Arteries Vs. Veins: How to Tell the Difference and Stop the Bleeding

Arteries flow away from the heart (red). Veins flow back toward it (blue).

by James Hubbard, M.D., M.P.H.

When trying to stop a cut from bleeding, you need to know how to tell the difference between a bleeding vein and a bleeding artery.

Memorize this saying: Arteries spurt. Veins don’t.

Arteries carry oxygen-rich blood from the heart to tissue. Veins drain the blood back to the heart to resupply it with oxygen.

Arteries pump. Veins dump.

Step 1: Apply pressure.

  • Use gauze or a clean cloth. If you don’t have anything else, use a gloved hand. If it’s yourself, as a last resort, use your bare hand. If it’s others, beware you could be exposing yourself to a blood-borne disease. Stuff a gash with a cloth (the cleanest you have) or gauze, and hold pressure. A shirt will do.

Step 2: Determine whether it’s an artery or vein.

  • If the blood is oozing, it’s a vein. The blood is probably also a darker color because it doesn’t have as much oxygen. The bleeding usually stops after about five minutes of pressure. If you can’t apply direct pressure, apply pressure just distal (toward fingers or toes) to the wound. Remember, it’s draining back to the heart.
  • If the blood is spurting, it’s an artery. Arteries contract and expand to aid in pumping the flow. They may need more pressure to stop the bleeding. If pressure does stop it, hold the wound for up to fifteen minutes if you can. Then pack it with clean cloth and apply a bandage. The bleeding should be under control before closing the wound with suture or tape.
  • If you can’t apply enough pressure to stop the bleeding, try pressing down just proximal to the wound (the side of that’s closer to the heart). Remember, the blood is coming from the heart. Arteries are too deep to see them from your skin surface, but sometimes you can feel the pulsing. If you can’t, just press in different areas proximally until the bleeding stops. Then pack and bandage.
  • A tourniquet placed proximal to the arterial bleeding (toward the heart) will stop it, but could cut off enough blood supply that you could lose limb. If you must, use material about two inches wide and wrap just tight enough to stop the bleeding. (The same goes for wrapping any bandage.) If you can wedge two fingers under it you’re probably okay, but still loosen it every few minutes to let the blood flow distally.

Note: Small cuts and scrapes are usually capillaries. They connect the arteries to the veins and are very small. Bleeding from capillaries can usually be stopped fairly easily. Even if they’re squirting, a little pressure for five to 10 minutes does the trick.

Step 3: Get medical care.

    I was doing some chores around the house and then I had accidentally cut my foot open while moving a whiteboard. The cut is really deep and it hurts whenever I move it. Actually it hurts in general moving or not. And when I touch it there is something sticking up.

  • Sky

    I got into an accident on my wrist. it was bleeding for quite awhile but doesn’t seem too deep. I have a numb type of feeling in my pinky finger, is that weird?

      If it doesn’t go away in a few days you may have injured a nerve and need to have it checked out.

    My father is a diabetic he hits his middle finger and blood started squirting out about 2 feet across the room. At times he gets it to stop but if he slightly bangs it blood starts squirting out all over again. He’s told his doctor but they said they can’t do anything for him unless he goes in when he’s actually bleeding. At times he can be bleeding for 7 or 8 hours.

    • James Hubbard, MD, MPH

      Christina, you should be able to stop any bleeding of the finger with pressure. If you’re not sure, check out some of my posts on wounds. Of course if you take the pressure off, the bleeding may start back, especially if it’s an artery. In addition, he should see the doctor when he’s bleeding. As soon as it starts, call the doctor’s office and find out if he should go to the office, ER, or urgent care clinic. If the doctor is not available by phone or has someone on call for him, an urgent care would be a good choice.

      • Christina

        Yes the bleeding does stop with pressure but right when we stop applying pressure it starts up again. Today he is not bleeding but yesterday he was bleeding so long he started to get dizzy. Yesterday his doctors office was closed. Is the emergency or urgent care the best option when blood is squirting out of his finger and we can’t get it to stop? I read online you can you cornstarch or sugar to stop the bleeding but wasn’t sure if that was such a great idea.

    I accidentally cut myself inbetween my knuckles and it will not stop bleeding even with pressure. It’s even spurting blood everywhere.

  • Tiffany

    I sliced the tip of my thumb while cutting potatoes it has had constant pressure and is still bleeding 5.5 hours after the fact. My thumb tip is very white and swollen and thumb is pulsating along with my heart beat. Any advice? Took tramadol but it still aches.

    • James Hubbard, MD, MPH

      I can’t give you individual advise. In general, if you sliced a small, shallow piece off the tip, you may need to apply constant, direct pressure for 15 minutes or more and then continue the pressure with a pressure bandage.
      If you’ve taken an aspirin or other blood thinner within the last 24 hours, it may take longer. If it won’t stop then, it’s cut deeply, or cut anywhere but the tip, you should see a doctor.

    I gashed my pinky under the nail abd ib the side, the hispital cleaned it last night i changed bandage this morning and there us still so much blood. Is that normal and should i be changing the bandage every time it bleeds through?

    • James Hubbard, MD, MPH

      If it is still bleeding, you should check with the hospital or follow up with your regular doc/urgent care.

  • Kayla

    I cut my finger at the tip. The bleed continued for 6 hours and was pulsing from the bandage in tune to my heart beat. The Doctor thinks it was a capilliary served by the palmar artery rather than the artery itself. However it took 8 changes of dressing over a 4 hour period so I lost a lot of blood. It’s 48 hours since the episode now and I’m going to have the dressing removed and renewed by a clean one. The throbbing has been constant which, they say, is good as it indicates that the artery is becoming sealed and trying to bleed. The final treatment was clinical ‘superglue’ – so hopefully that has sealed the wound. If not, and it starts to bleed again I will have to have surgery to open the wound again and then to closit with stitching. A query was raised at the hospital as to whether or not to surgically repair it straight away but they gave me a chance for it to heal itself, fortunately!

      Thanks for sharing, Bobby.

  • Cathy

    Varicose veins also spurt.

    • James Hubbard, MD, MPH

      Good point, Cathy. With varicose veins, if you lie down, they don’t. They spurt for the same reason puncturing a bucket of water with a nail does. Arteries spurt because they’re walls are actually pumping. If you’re standing or lying down and they pulsate. But, bottom line is you’re right. Seems everything has exceptions when I try to simplify. Thanks.

        I actually wanted to ask aquestion..i must have hit my artery when i feel a small very poiny piece of wood went n my leg it got very swollen and red i went to er they gave my antibiotics keflex! Its been almost 2months i have a huge whole but its a big blood scab it dosnt hurt but wilk that go away soon??

        • James Hubbard, MD, MPH

          You should definitely follow up with a doctor asap. If you have a regular doctor, call her/him and describe your problem, or go to an urgent care. Most any wound should be healed or well on it’s way 2 months out.
