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.

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!-

More importantly, we observed somewhat higher correlation coefficients for [FEV.sub.3]/FVC with IC, [FEF.sub.25-75] and the air trapping measures - RV and RV/TLC - in [FEV.sub.3]/FVC < LLN subgroup than the correlations observed in [FEV.sub.1]/FVC <70% subgroup (Table 5).
Both groups, including [FEV.sub.1]/FVC <70% and [FEV.sub.3]/FVC < LLN subjects, had significantly increased hyperinflation and air trapping with regard to RV, RV/TLC, TLC compared to [FEV.sub.1]/FVC [greater than or equal to]70% and [FEV.sub.3]/FVC [greater than or equal to] LLN groups, respectively.
With the exception of architectural distortion and traction bronchiectasis, the follow-up thin-section CT findings included ground-glass opacity (15/2; 62.5%), parenchymal bands (10/24; 41.7%), air trapping (9/24; 37.5%), and reticulation (8/24; 33.3%).

In the present study, the most common finding on HRCT was air trapping (77%) followed by bullous emphysema (59%), paraseptal emphysema (41%) and non-bullous emphysema (35%).
The above variation is due to consideration of air trapping as a radiological feature of emphysema in the present study as described by KNUDSON et al (1991) and GEVENOIS et al (1996).
Air trapping did not show any strong association with the physiologic parameters of airway obstruction, either FEV1 or FEF 25-75.
The major abnormalities reported are bronchial wall thickening, bronchiectasis, thick linear opacities, mucoid impaction and air trapping. (6,12,14) Lynch et al.
Physiologic factors may explain why, even though most WTC workers developed asthma, this subset developed air trapping, he said.
