The main objective of this study is the demonstration of an increase of over 50% of the surface visible on ultrasound (mm2) of the axillary vein and subclavian vein in arm abduction (90 °) and external rotation (90 °) with respect to the surface of the subclavian vein along the arm body.
The secondary objective of this study is to investigate the anatomical relationships of these veins with the subclavian artery, the brachial plexus and the pleura, and assess the depth of the vein to the skin. Specifically, the following will be assessed:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 50 healthy volunteers | Experimental | The study population consists of healthy volunteers aged 18 to 50 years and without previous surgery, trauma, or thrombosis of the axilla or the shoulder girdle. |

| Ultrasound measures | Procedure | Ultrasound will be used to measure the surfaces of the axillary and subclavian veins with the arms in different positions. Our goal is to compare the vein surface area available among different vein-position combinations. Our goal does not include testing specific devices. |
| Measure | Description | Time Frame |
|---|---|---|
| vein surface (mm^2), subclavian vein with arm along side the body | baseline (transversal); Day 0 | |
| vein surface (mm^2), subclavian vein with arm in abduction and external rotation | baseline (transversal); Day 0 | |
| vein surface (mm^2), axillary vein with arm along side the body | baseline (transversal); Day 0 |
