It's wise to call the airline again before your trip to reconfirm any assistance that you have requested. For COPD patients, whose main problem is moving air in and out of their lungs, getting sufficient oxygen is vital. Therefore, it is important that nothing be undertaken which inhibits this function. When traveling by car, train, or bus, COPD patients and others needing supplementary oxygen should have a supply available in case they pass through areas of excess air pollution. They should also avoid travel in a confined area, such as a bus where smoking is permitted, and ensure that they keep out of extreme temperatures, both hot and cold.
Oxygen deprivation is the biggest problem for people with pulmonary and heart conditions.
If persons with these conditions intend to travel to places at high altitudes where both oxygen and air pressure are greatly reduced, it is very important that they check with their doctor, who will probably administer breathing tests to monitor their lung power. They should strictly follow the advice given. Air travel is a special form of altitude problem since almost all aircraft fly above 21,000 feet. However, air travel offers many advantages for heart and lung patients since it is quick and involves little activity. If you are able to walk a full block reasonably fast you should be able to fly.
