Summary

The aim of this study is to experimentally determine the effect of pulse oximeters from different manufacturers on measured perfusion index values in healthy subjects at rest and with and without motion artifacts.

Conditions

  • Perfusion Index

Interventions

OTHER

Resting conditions

The volunteer's hands are at rest and PI readings are taken for six minutes. After two minutes, there is always a randomized rotation of the sensors between the fingers.

OTHER

Movement artifacts

The volunteer periodically spreads his/her fingers and clenches them into a fist, and PI readings are taken for six minutes. After two minutes there is always a randomized rotation of sensors between the fingers.

OTHER

Circulation constriction

The volunteer's 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 sensors are randomly rotated, and the measurement is repeated.
