Hyperoxia test: A hyperoxia test is a test that is performed—usually on an infant—to determine whether the patient's cyanosis is due to lung disease or a problem with blood circulation.:141Arteriovenous 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.Alveolar gas equation: The partial pressure of oxygen (pO2) in the pulmonary alveoli is required to calculate both the alveolar-arterial gradient of oxygen and the amount of right-to-left cardiac shunt, which are both clinically useful quantities. However it is not practical to take a sample of gas from the alveoli in order to directly measure the partial pressure of oxygen.Richard A Neubauer: Richard Allen Neubauer (16 January 1924–11 June 2007), was a physician known for his work in the use of hyperbaric oxygen therapy.Lung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.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.Carotid body: The carotid body (carotid glomus or glomus caroticum) is a small cluster of chemoreceptors and supporting cells located near the fork (bifurcation) of the carotid artery (which runs along both sides of the throat).Pulmonary gas pressures: The factors that determine the values for alveolar pO2 and pCO2 are:Central chemoreceptors: Central chemoreceptors of the central nervous system, located on the ventrolateral medullary surface in the vicinity of the exit of the 9th and 10th cranial nerves, are sensitive to the pH of their environment.Potassium selective electrode: Potassium selective electrodes are a type of ion selective electrode used in biochemical and biophysical research, where measurements of potassium concentration in an aqueous solution are required, usually on a real time basis.FulminateList of countries by carbon dioxide emissionsRespirometer: A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. They allow investigation into how factors such as age, chemicals or the effect of light affect the rate of respiration.Gas analysis: Gas analysis could refer to any of the following:Portable oxygen concentratorPermissive hypercapnia: Permissive hypercapnia is hypercapnia, (i.e.DimefoxCheyne–Stokes respirationAir 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.BRICHOS family: The BRICHOS family consists of a variety of proteins linked to major diseases, each containing a 100 amino acid BRICHOS domain that is thought to have a chaperone function.
