Non-invasive Blood Pressure Measurement Using Samsung Smartwatch

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to verify the accuracy of blood pressure and heart rate measurement by Samsung smartwatches compared to a standard monitor of vital signs used in intensive care units.

Detailed Description
-----------------
Recently, wearables, like smartwatches, have been gaining new possibilities in monitoring biological signals and they are used for home monitoring of health conditions. Heart rate measurement is a common function of smartwatches, some smartwatch models even measure blood pressure. The study aims to compare the measurement of blood pressure and heart rate using the latest smartwatch with a vital signs monitor used in clinical practice. Blood pressure and heart rate measurements will be taken by hand from the watch and the vital signs monitor simultaneously. The agreement of the measurements of both devices will be evaluated.

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Blood pressure and heart rate measurement<br>Calm measurement of blood pressure and heart rate simultaneously by smartwatch and vital signs monitor. Each participant will undergo this measurement a total of 6 times. | Other: Calm measurement of blood pressure and heart rate (before physical activity)<br>* Simultaneous blood pressure and heart rate measurements at minutes 2 and 5.5 of the experiment.<br>Other: Physical activity<br>* Five minutes of physical activity, between times 7.5 min and 12.5 min of the experimental part. Riding on a spinning ergometer with a standardized load of 1 W/kg.<br>Other: Calm measurement of blood pressure and heart rate (after physical activity)<br>* Simultaneous blood pressure and heart rate measurements at times 15.5, 17, 20.5 and 22 minutes of the experimental part.<br>|
