This study is a 3-legged randomized study examining whether during shoulder surgery performed in the beach chair position active compressions of the lower leg with a sequential compression device (SCD) have a superior effect on stabilizing cerebral and circulatory hemodynamics when compared to TED stockings or a control group without any stockings.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Sequential compression device | Experimental | During arthroscopic shoulder surgery, an SCD device will be applied to the patients legs during surgery. Cerebral oxygenation and circulatory parameters will be recorded continuously throughout the surgery. Recordings will be hidden to the primary caregiver. |
|
| TED stockings | Experimental | During arthroscopic shoulder surgery, TED stockings will be applied to the patients legs during surgery. Cerebral oxygenation and circulatory parameters will be recorded continuously throughout the surgery. Recordings will be hidden to the primary caregiver. |
|
| Control | No Intervention | no stockings will be applied to the patients legs |
| Name | Type | Description | Arm Group Labels | Other Names |
