Wearable Health Technology for Perioperative Risk Assessment

The patient is asked to repetitively walk along a 15 m track, at their best speed, in six minutes. Before and after the exercise, blood arterial pressure and dyspnea level (via Borg scale) are assessed. Cardiac frequency and peripheral Oxygen saturation are assessed before the test, and every minute and in the two minutes following the exercise.
