When the body is properly hydrated, blood pumps through the veins more readily, making those veins larger and easier to see. It’s harder to locate a vein on a person who is dehydrated. If you suspect that the person is dehydrated, ask them to drink 2 to 3 glasses of water before you deliver the injection.  Juice, tea, or decaf coffee can also help to rehydrate the person. If the person is severely dehydrated, they may require intravenous fluids. Continue to look for a vein if they’re unable to drink fluids. The veins in this area of the arm are the safest to inject into and they are usually easier to find here as well. Ask the person if they have a preference about which arm you inject into. Then, look at the person’s arm to see if you can spot a vein. If not, you may need to bring it to the surface.  When delivering frequent injections, alternate arms every other day to prevent the veins from collapsing. Use extreme caution if you're injecting into the hands or feet. The veins here are often easier to find, but they are also more fragile and can collapse easily. Injecting into these areas can also be quite painful. If the person is diabetic, don't inject into their feet because it's too risky. Wrap an elastic tourniquet 2 to 4 in (5.1 to 10.2 cm) above the injection site. Use a loose overhand knot or simply tuck the tourniquet ends into the band to secure it. For injections delivered to the inner elbow, make sure that the tourniquet is tied above the mound of the bicep and not over the bicep itself.  The tourniquet must be easy to remove. Never use a belt or other stiff piece of fabric as this will distort the shape of the veins.  If the vein is difficult to see, consider tying the tourniquet over the shoulder to help squeeze blood into the arm. You can also give the person a stress ball and ask them to squeeze it and release it several times. Watch to see if the vein becomes more visible after about 30 to 60 seconds of this. Once you find a vein, place one finger over it. Use this finger to gently press up and down in a gentle bouncing motion for 20 to 30 seconds. This should cause the vein to expand and become slightly easier to see. Don’t press too hard! Use gentle pressure to palpate the vein. Warmth causes the vein to dilate and grow, making it easier to find. If you need to warm the injection site, microwave a damp towel for 15 to 30 seconds and place the warm towel over the vein. You could also soak the injection site directly in warm water.  Other options for warming up the entire body include drinking a warm beverage, like tea or coffee, or taking a warm bath. Never administer an injection to someone who is in a bathtub! Depending on the effects of the injection, this may put them at risk of drowning. Make sure that the skin at the injection site is clean before delivering the injection. Once you have a vein that is ready to use, wipe the injection site with an isopropyl alcohol pad. If you do not have prepared cleansing pads, soak a sterile cotton ball in isopropyl alcohol and use that to clean the area.
