Lying (position)Riding-like sittingTilt 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.Trendelenburg position: In the Trendelenburg position, the body is laid flat on the back (supine position) with the feet higher than the head by 15-30 degrees, in contrast to the reverse Trendelenburg position, where the body is tilted in the opposite direction. This is a standard position used in abdominal and gynecological surgery.Interbeat interval: Interbeat interval is a scientific term used in the study of the mammalian heart.Orthostatic hypotensionPercutaneous nephrostomyFujiyama (roller coaster)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.Cheyne–Stokes respirationDimefoxIndoraminAntonio Maria ValsalvaHair-grooming syncope: Hair-grooming syncope (also known as hair-combing syncope) is a form of syncope (a fainting disorder) associated with combing and brushing one's hair. It is most typically seen in children aged five to sixteen.Baroreflex: The baroreflex or baroreceptor reflex is one of the body's homeostatic mechanisms that helps to maintain blood pressure at nearly constant levels. The baroreflex provides a rapid negative feedback loop in which an elevated blood pressure reflexively causes the heart rate to decrease and also causes blood pressure to decrease.Transpulmonary pressure: Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients.Gyromancy: Gyromancy is a method of divination in which a person spins around inside or walks the circumference of a circle drawn on the ground, the perimeter of which is marked with the letters of an alphabet. The divination is inferred from the letter at the position where the person either stumbles or falls across the circle’s edge.Voluntary Parenthood League: The Voluntary Parenthood League (VPL) was an organization that advocated for contraception during the birth control movement in the United States. The VPL was founded in 1919 by Mary Dennett.Vasovagal responseCardiac function curve: A cardiac function curve is a graph showing the relationship between right atrial pressure (x-axis) and cardiac output (y-axis).Plateau pressure: Plateau pressure (PPLAT) is the pressure applied to small airways and alveoli during positive-pressure mechanical ventilation.Morgan, Edward G.Sudden unexpected death syndromeBrachycephalic syndrome: Brachycephalic syndrome is a pathological condition affecting short nosed dogs and cats which leads to severe respiratory distress. There are four different anatomical abnormalities that contribute to the disease, all of which occur more commonly in brachycephalic breeds: an elongated soft palate, stenotic nares, a hypoplastic trachea, and everted laryngeal saccules (a condition which occurs secondarily to the other abnormalities).Acute esophageal necrosisArteriovenous oxygen difference: The arteriovenous oxygen difference, or a-vO2 diff, is the difference in the oxygen content of the blood between the arterial blood and the venous blood. It is an indication of how much oxygen is removed from the blood in capillaries as the blood circulates in the body.Non-rapid eye movement sleepOptoelectronic plethysmography: Optoelectronic plethysmography (OEP) is a method to evaluate ventilation through an external measurement of the chest wall surface motion.Isbrand van Diemerbroeck: Isbrand van Diemerbroeck (also Ijsbrand or Ysbrand) (13 December 1609 – 16 November 1674) was a Dutch physician, anatomist, and professor.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.Costovertebral angleDiaphragmatic excursion: Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing.Lung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingMattress protector: A mattress protector is an item of removable bedding that sits on top of or encases a mattress to provide protection to the mattress. Some mattress protectors also provide protection to the individual sleeping on the mattress from allergens and irritants such as dust mites, bed bugs, mold, and dead skin (like dandruff).Iron Lung (band)List of countries by carbon dioxide emissionsAir displacement pipetteSentinel loop: A sentinel loop is a sign seen on a radiograph that indicates localized ileus from nearby inflammation. Simply put, it is the dilatation of a segment of large or small intestine.Automated ECG interpretation: Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.Esophageal motility disorder: An esophageal motility disorder is any medical disorder causing difficulty in swallowing, regurgitation of food and a spasm-type pain which can be brought on by an allergic reaction to certain foods. The most prominent one is dysphagia.Ethernet 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.Coles PhillipsSuperficial 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.Steel tongue drum: A steel tongue drum, tank drum or hank drum is a round steel slit/tongue drum originally fashioned from a propane tank.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.Obstructive sleep apneaBlood 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.Spinal anaesthesia: Spinal anaesthesia (or spinal anesthesia), also called spinal analgesia, spinal block or subarachnoid block (SAB), is a form of regional anaesthesia involving injection of a local anaesthetic into the subarachnoid space, generally through a fine needle, usually 9 cm long (3.5 inches).Peak inspiratory pressure: Peak inspiratory pressure (PIP) is the highest level of pressure applied to the lungs during inhalation. In mechanical ventilation the number reflects a positive pressure in centimeters of water pressure (cmH2O).Intraocular pressureImbert-Fick law: The Imbert-Fick "law" was invented by Hans Goldmann (1899–1991) to give his newly marketed tonometer (with the help of the Haag-Streit Company) a quasi-scientific basis; it is mentioned in the ophthalmic and optometric literature, but not in any books of physics. According to Goldmann,Goldmann H.PolysomnographyJugular venous pressureTreadmill: A treadmill is a device generally for walking or running while staying in the same place. Treadmills were introduced before the development of powered machines, to harness the power of animals or humans to do work, often a type of mill that was operated by a person or animal treading steps of a treadwheel to grind grain.Infant respiratory distress syndromeGas analysis: Gas analysis could refer to any of the following:Sphygmomanometer: A sphygmomanometer ( ), blood pressure meter, blood pressure monitor or blood pressure gauge (also referred to as a sphygmometerAs the etymology indicates, this should have the somewhat different connotation of 'a gauge to measure pulse', whereas the main function is actually to measure pressure.) is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, and a mercury or mechanical manometer to measure the pressure.High-intensity interval training: High-intensity interval training (HIIT), also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is an enhanced form of interval training, an exercise strategy alternating short periods of intense anaerobic exercise with less-intense recovery periods. HIIT is a form of cardiovascular exercise.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.Demodulation: Demodulation is the act of extracting the original information-bearing signal from a modulated carrier wave. A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave.Dense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.Dietmar Wittmann: Dietmar H. Wittmann, M.Apnea–hypopnea index: The Apnea–Hypopnea Index or Apnoea–Hypopnoea Index (AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea and hypopnea events per hour of sleep.
