Overview
Brief Summary
A tourniquet is used to stop abundant bleeding when simple compression is not effective. The investigators will study the vascular suffering of the tourniquets according to their location on the limb: limb (arm / thigh) or distal (forearm / leg). Vascular suffering will be evaluated by the loss of the radial doppler flux for the tourniquets placed on the upper limb and in the tibial anterior to the lower limb by the loss of the pulse oximetry pulse and the collection of the signs described by the volunteers (pain, Paresthesia, cold sensation).

Outcomes
Primary Outcomes
Lower limb : Pressure (mmHg) needed to abolish the pulse
Time Frame: 10 min
The main evaluation criterion for the inferior member is the pressure under the tourniquet, necessary to obtain an abolition of the anterior tibial pulse (measured in Doppler). By means of a balloon connected to a pressure gauge and fixed under each tourniquet, a measure of the pressure exerted (in mmHg) by the tourniquet (s) on the skin will be measured at laying. The comparison will be made for each type of pose (single vs stage) between the proximal and distal layers.
Upper limb : Assessment of Pain by Digital Evaluation (EN) after 10 min of compression
Time Frame: 10 min
The main evaluation criterion for the superior member is the assessment of the pain felt according to the location of the tourniquets at the time of laying and at 10min. For the same location of tourniquet, the pain caused by the laying of one versus two tourniquets will be compared. For proximal versus distal, comparisons will be made for 1 tourniquet and for staggered tourniquets.
Secondary Outcomes
- Pulse oximetry(10 min)
- Lower limb pain(10 min)
- Upper limb pressure under tourniquet(10 min)
- Loss of arterial Doppler pulse(10 min)
