Emphysema, a type of Chronic Obstructive Pulmonary Disease (COPD), occurs when the walls of the alveoli (air sacs) in the lungs are damaged, becoming less elastic and, therefore, less able to exchange carbon dioxide for oxygen. Smoking Cessation: If the emphysema has been caused by smoking, the person must quit to prevent further damage. 2  Bronchodilator Drugs: These drugs, which are taken either orally or with an inhaler, help to relax and open air passages or reduce inflammation and swelling.
A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For a given pressure, different liquids boil at different temperatures. For example, water boils at 100 Â°C (212 Â°F) at sea level, but at 93.4 Â°C (200.1 Â°F) at 2,000 metres (6,600 ft) altitude.
Conventionally, the water temperature at which water boils is considered to be 100 degrees Celsius or 212 degress Fahrenheit. However, these numbers are only valid at sea level. As barometric pressure changes so too does the boiling point of water. For instance, as elevation increases the boiling point lowers. On the top of Mount Everest, for example, boiling water is possible at a water temperature of 68 degrees Celsius or 154 degrees Fahrenheit. Conversely, in deep ocean vents, water can be much hotter than that without boiling.
