title: Changes of heart rate and blood pressure in registration of forced respiration flow-volume loop.
abstract: Changes in heart rate (HR) and finger mean blood pressure (MBP) during registration of the flow-volume loop of forced respiration in healthy young subjects were studied. Breathing patterns of performing the flow-volume loop of forced respiration (forced respiratory manoeuvre, FRM) as well as the related responses of cardiovascular parameters in different subjects were found to vary to a large extent. FRM has a remarkable influence on the cardiovascular system: during FRM the peak values of MBP were 19 +/- 9 mmHg higher than baseline values and the peak values of HR were 30 +/- 11 beats min-1 higher. We conclude that it is essential to pay attention to a remarkable elevation of blood pressure in functional breathing tests in patients with high blood pressure.
