Air displacement pipettePlethysmographEthernet flow control: Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The first flow control mechanism, the PAUSE frame, was defined by the IEEE 802.Vasodilation: Vasodilation (or vasodilatation) refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles.Sodium nitroprussideCheyne–Stokes respirationSuperficial vein: Superficial vein is a vein that is close to the surface of the body. This differs from deep veins that are far from the surface.DimefoxHyperaemiaPlateau pressure: Plateau pressure (PPLAT) is the pressure applied to small airways and alveoli during positive-pressure mechanical ventilation.Morgan, Edward G.Blood vessel: The blood vessels are the part of the circulatory system that transports blood throughout the human body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.Optoelectronic plethysmography: Optoelectronic plethysmography (OEP) is a method to evaluate ventilation through an external measurement of the chest wall surface motion.MethacholinePerforator vein: Perforator veins are so called because they perforate the deep fascia of muscles, to connect the superficial veins to the deep veins where they drain.http://www.Post-thrombotic syndrome: Post-thrombotic syndrome (PTS), also called postphlebitic syndrome and venous stress disorder is a medical condition that may occur as a long-term complication of deep vein thrombosis (DVT).Aortic pressure: Central aortic blood pressure (CAP or CASP) is the blood pressure at the root of aorta. Studies have shown the importance of central aortic pressure and its implications in assessing the efficacy of antihypertensive treatment with respect to cardiovascular risk factors.Superficial velocity: Superficial velocity (or superficial flow velocity), in engineering of multiphase flows and flows in porous media, is a hypothetical (artificial) flow velocity calculated as if the given phase or fluid were the only one flowing or present in a given cross sectional area. Other phases, particles, the skeleton of the porous medium, etc.Endothelial activation: Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis, among others.Impedance phlebographyPhlegmasia cerulea dolens: Phlegmasia cerulea dolens (literally: painful blue edema) is an uncommon severe form of deep venous thrombosis which results from extensive thrombotic occlusion (blockage by a thrombus) of the major and the collateral veins of an extremity. It is characterized by sudden severe pain, swelling, cyanosis and edema of the affected limb.Endothelial dysfunction: In vascular diseases, endothelial dysfunction is a systemic pathological state of the endothelium (the inner lining of blood vessels) and can be broadly defined as an imbalance between vasodilating and vasoconstricting substances produced by (or acting on) the endothelium. Normal functions of endothelial cells include mediation of coagulation, platelet adhesion, immune function and control of volume and electrolyte content of the intravascular and extravascular spaces.Interbeat interval: Interbeat interval is a scientific term used in the study of the mammalian heart.Spirometer: A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs.Air sensitivity: Air sensitivity is a term used, particularly in chemistry, to denote the reactivity of chemical compounds with some constituent of air. Most often, reactions occur with atmospheric oxygen (O2) or water vapor (H2O),Handling and Storage of Air-Sensitive Reagents, Technical Bulletin AL-134, Sigma-Aldrich although reactions with the other constituents of air such as carbon monoxide (CO), carbon dioxide (CO2), and nitrogen (N2) are also possible.Pratt Test: The Pratt Test is a simple test to check for deep vein thrombosis in the leg. It involves having the patient lie supine with the leg bent at the knee, grasping the calf with both hands and pressing on the popliteal vein in the proximal calf.Lung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.Riding-like sittingExpiratory apnea: Expiratory apnea is a voluntary condition performed by a patient during a doctor's examination. By breathing out and then holding one's breath, it gets easier for the doctor to perform an auscultation of the heart with a stethoscope.Intravascular volume status: In medicine, intravascular volume status refers to the volume of blood in a patient's circulatory system, and is essentially the blood plasma component of the overall volume status of the body, which otherwise includes both intracellular fluid and extracellular fluid. Still, the intravascular component is usually of primary interest, and volume status is sometimes used synonymously with intravascular volume status.Helium-3Femoral vein: In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor canal (also known as Hunter's canal) and is a continuation of the popliteal vein.Permissive hypercapnia: Permissive hypercapnia is hypercapnia, (i.e.Tour SignalNitroglycerinMayer waves: Mayer waves are cyclic changes or waves in arterial blood pressure brought about by oscillations in baroreceptor and chemoreceptor reflex control systems. The waves are seen both in the ECG and in continuous blood pressure curves and have a frequency about 0.Generalizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.Five Fingers GroupCompliance (physiology): 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. It is the reciprocal of "elastance", hence elastance is a measure of the tendency of a hollow organ to recoil toward its original dimensions upon removal of a distending or compressing force.Bronchoconstriction: Bronchoconstriction is the constriction of the airways in the lungs due to the tightening of surrounding smooth muscle, with consequent coughing, wheezing, and shortness of breath.Concentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.Unna's boot: In medicine, an Unna boot is a special gauze (usually 4 inches wide and 10 yards long) bandage, which can be used for the treatment of venous stasis ulcers and other venous insufficiencies of the leg. It can also be used as a supportive bandage for sprains and strains of the foot, ankle and lower leg.Non-pneumatic anti-shock garment: The non-pneumatic anti-shock garment (NASG) is a low-technology first-aid device used to treat hypovolemic shock. Its efficacy for reducing maternal deaths due to obstetrical hemorrhage is being researched.Hypoxic hypoxia: Hypoxic hypoxia is a result of insufficient oxygen available to the lungs. A blocked airway, a drowning or a reduction in partial pressure (high altitude above 10,000 feet) are examples of how lungs can be deprived of oxygen.Placebo-controlled study: Placebo-controlled studies are a way of testing a medical therapy in which, in addition to a group of subjects that receives the treatment to be evaluated, a separate control group receives a sham "placebo" treatment which is specifically designed to have no real effect. Placebos are most commonly used in blinded trials, where subjects do not know whether they are receiving real or placebo treatment.Clinical death: Clinical death is the medical term for cessation of blood circulation and breathing, the two necessary criteria to sustain human and many other organisms' lives. It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest.BradypneaDietmar Wittmann: Dietmar H. Wittmann, M.Photoplethysmogram variability: The photoplethysmogram (PPG) measurement made at a peripheral site, such as the finger, ear or forehead represents the volume of blood in the vessel at the site of measurement. The PPG signal consists of pulses that reflect the change in vascular blood volume with each cardiac beat.Tilt table test: A tilt table test, occasionally called upright tilt testing, is a medical procedure often used to diagnose dysautonomia or syncope. Patients with symptoms of dizziness or lightheadedness, with or without a loss of consciousness (fainting), suspected to be associated with a drop in blood pressure or positional tachycardia are good candidates for this test.Diaphragmatic excursion: Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing.HypertensionTourniquet: A tourniquet is a constricting or compressing device, specifically a bandage, used to control venous and arterial circulation to an extremity for a period of time. Pressure is applied circumferentially upon the skin and underlying tissues of a limb; this pressure is transferred to the walls of vessels, causing them to become temporarily occluded.External iliac vein: The external iliac veins are large veins that connect the femoral veins to the common iliac veins. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins).Ventolin (EP): "Ventolin" is a piece of electronic music composed by Cornish musician Richard D James. It is noted for its harsh, abrasive sound.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingDistributing artery: A distributing artery (or muscular artery) is a medium-sized artery that draw blood from an elastic artery and branch into "resistance vessels" including small arteries and arterioles. In contrast to the mechanism elastic arteries use to store energy generated by the heart's contraction, distributing arteries contain layers of smooth muscle.
