air hunger(redirected from Breathing urge)
Also found in: Dictionary, Encyclopedia, Wikipedia.
a craving, as for food.
air hunger Kussmaul's respiration.
a form of respiratory distress characterized by gasping, labored breathing, or dyspnea.
air hun·ger(ār hŭng'ĕr)
1. A sensation resulting from lack of food, characterized by a dull or acute pain referred to the epigastrium or lower part of chest. It is usually accompanied by weakness and an overwhelming desire to eat. Hunger pains coincide with powerful contractions of the stomach. Hunger is distinguished from appetite in that hunger is the physical drive to eat, while appetite is the psychological drive to eat. Hunger is affected by the physiological interaction of hormones and hormone-like factors, while appetite is affected by habits, culture, taste, and many other factors. See: illustration
2. To have a strong desire.
air hungerDyspnea; breathlessness.
air hungerDeep and rapid gasping respiration of the kind that occurs in severe DIABETIC ACIDOSIS and coma.
air hun·ger(ār hŭng'ĕr)
the gaseous mixture that makes up the atmosphere. See also air sacs.
the minuscule vessels that connect the parabronchi in avian lungs, in which there are no blind-ended tubules.
the air-filled space between the internal and external shell membranes of a bird's egg.
air changes per hour
the standard measurements used to indicate the level of ventilation in a building especially with respect to removal of humidity, noxious gases and carbon dioxide.
said of feed that is dried in the open with only natural movement of air, e.g. conventional hay. Contains about 10% water.
used as a means of reducing contamination inside a building, the efficiency depending on the pore size of the filter. A technique of some value when combined with temperature control in reducing the prevalence of pneumonia in calves in intensive veal producing units.
air flow rates
are important in assessing the suitability of a ventilating system in animal accommodation. Standards for suitable flow rates for different species and age groups for heating and cooling are available.
air gap technique
in radiography, a technique to reduce scatter of radiation by increasing the distance between the patient and the surface of the cassette.
a distressing dyspnea affecting both inspiration and expiration which occurs in paroxysms; characteristic of diabetic acidosis and coma. Called also Kussmaul's respiration.
includes air changes voiding humidity and gases to the exterior plus movements within the space which facilitate cooling.
the combined air delivery system of the upper and lower respiratory tracts including nasal cavities, pharynx, laryngeal cavity, trachea, bronchi and bronchioles.
contamination of the air with deleterious or esthetically unattractive chemical, physical or biological material. Usually reserved for pollutants generated by humans.
a small electrically driven appliance used to provide a constant stream of air bubbles to aquaria. The bubbles themselves add little oxygen to the water but the constant disturbance of the surface of the water does.
the determination of air flow rate, temperature, humidity, freedom from bacteria, solid particles, obnoxious effluvia and poisonous gases—especially hydrogen sulfide and methane from sullage pits under the animal accommodation.
dilatation of alveoli without destruction of their walls.
extend radially from parabronchi in the lungs of birds and connect with air capillaries, in which gaseous exchange occurs with vascular capillaries.
