Summary

The aim of the study is to experimentally compare measured perfusion index values between smartwatch and a medical grade pulse oximeter in healthy subjects at rest and with and without motion artifacts and during exercise.

Conditions

  • Perfusion Index

Interventions

OTHER

Resting conditions

The volunteers hand is at rest and Perfusion index readings are taken for six minutes from pulse oximeter and smartwatch

OTHER

Movement artifacts

The volunteer periodically spreads his/her fingers and clenches them into a fist, and Perfusion index readings are taken for six minutes from pulse oximeter and smartwatch.

OTHER

Circulation constriction

The volunteers arm is constricted using a cuff to measure non-invasive blood pressure. The perfusion index value is monitored during the time of cuff pressure and cuff release. The measurement is followed by a 4-minute pause to allow the vascular supply to stabilize. The measurement is repeated three times.

OTHER

Physical exercise

The volunteer is seated on the exercise bike, rests his forearms on the handlebars and is instructed not to move his arms. The volunteer\'s heart rate is controlled to increase to 120 beats per minute. For five minutes, the perfusion index is recorded from a pulse oximeter and smartwatch.
