Medical Assistant Prep / Unit 20 MAS 477 short lesson, about 20 seconds
Applying the Tourniquet
Captions available
The idea
The tourniquet goes on about four to five finger widths above the planned puncture site.
In practice
It should be snug enough to make the veins more prominent, but loose enough that you can still feel an arterial pulse below it; then re-examine the vein.
Where people slip
A tourniquet that stops the arterial pulse is too tight.
