OSA sufferers at risk when flying

SYDNEY, Australia--Travelers with sleep apnea have a higher risk of cardiac problems on commercial flights, say Australian researchers. The researchers studied 22 people with severe OSA during a simulated flight. People with OSA had lower levels of oxygen in their blood before and during the simulated flight. They also found that those with OSA increased their breathing intensity at about the same rate as healthy people. While that’s normal, OSA sufferers had higher heart rates and more demand for oxygen compared with healthy people, the researchers found. The findings of the study were presented at the American Thoracic Society’s 2008 conference in May.
