Why is medical oxygen a challenge for people travelling by air?

There are currently 3.5 million people in Europe who require medical oxygen, and as life expectancies increase, this figure is likely to grow. At the same time, air travel is becoming more accessible to a wider range of people, as costs of flights fall, and airlines and airports make improvements to the accessibility of their services. People who need medical oxygen to fly experience a wide range of difficulties when planning to travel by plane, and sometimes during or after the flight. A European Commission Regulation (EC No 1107/2006) sets the standard for airlines when it comes to making air travel accessible, but healthcare professionals and oxygen providers can both help patients to navigate the various requirements for using medical oxygen when travelling. In this review, we discuss the journey of the patient planning to travel by air, from initial consultation and fit-to-fly test, through to planning their air travel and oxygen supply, travelling, and arriving at their destination. We also highlight some common problems at each stage and suggest points for healthcare professionals to discuss with patients. KEY POINTS: Patients who require medical oxygen for air travel should begin planning their trip as far in advance as possible. It is very advantageous for healthcare professionals to be able to advise patients on travelling with oxygen and what they need to do. Requirements and policies can vary greatly between airlines, causing problems for patients who are trying to book their flights. Patients or their carers need to be confident operating their oxygen equipment, as the stress of travel and lack of medical assistance on an airplane can put them at risk. Careful arrangements need to be made by the patient to make sure that they have the correct oxygen therapy at their destination, and can access support if they need it. EDUCATIONAL AIMS: To understand the process and potential challenges for a patient who requires oxygen to travel by plane. To be confident in discussing air travel with patients who are affected by lung disease.
