Introduction
Need for new recommendations for managing passengers with respiratory disease planning air travel
Since the first British Thoracic Society (BTS) recommendations published in 20021 and web update in 2004,2 data from several studies have confirmed previous findings suggesting that neither resting sea level oxygen saturations nor forced expiratory volume in 1 s (FEV1) reliably predict hypoxaemia or complications of air travel in passengers with respiratory disease.3–7 It is thus now clear that there is no reliable threshold in these variables to determine accurately the safety of air travel or need for in-flight oxygen in an individual patient. Nevertheless, the need for practical recommendations remains. The new guidance covers bronchiectasis, cancer, hyperventilation and dysfunctional breathing, obesity, pulmonary arteriovenous malformations and sinus and middle ear disease, and has expanded sections on infection and comorbidity with cardiac disease.
UK airports handled over 235 million passengers in 20088 and around 2 billion passengers flew in 2006, 760 million worldwide.9 The average age of passengers is likely to rise, making comorbidity more likely. Over 30 years ago around 5% of commercial airline passengers were thought to have a pre-existing medical condition.10 With new ultra-long haul flights, passengers are exposed to cabin altitudes of up to 8000 ft for up to and sometimes more than 20 h. Longer journeys increase the odds of in-flight medical incidents, and physiological disturbances associated with moderate but prolonged hypoxia, prolonged immobility and protracted exposure to reduced barometric pressure are unknown. Longer flights may increase the risk of desaturation, perhaps reflecting a gradual fall in cabin oxygen pressure.11
There are no established methods for quantifying in-flight medical emergencies.12 A North American service offering radio link assistance for in-flight medical emergencies logs over 17 000 calls a year; respiratory events accounted for 10–12% of such calls from 2004 to 2008, the third most frequent diagnostic category (Dr Paulo Alves, MedAire Inc, …
