air (âr)

n.

1. A colorless, odorless, tasteless, gaseous mixture, approximately 78 percent nitrogen and approximately 21 percent oxygen with lesser amounts of argon, carbon dioxide, hydrogen, neon, helium, and other gases.

2. This mixture, with varying amounts of moisture and particulate matter, enveloping Earth; the atmosphere.

3. Any of various respiratory gases. No longer in technical use.

air

Etymology: Gk, aer

the colorless, odorless gaseous mixture constituting the earth's atmosphere. It consists of 78% nitrogen; 20% oxygen; almost 1% argon; small amounts of carbon dioxide, hydrogen, and ozone; traces of helium, krypton, neon, and xenon; and varying amounts of water vapor.

air capillaries

the minuscule vessels that connect the parabronchi in avian lungs, in which there are no blind-ended tubules.

air cell

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.

air dried

said of feed that is dried in the open with only natural movement of air, e.g. conventional hay. Contains about 10% water.

air filtration

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.

air hunger

a distressing dyspnea affecting both inspiration and expiration which occurs in paroxysms; characteristic of diabetic acidosis and coma. Called also Kussmaul's respiration.

air movement

includes air changes voiding humidity and gases to the exterior plus movements within the space which facilitate cooling.

air passages

the combined air delivery system of the upper and lower respiratory tracts including nasal cavities, pharynx, laryngeal cavity, trachea, bronchi and bronchioles.

air pollution

contamination of the air with deleterious or esthetically unattractive chemical, physical or biological material. Usually reserved for pollutants generated by humans.

air pump

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.

air quality

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.

air trapping

dilatation of alveoli without destruction of their walls.

air vesicles

extend radially from parabronchi in the lungs of birds and connect with air capillaries, in which gaseous exchange occurs with vascular capillaries.

Patient discussion about air capillaries.

Q. Does anyone know what could make you gasp for air after you have fallen to sleep? I also have a pounding heart and I am panting and sweaty. I have a mitral valve prolapse and sinus tachycardia(which I was told was that meant )palpitations

A. if you have what i have ,that is palps i get shortness of breathe,fast heart beats, all i do is take a deep cough, and it goes away,try it if all eles fails,if this is what you have there is a surgery for it, but only in serious cases,my mother just had it done....

Q. can an HIV virus last when it comes in contact with air and out of the body? in what ways can i get HIV? and what are the treatment options ? is it treatable ? and what are the side effects for this kind of treatment ?

A. This virus may be passed from one person to another when infected blood, semen, or vaginal secretions come in contact with an uninfected person’s broken skin or mucous membranes*. In addition, infected pregnant women can pass HIV to their baby during pregnancy or delivery, as well as through breast-feeding. People with HIV have what is called HIV infection. Some of these people will develop AIDS as a result of their HIV infection. http://www.cdc.gov/hiv/resources/qa/qa1.htm

Q. Are superbugs contagious through the air? Last week we visited my dad in the hospital, and we noticed that on the next room’s door there was a warning sign. After asking, we were told it was a denoting that the patient inside had a superbug (called klebsiella). On our way out we passed against this patient in the hallway – is it possible that I also carry this superbag? Is it dangerous?

A. Usually these bacteria are transmitted from person to person through direct contact, and less through the air. Moreover, these germs are dangerous in ill and debilitated patients, and not in normal healthy individuals.
