AIR


air

(ār),
1. A mixture of odorless gases found in the atmosphere in the following approximate percentages by volume after water vapor has been removed: oxygen, 20.95; nitrogen, 78.08; argon 0.93; carbon dioxide, 0.03; other gases, 0.01. Formerly used to mean any respiratory gas, regardless of its composition.
2. Synonym(s): ventilate

AIR

Aerosolised Iloprost Randomised Study. A trial comparing functional changes caused by iloprost, a stable prostacyclin analogue, to placebo in patients with pulmonary hypertension.
Primary endpoint 10% increase in 6-minute walking distance and an improvement in the NYHA functional class.
Conclusion Iloprost was better than placebo. Combined clinical endpoint was met by 17% vs. 5% in the placebo group, distance walked in 6 minutes was 36 meters greater, functional class improved, dyspnoea decreased, quality of life increased, and fewer treated patients died or deteriorated. Syncope was similar in both groups.
Adverse events Tolerable flushing and jaw pain.

AIR

Abbreviation for 5-aminoimidazole ribose 5-phosphate; 5-aminoimidazole ribotide.

air

The mixture of gases forming the atmosphere of the earth. It consists of about 78% nitrogen, 21% oxygen, 0.1% argon, 0.03% carbon dioxide and smaller proportions of rare gases and ozone. A continuing adequate supply of oxygen is essential to life.

Patient discussion about air

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.

Q. breating air that has tetrachloroethene in it how does it affect you if u have prostate cancer the air in my building has been determined to have Tetrachloroethylene in it i have just been diagnosed with prostate cancer

A. i found a research they did in Finland about tetrachloroethene, and they saw that amongst the people who were exposed to it over the years there was an increased amount of cancerous events. and even prostate cancer.

here is a link to the abstract-

Q. where would i find list of all the "clean" cities and the rates of air pollution ...?

A. i don't know about a list of "good" cities, but i know a list of the worse cities for Asthmatic people!-

The evaluated PCOC3 air cleaner was found to remove selected VOCs at rates in the range of a few air changes per hour in the test rig used.
"In an everyday use mode, it's white-noise type quiet yet it's still delivering six air changes per hour."
* The exhaust rate is based on 10 air changes per hour;
The machines must be capable of between 10-15 air changes per hour and have a proven track record of use in an accute hospital setting.
1 illustrates the pressure distribution in the elevator shaft and the floors when the floors are charged with outside air at a volume flow rate of two air changes per hour. For this situation the floor pressure increases and the NPP is pushed above the top of the building, thus improving air quality for occupants on the upper floors.
Another is the power or capacity of a unit expressed in air changes per hour (ACH), or in cubic feet per minute (CFM) of air flow.
The 3 air changes per hour value you refer to is not a "real" air change rate but the rate determined at a pressure difference of 50 Pa.
The resolution is one injection of tracer over a 15-minute interval, or 0.015 air changes per hour. Changing the averaging time to one hour would reduce this value by a factor of 4 to 0.004 air changes per hour.
Furthermore, the additional infiltration due to the combustion air is on the order of less than 0.1 air changes per hour, so it probably has little effect on indoor humidity levels anyway.
* Air change rates were maintained at eight air changes per hour in the office spaces and 15 changes per hour in the large meeting and conference rooms.
