Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to obtain microvascular data from a healthy, heterogeneous population for assessing reference values for the parameters Functional Capillary Density (FCD), heterogeneity of FCD, Microvascular Oxygen Saturation (SmvO2) and Heterogeneity of SmvO2 for healthy adults with respect to gender, age, and skin type (Fitzpatrick scale)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary objective:

• Obtain reference data of the studied microvascular parameters in a healthy, heterogeneous population

Secondary objectives:

* Determine the reproducibility of the parameters obtained using the device produced by ODI Medical
* Confirm the safety of the device produced by ODI Medical

Study Groups

Examination with the ODI-Tech medical device

Diffuse reflectance spectroscopy (DRS) operating within the visible wavelength region will be used for the microvascular oxygen saturation and haematocrit measurements.

Computer-assisted microscopy (CAM) will be used for recording frames of skin microcirculation.

Group Type OTHER

ODI-Tech medical device

Intervention Type DEVICE

The device captures and stores frames of the movement of blood in capillaries and spectra containing information on oxygen saturation. Proprietary software is used to analyse the obtained frames and spectra to calculate microvascular parameters such as functional capillary density and microvascular oxygen saturation.

ODI-Tech can be brought to the patient's bedside and operates non-invasively. The device parts are in contact with the patient for less than 5 minutes.
