It is represented by the number of apnea and hypopnea events per hour of sleep.Central sleep apnea: Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds, either intermittently or in cycles and is usually associated with a reduction in blood oxygen saturation. It is a collective term referring to two breathing disorders: Cheyne-Stokes respiration and periodic breathing.PolysomnographyContinuous positive airway pressure: Continuous positive airway pressure (CPAP) is a form of positive airway pressure ventilator, which applies mild air pressure on a continuous basis to keep the airways continuously open in a patient who is unable to breathe spontaneously on his or her own. It is an alternative to positive end-expiratory pressure (PEEP).Brachycephalic 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).DimefoxPalatine uvula: The palatine uvula, usually referred to as simply the uvula , is a conic projection from the posterior edge of the middle of the soft palate, composed of connective tissue containing a number of racemose glands, and some muscular fibers (musculus uvulae).Ten Cate's Oral Histology, Nanci, Elsevier, 2007, page 321Mandibular advancement splintNon-rapid eye movement sleepNasal EPAPMicrosleepAdenoidectomyCheyne–Stokes respirationHypoxic 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.Nellcor: Nellcor is a brand of pulse oximetry systems sold by the Medtronic Corporation, following its acquisition of Covidien.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.Arteriovenous 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 depicted a sprightly priest, originally played by Antony Sher, who travelled around the plague-affected villages of 14th century France with a band of fools, known as God's Zanies, offering holy assistance.Cephalogram: A cephalogram is an X-ray of the craniofacial area. A cephalometric analysis could be used as means for measuring growth in children.Stylohyoid muscle: The stylohyoid muscle is a slender muscle, lying anterior, and superior of the posterior belly of the digastric muscle. It shares this muscle's innervation by the facial nerve, and functions to draw the hyoid bone backwards and elevate the tongue.Hypocapnia: Hypocapnia or hypocapnea also known as hypocarbia, sometimes incorrectly called acapnia, is a state of reduced carbon dioxide in the blood. Hypocapnia usually results from deep or rapid breathing, known as hyperventilation.HypoventilationQRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.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.Mouth breathingPharynx: The pharynx (plural: pharynges) is an organ found in vertebrates and invertebrates, though the structure is not universally the same across the species. In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system.Gas analysis: Gas analysis could refer to any of the following:Hypoglossal trigone: In the upper part of the medulla oblongata, the hypoglossal nucleus approaches the rhomboid fossa, where it lies close to the middle line, under an eminence named the hypoglossal trigone.Quantitative electroencephalography: Quantitative electroencephalography (QEEG) is a field concerned with the numerical analysis of electroencephalography data and associated behavioral correlates.Hyperventilation syndromeTemporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingAging movement control: Normal aging movement control in humans is about the changes on the muscles, motor neurons, nerves, sensory functions, gait, fatigue, visual and manual responses, in men and women as they get older but who do not have neurological, muscular (atrophy, dystrophy...) or neuromuscular disorder.Nested case-control study: A nested case control (NCC) study is a variation of a case-control study in which only a subset of controls from the cohort are compared to the incident cases. In a case-cohort study, all incident cases in the cohort are compared to a random subset of participants who do not develop the disease of interest.Midnight: Midnight is the transition time period from one day to the next: the moment when the date changes. In ancient Roman timekeeping, midnight was halfway between sunset and sunrise, varying according to the seasons.ElectrooculographyComorbidity: In medicine, comorbidity is the presence of one or more additional disorders (or diseases) co-occurring with a primary disease or disorder; or the effect of such additional disorders or diseases. The additional disorder may also be a behavioral or mental disorder.Portable oxygen concentratorPulmonary gas pressures: The factors that determine the values for alveolar pO2 and pCO2 are:Obesity hypoventilation syndromeRiding-like sittingTranspulmonary 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.Anesthesia cart: Anesthesia carts are hospital devices used to store tools that are necessary for aid during procedures that require administration of anesthesia. Anesthesia refers to the use of drugs to subdue a patient's mind and prevent him or her from feeling any pain during a surgical operation.Diaphragm pacing: == Introduction ==Closed-ended question: A closed-ended question is a question format that limits respondents with a list of answer choices from which they must choose to answer the question.Dillman D.Luis Gabriel Cano: Luis Gabriel Cano Isaza (1924-2010)El Espectador obituary (In Spanish) was the President and publisher of El Espectador who won the Golden Pen of Freedom Award in 1990 for his writings on the cocaine traffic. His brother Guillermo, who had also worked on the paper, had been assassinated by drug gangs.Home appliance: Home appliances are electrical/mechanical machines which accomplish some household functions, such as cooking or cleaning. Home appliances can be classified into:Dorsal respiratory group: The dorsal respiratory group (DRG) is located in the dorsomedial region of the medulla, and is composed of cells in the solitary tract nucleus. The DRG is one of two known respiratory neuron localizations, with the other being the ventral respiratory group.Surgical mask: A surgical mask, also known as a procedure mask, is intended to be worn by health professionals during surgery and during nursingProcedure mask. to catch the bacteria shed in liquid droplets and aerosols from the wearer's mouth and nose.Withdrawal reflex: The withdrawal reflex (nociceptive or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. It is polysynaptic, causing stimulation of sensory, association, and motor neurons.Effects of sleep deprivation on cognitive performance: It has been estimated that over 20% of adults suffer from some form of sleep deprivation. Insomnia and sleep deprivation are common symptoms of depression and can be an indication of other mental disorders.Positional asphyxia: Positional asphyxia, also known as postural asphyxia, is a form of asphyxia which occurs when someone's position prevents the person from breathing adequately. Positional asphyxia may be a factor in a significant number of people who die suddenly during restraint by police, prison (corrections) officers or health care staff.
