Applying a tourniquet for up to 3 minutes helps dilate the vein and make it easier to locate for venipuncture. Elevating the extremity and applying a cool compress may help with discomfort and reduce swelling, but they do not directly dilate the vein. Applying an alcohol swab for 60 seconds is important for sterilization, but does not help dilate the vein.
