Breathing, difficulty

OZONE A reactive form of oxygen the molecule of which contains 3 atoms of oxygen. In the ozone layer it protects the earth by filtering out ultra-violet rays. At ground level, as a constituent of photochemical smog, it is an imtant and can cause breathing difficulties.

Breathing difficulties, i.e. bronchitis or asthma, arising from sensitization to bacterial contamination or additive chemicals, have been reported. 

The Immediately Danger to Life or Health (IDLH) level for CO2, set by the National Institute for Occupational Safety and Health (NIOSH) is 50,000 ppm. At that level, vomiting, dizziness, disorientation, and breathing difficulties occur ifler a 30-minute exposure at a 100,000 ppm, death can occur after a few minutes, even if the oxygen in the atmosphere would otherwise support life. 

High concentrations of SO, can produce tempo-rai y breathing difficulties in asthmatic children and in adults who are active outdoors. Sulfur dioxide also can directly damage plants and has been shown to decrease crop yields. In addition, sulfur oxides can be converted to sulfuric acid and lead to acid rain. Acid rain can harm ecosystems by increasing the acidity of soils as well as surface waters such as rivers, lakes, and streams. Sulfur dioxide levels fell, on average, by 39 percent between 1989 and 1998. 

W ithin the past few years a number of new drugs have been introduced to treat respiratory disorders, such as bronchial asthma and disorders that produce chronic airway obstruction. This chapter discusses the bronchodilators, dragp that have been around for a long time but are still effective in specific instances, and the newer antiasthma drugs that have proven to be highly effective in the prophylaxis (prevention) of breathing difficulty. 

Remove to fresh air Get medical attention for any breathing difficulty. 

Isocyanates are quite toxic materials and need careful handling. They affect mainly the respiratory tract causing breathing difficulties, sore throats and, in extreme cases, bronchial spasms. Once they have been allowed to react, for example to form foams, they undergo complete conversion and appear to leave no toxic residues.

The combustion products from sulfur Impurities In coal are particularly damaging to the environment. In humans, prolonged exposure to sulfur dioxide diminishes lung capacity and aggravates respiratory problems such as asthma, bronchitis, and emphysema. Concentrations as low as 0.15 ppm can incapacitate persons with these diseases, and at about 5 ppm everyone experiences breathing difficulties. In 1952 a particularly serious episode of SO2 pollution In London caused approximately 4000 deaths over several days.

Symptoms of intoxication in humans caused by accidental ingestion of Kou-Wen plants have been described as follows. The effect on the digestive system starts with loss of appetite and turn of the stomach, and continues to severe abdominal pain and intestinal bleeding. The effect on the respiratory system presents as breathing difficulties which finally lead to death by respiratory failure. The effect on muscle innervation usually results in generalized muscular weakness and paralysis of the limbs. The effect on the circulatory system starts with heartbeat disorders and a drop in blood pressure, but heart failure is not a common cause of death. In addition to dilation of pupils, a drop in body temperature and proliferation of white blood cells have also been obseryed (70). 

Colorless, water-white, or pale-yellow, oily liquid with a mild, skunk-like odor detectable at 0.5 ppm. This material is hazardous through inhalation and ingestion, and produces local skin/eye impacts. It causes irritation to the eyes, skin, respiratory system cough dizziness, dyspnea (breathing difficulty), lassitude (weakness, exhaustion), confusion, cyanosis abdominal pain, nausea skin sensitization. 

This material is hazardous through inhalation and ingestion. Symptoms from ingestions include diarrhea (may be bloody), dysentery, and hemolytic-uremic syndrome (HUS). Symptoms from inhalation are not fully documented but may result in breathing difficulty due to fluid accumulation in the lungs. 

No longer is asthma considered a condition with isolated, acute episodes of bronchospasm. Rather, asthma is now understood to be a chronic inflammatory disorder of the airways—that is, inflammation makes the airways chronically sensitive. When these hyperrespon-sive airways are irritated, airflow is limited, and attacks of coughing, wheezing, chest tightness, and breathing difficulty occur. 

Symptoms of the acute phase are acute respiratory distress, breathing difficulty, profuse sweating, turning bluish in color, high temperature, and increased pulse and respiratory rate with chest sounds. If an x-ray is performed, mediastinal widening (swelling of lymph nodes under the breastbone) is very characteristic. Shock and death usually follow within 24 to 36 hours after the onset of respiratory distress. The fatality rate from inhalation anthrax ranges from 65 to 90% even with antibiotic therapy.3... 

Treatment — No specific antiviral therapy exists to treat Venezuelan equine encephalitis. Treatment is geared toward relieving headache or myalgia, controlling convulsions, and aiding breathing difficulties. Several experimental drugs (e.g., vaccines TC-83 and TC-84) have shown some promise in the treatment of this virus, but current data on their effectiveness in humans is insufficient.3...
