Bicycle Ergometry and Peripheral Hemodynamics: a Pilot Study

This study examines how cycling on an exercise bicycle affects blood flow and heart and circulation in 12 healthy adult men. The main measurement is the perfusion index, which indicates how well blood is flowing through the small blood vessels. The study also measures pulse waves, blood pressure, the time it takes for the pulse wave to travel through the body, changes in heart rate, and the relationship between pulse and breathing. In addition, two pulse oximeter systems, Masimo and Nellcor, are compared, as well as measurements taken from the forehead and the finger.
