Lung Disease and Travel
Travelers with lung cysts, severe Chronic Obstructive Pulmonary Disease (COPD) , a large collection of fluid around the lungs ( Other travelers with lung disease may need supplemental oxygen while they are aboard an airplane. A doctor determines a person’s need for in-flight oxygen by measuring the level of oxygen in the blood. A low level of oxygen in the blood is called hypoxemia. Most airlines will provide in-flight oxygen if they are given a doctor’s prescription and advance notice. Travelers are not allowed to carry oxygen in any form aboard an airplane. Travelers who need oxygen during airport layovers must make their own arrangements, although most oxygen vendors will assist their regular customers without charge if they have services in the destination city. Other respiratory equipment, such as continuous positive airway pressure devices, can be accommodated on an airplane provided the equipment does not exceed the size allowed for carry-on luggage. However, travelers who need this equipment should allow extra time for security checks. Ground travel at high altitudes may present special problems because less oxygen is available than at sea level ( see Altitude Illness ). In general, people with mild or moderate lung problems do not have any difficulty at altitudes below 5,000 feet (1500 meters), but the higher the altitude, the greater the chance of problems. People with lung disease traveling in or through such areas should take the same precautions they would take if they were flying. Bus, train, car, and ship travel is safe for people with lung disease but requires planning to ensure a supply of oxygen. Commercial services can coordinate oxygen deliveries for travelers anywhere in the world. People with Asthma ,
