Bleeding
may be external or internal. First aid is appropriate
for external bleeding. Bleeding may be from an artery,
a vein, or from a capillary.
ARTERIAL bleeding is characterized by spurts with
each beat of the heart. Blood is bright red in colour
although blood darkens when it meets the air. It is often
severe and hard to control.
VENUS bleeding is characterized by a steady flow
and the blood is dark, almost maroon in colour. Venus
bleeding is easier to control than Arterial bleeding.
CAPILLARY bleeding is usually slow, oozing in nature.
There is a higher risk of infection with capillary bleeding.
Minor
bleeding can be stopped with direct pressure over the
wound, as the blood will naturally clot. In order to prevent
infection, a sterile or clean bandage should be used.
If bleeding is severe, or if shock or internal bleeding
is suspected,
CALL IMMEDIATELY FOR EMERGENCY MEDICAL ASSISTANCE!
FIRST
AID
To
control bleeding:
Apply
DIRECT PRESSURE on the wound. Use a gauze dressing
if available. If a dressing is not available, use a rag,
towel, piece of clothing or your hand alone.
If bleeding continues, and you do not suspect a fracture,
ELEVATE the wound above the level of the heart
and continue to apply direct pressure.
If the bleeding still cannot be controlled, apply PRESSURE
AT A PRESSURE POINT. For wounds of the arms or hands,
pressure points are located on the inside of the wrist
(radial artery-where a pulse is checked) or on the inside
of the upper arm (brachial artery). For wounds of the
legs, the pressure point is at the crease in the groin
(femoral artery). Steps 1 and 2 should be continued with
use of the pressure points.
The final step to control bleeding is to apply a PRESSURE
BANDAGE over the wound. After the bandage is in place,
CHECK PULSE to make ensure sure circulation is
not interrupted.
When faced with the need to control major bleeding, it
is not important that the dressings you will use are sterile!
Use whatever you have at hand and work quickly.
Signs
and symptoms of INTERNAL BLEEDING:
.
bruised, swollen, tender or rigid abdomen
. bruises on chest or signs of fractured ribs
. blood in vomit
. wounds that penetrated the chest or abdomen
. bleeding from the rectum or vagina
. abnormal pulse and difficulty breathing
. cool, moist skin
CALL
IMMEDIATELY FOR EMERGENCY MEDICAL ASSISTANCE!
First aid in the field for internal bleeding is limited.
If the injury appears to be a simple bruise, apply cold
packs to slow bleeding, relieve pain and reduce swelling.
If you suspect more severe internal bleeding, carefully
monitor the patient. Be prepared to administer CPR
if required. Reassure the victim, control external bleeding,
care for shock, loosen tight-fitting clothing and place
victim on side so fluids can drain from the mouth.
