotid, or both) rats. (ahajournals.org)
  • In control normal rats, the increase in mean arterial pressure (MAP) during early and late responses (37 +/- 4 and 21 +/- 2 mm Hg, respectively) was related to increased renal (125 +/- 12% and 45 +/- 10%) and mesenteric (38 +/- 13% and 41 +/- 5%) but not hindquarter (14 +/- 4% and 8 +/- 7%) vascular resistance. (ahajournals.org)
  • Sinoaortic-denervated rats showed a greater MAP increase (34 +/- 4 mm Hg) during late response and a reduced increase in renal vascular resistance (46 +/- 6%) during early response. (ahajournals.org)
  • mmHg
  • The conversion between these units is: 1 mmHG ⋅ min L ( HRUs ) = 8 MPa ⋅ s m 3 = 80 dyn ⋅ sec cm 5 {\displaystyle 1\,{\frac {{\text{mmHG}}\cdot {\text{min}}}{\text{ L }}}({\text{HRUs}})=8\,{\frac {{\text{MPa}}\cdot {\text{s}}}{{\text{m}}^{3}}}=80\,{\frac {{\text{dyn}}\cdot {\text{sec}}}{{\text{cm}}^{5}}}} The basic tenet of calculating resistance is that flow is equal to driving pressure divided by resistance.

  • vessel
  • Vasomotion could also be a mechanism of increasing the reactivity of a blood vessel by avoiding the "latch state", a low ATP cycling state of prolonged force generation common in vascular smooth muscle. (wikipedia.org)
  • Diseases
  • Indications are amongst others: Connective tissue weakness, overacidification, cellulite and spider veins, injuries (e.g. bruises or sports injuries), vascular diseases, oedemata and ulcers. (wikipedia.org)
  • Pressure
  • In the current study, 18 obese subjects had measurements of blood pressure, forearm blood flow, forearm vascular resistance, and both basal platelet [Ca2+]i and [Ca2+]i responses to vasopressin during 12 weeks on a very low calorie (3,360 kJ, or 800 kcal) diet. (ahajournals.org)
  • The secondary endpoints are the percentage change in mean pulomanry artery pressure (PAP), systemic vascular resistance (SVR) and mean arterial pressure (MAP). (clinicaltrials.gov)
  • Although it ejects the same blood volume as the LV, the RV generates about one-sixth of its work and pressure, because the pulmonary vascular resistance is only about 15% of systemic vascular resistance (SVR). (thefreedictionary.com)
  • The above equation contains a numerical constant to compensate for the units used, but is conceptually equivalent to the following: R = Δ P Q {\displaystyle R={\frac {\Delta P}{Q}}} where R is the pulmonary vascular resistance (fluid resistance), ΔP is the pressure difference across the pulmonary circuit, and Q is the rate of blood flow through it. (wikipedia.org)
  • Vascular compliance is determined by the muscle tone in the smooth muscle tissue of the tunica media and the elasticity of the elastic fibers there, but the muscle tone is subject to continual homeostatic changes by hormones and cell signaling molecules that induce vasodilation and vasoconstriction to keep blood pressure and blood flow within reference ranges. (wikipedia.org)
  • airway resistance the opposition of the tissues of the air passages to air flow: the mouth-to-alveoli pressure difference divided by the rate of air flow. (thefreedictionary.com)
  • It reduces mean arterial blood pressure by decreasing systemic vascular resistance. (wikipedia.org)
  • This is because they can decrease vascular resistance and decrease pressure. (wikipedia.org)
  • patients
  • In a retrospective chart review of patients who underwent PTE at UCSD between July 2010 and June 2013, Crouch found that 64 subjects had pre-operative pulmonary resistance values (PVRs) less than 300 dyn∙/cm5 and 355 patients had PVRs above 300dyn∙/cm5. (eurekalert.org)
  • Units
  • This is numerically equivalent to hybrid resistance units (HRU), also known as Wood units (in honor of Paul Wood, an early pioneer in the field), frequently used by pediatric cardiologists. (wikipedia.org)
  • smooth
  • Intracellular calcium (Ca2+) concentration exhibits periodic oscillations in vascular smooth muscle cells. (wikipedia.org)
  • When patch clamp recordings are conducted, depolarization occurs in the endothlial layer at the same time as the underlying vascular smooth muscle. (wikipedia.org)
  • time
  • Echocardiographic ratio of peak tricuspid regurgitant velocity to the right ventricular outflow tract time-velocity integral (TRV/TVI rvot) was presented as a reliable non-invasive method of estimating pulmonary vascular resistance (PVR). (7thspace.com)
  • treatment
  • The Intermittent Vacuum Therapy (IVT) is a treatment conducted in case of venous and arterial issues as well as in rehabilitation (after sports injuries and vascular complaints). (wikipedia.org)
  • Male
  • Incomplete androgen resistance is any of various forms less than the complete type, manifested by a male phenotype with various degrees of ambiguous genitalia such as hypospadias and a small vaginal pouch, a hooded phallus, or a bifid scrotum that may or may not contain gonads.
