• systolic
  • Further analysis of the ideal cycle indicated that the end-systolic P-V relationship (ESPVR) is an approximation to the adiabatic P-V trajectory that primarily determines total energy consumption. (biomedsearch.com)
  • tension
  • Oxygen and air are received from cylinders or wall outlets, the gas is pressure reduced and blended according to the prescribed inspired oxygen tension (FiO2), accumulated in a receptacle within the machine, and delivered to the patient using one of many available modes of ventilations.

  • calcium
  • Calcium-sensitizing agents exert a positive inotropic action by increasing the sensitivity of the myocardial contractile apparatus to calcium. (ahajournals.org)
  • Levosimendan is a new myocardial calcium sensitizer that binds to troponin C. 9,10 Levosimendan has inotropic and vasodilator effects that have been shown to have beneficial short-term hemodynamic and clinical effects in patients with decompensated heart failure. (ahajournals.org)
  • Intracellular
  • Myocardial and hemodynamic effects of LY341311 were compared with dobutamine, a standard positive inotropic agent that acts via the β-receptor to increase intracellular cyclic AMP ( Tuttle and Mills, 1975 ). (aspetjournals.org)
  • capillary
  • Krogh model is a scientific model in the area mass transfer explaining concentration of molecular oxygen through a cylindrical capillary tube as a function of a changing position over the capillary tube's length. (wikipedia.org)
  • Krogh model is derived by applying Fick's laws of diffusion and the law of conservation of mass over a radial interval R c ≤ r ≤ R t {\displaystyle Rc\leq r\leq Rt} Although Krogh model is a good approximation, it underestimates oxygen consumption because the cylinder model does not include all the tissue surrounding the capillary.

  • tissue
  • Gaseous signaling molecules are gaseous molecules that are either synthesised internally (endogenously) in the organism, tissue or cell or are received by the organism, tissue or cell from outside (say, from the atmosphere or hydrosphere, as in the case of oxygen) and that are used to transmit chemical signals which induce certain physiological or biochemical changes in the organism, tissue or cell. (wikipedia.org)
  • The dead heart muscle is replaced by non-contractile fibrotic tissue, forming the myocardial scar. (wikipedia.org)
  • quiescence
  • The main goals of hypothermic cardioplegia are: Immediate and sustained electromechanical quiescence Rapid and sustained homogeneous myocardial cooling Maintenance of therapeutic additives in effective concentrations Periodic washout of metabolic inhibitors The most common procedure for accomplishing asystole is infusing cold cardioplegic solution into the coronary circulation.

  • nitric oxide
  • Nitric oxide, known as the 'endothelium-derived relaxing factor', or 'EDRF', is biosynthesized endogenously from L-arginine, oxygen, and NADPH by various nitric oxide synthase (NOS) enzymes. (wikipedia.org)
  • A particularly important intermediate in the chemical industry, nitric oxide forms in mixtures of nitrogen and oxygen at high temperatures, as found in combustion systems such as internal-combustion piston engines, gas turbines, furnaces, and boilers. (wikipedia.org)
  • When exposed to oxygen, nitric oxide is converted into nitrogen dioxide. (wikipedia.org)
  • In water, nitric oxide reacts with oxygen and water to form HNO2 or nitrous acid. (wikipedia.org)
  • The nitric oxide reacts with the ozone to produce oxygen and nitrogen dioxide, accompanied with emission of light (chemiluminescence): ·NO + O3 → NO2 + O2 + hν which can be measured with a photodetector. (wikipedia.org)
  • left
  • Dogs were anesthetized with isoflurane in oxygen and ventilated with a respirator after induction with acepromazine (0.03 mg/kg i.m.) and propofol (5.5 mg/kg i.v.). A left thoracotomy was performed through the fifth intercostal space under sterile technique. (aspetjournals.org)
