Title Blood pressure and sympathetic activity in normotensive aviators during short-haul fixed-wings flights
Bibliographic information May 2000, Vol.71, No.5, p.531-535. Illus. 24 ref.
Abstract To evaluate the impact of in-flight stress on blood pressure (BP) and sympathetic activity during a short fixed-wing flight, 18 healthy and normotensive commercial captain aviators were studied during a 120-min flight period, divided into segments of pre-flight, take off, mid-cruise, approach and landing, and a 120-min control period. All subjects underwent BP monitoring, heart rate recording and urine collection for catecholamines. Systolic and diastolic BP (SBP/DBP) were higher during the flight, as a whole, when compared with the control period. During the flight period, SBP increased in the pre-flight, take-off, approach and landing segments, whereas DBP increased in the take-off, mid-cruise, approach and landing segments. Heart rate did not change in any flight segment. Urinary catecholamines increased during the flight period in comparison to control period. It is concluded that inflight stress increases BP of the normotensive aviators by sympathetic activation during short-haul flights.
