Study Notes
Types of Bleeding
- Arterial bleeding: Bright red blood spurting or flowing from a wound, indicating a damaged artery.
- Venous bleeding: Dark red blood flowing steadily from a wound, indicating a damaged vein.
- Capillary bleeding: Dark red blood oozing slowly from a wound, indicating damaged capillaries.
Tools to Stop Bleeding
- Tourniquet: Restricts blood flow to an extremity. Applies circumferential force to compress the bleeding vessel against bone.
- Dressings: Sterile pads applied directly to a wound to promote healing and protect it. Avoid touching the side contacting the wound.
- Hemostatic gauze/dressing: Contains a blood clotting agent. Encourages clotting at the injury site.
- Bandages: Coverings holding dressings in place; do not touch the wound. Typically made of gauze or absorbent material.
Signs of Major, Life-Threatening External Bleeding
- Blood spurting from the wound (arterial).
- Large volumes of blood pooling or not stopping.
- Blood-soaked clothing.
- Partial or complete limb amputation.
- Altered level of consciousness in a bleeding patient.
Using a Tourniquet to Stop Extremity Bleeding
- Recruit someone to apply pressure while preparing the tourniquet.
- Position the tourniquet as high as possible on the extremity, "high and tight," at a right angle.
- Do not apply over a solid object in clothing or on a joint.
- Pull the band tightly and fasten it.
- Twist the windlass until bleeding stops, then secure it.
- Check the injury site for bleeding and assess circulation below the tourniquet. Bleeding should stop, and there should be no pulse below the injury.
- Record the application time. Mark a "T" on the patient's forehead.
- Dress and bandage the wound if time and equipment allow; do not remove or loosen the tourniquet unless medical personnel are present. A second tourniquet can be applied adjacent to the first if needed.
Stopping Bleeding from Junctional Injuries (Neck, Armpit, Groin)
- Traditional tourniquets are ineffective.
- Have someone apply pressure while preparing first aid.
- Pack the wound with hemostatic gauze (or standard gauze if unavailable).
- Pressure helps stop bleeding, supports the injured area, and prevents further contamination.
### Additional Notes
- In cases of amputation, even without severe initial bleeding, apply a tourniquet. Bleeding may resume later.
- Severe bleeding can prevent adequate oxygen exchange to body tissues, even if breathing is normal. Stopping life-threatening bleeding is crucial.
Closed Soft-Tissue Injuries
- Closed soft-tissue injuries involve internal bleeding or blood pooling under the skin.
- Bruising: Discolored, flat, tender area with discoloration (black and blue) due to small blood vessel leakage.
- Swelling: Raised, firm, painful lump from larger blood vessel leakage.
- Treatment involves applying a cold pack; significant injuries should be treated as internal bleeding.
Open Soft-Tissue Injuries
- Open injuries expose skin, causing external bleeding.
- Types include amputations, eviscerations, puncture wounds, lacerations, and abrasions.
- First aid prioritizes bleeding control and preventing contamination.
Bleeding Types
- Arterial bleeding: Bright red, spurting blood from damaged arteries.
- Venous bleeding: Dark red, steady flow from damaged veins.
- Capillary bleeding: Dark red, slow oozing from damaged capillaries.
Tools to Stop Bleeding
- Tourniquets: Restrict blood flow to extremities; apply high and tight, above the injury site, not over joints.
- Dressings: Sterile pads applied directly to the wound.
- Hemostatic gauze: Contains clotting agents to encourage clotting.
- Bandages: Hold dressings in place, provide pressure, and prevent contamination.
Major, Life-Threatening Bleeding
- Signs include spurting blood, large blood volume, blood-soaked clothing, amputation, altered consciousness.
- Extremity bleeding: Use a tourniquet (preferred) or direct pressure/wound packing.
- Junctional bleeding (neck, armpit, groin): Pack wound with hemostatic gauze (or standard gauze if unavailable) and apply pressure.
Tourniquet Application
- Position high on the extremity, avoiding joints and solid objects under clothing.
- Tighten until bleeding stops, secure windlass, record time.
- Mark a “T” on the patient’s forehead.
- Do not remove or loosen unless medical personnel directs.
- May require a second tourniquet adjacent to the first.
Junctional Bleeding Treatment
- Pack wound with hemostatic gauze (or standard gauze if unavailable).
- Apply pressure; if bleeding persists, add more gauze without removing the saturated dressings.
- Secure with a pressure bandage once bleeding stops.
Minor Bleeding Treatment
- Cover wound with a clean dressing.
- Apply direct pressure until bleeding stops, adding layers if necessary without removing previous ones.
- Secure with a bandage once bleeding stops.
