简要总结

The aim of the study is to compare the accuracy of peripheral blood oxygen saturation measurements using smartwatches from three manufacturers compared to a standard medical pulse oximeter.

详细描述

The aim is to create a study that compares multiple smartwatch models simultaneously with a standard medical pulse oximeter using a single measurement methodology. According to the available literature, no such study exists. The methodology of the study and the subsequent statistical evaluation are based on the guidelines of the standard ČSN EN ISO 80601-2-61, which specifies requirements for the basic safety and necessary functionality of pulse oximetry devices. The comparison will be performed non-invasively in healthy volunteers during gradual desaturation in the range of 70-100 % SpO2 (normobaric hypoxia). The data obtained could help to increase the awareness of the possibilities of SpO2 monitoring using smartwatches in medical conditions that are manifested by a decrease in SpO2 level over a longer time period, where measurement with a conventional oximeter is impractical.

研究组 & 干预措施

First smartwatch model

Experimental

Volunteers sequentially inhale three hypoxic gas mixtures each for 2.5 minute. Every measurement will begin with a two-minute stabilization phase, during which the physiological values of the volunteer will be checked. During the experiment, SpO2 measurements will be taken by hand from the watch and the pulse oximeter simultaneously.

干预措施: Hypoxia and Smartwatch model (Other)

Second smartwatch model

Experimental

Volunteers sequentially inhale three hypoxic gas mixtures each for 2.5 minute. Every measurement will begin with a two-minute stabilization phase, during which the physiological values of the volunteer will be checked. During the experiment, SpO2 measurements will be taken by hand from the watch and the pulse oximeter simultaneously.

干预措施: Hypoxia and Smartwatch model (Other)

Third smartwatch model

Experimental

Volunteers sequentially inhale three hypoxic gas mixtures each for 2.5 minute. Every measurement will begin with a two-minute stabilization phase, during which the physiological values of the volunteer will be checked. During the experiment, SpO2 measurements will be taken by hand from the watch and the pulse oximeter simultaneously.
