|
|
What are the general steps in controlling external bleeding? |
-Cover the wound with a dressing and press firmly against the wound with a gloved hand -Apply a pressure bandage over the dressing to maintain pressure on the wound and to hold the dressing in place. -If blood soaks through the bandage, do not remove the blood-soaked bandages, instead add more pads and bandages to help absorb the blood and continue to apply pressure. |
|
|

-Tender, swollen or bruised or hard areas of the body such as the abdomen -Rapid breathing -Skin that feels cool or moist or looks pale or bluish -Vomiting blood or coughing up blood -Excessive thirst -An injured extremity that is blue or extremely pale -Altered mental state, such as the person becoming confused, faint, drowsy or unconscious |

|
Arteries |
Large blood vessels that carry oxygen rich blood from the heart to all parts of the body, except for the pulmonary arteries, which carry oxygen poor blood from the heart to the lungs. |
|
|
Blood volume |
The total amount of blood circulating within the body. |
|
|
Capillaries |
Tiny blood vessels linking arteries and veins; they transfer oxygen and other nutrients from the blood to all body cells and remove waste products. |
|
|
Clotting |
The process by which blood thickens at a wound site to seal an opening in a blood vessel and stop bleeding. |
|
|
Direct pressure |
Pressure applied on a wound to control bleeding |
|
|
External bleeding |
Bleeding on the outside of the body; often, visible bleeding. |
|
|
Internal bleeding |
Bleeding inside the body |
|
|
Pressure bandage |
A bandage applied snugly to create pressure on a wound to aid in controlling bleeding. |
|
|
Tourniquet |
A tight, wide band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound. |
|
|
Veins |
Blood vessels that carry oxygen-poor blood from all the parts of the body to the heart, except for pulmonary veins, which carry oxygen-rich blood to the heart from the lungs. |
|
|
shock
|
A life-threatening condition that occurs when the circulatory system fails to provide adequate oxygenated blood to all parts of the body.
|
|
|
What are the three conditions necessary to maintain adequate blood flow?
|
-The heart must be working well -The blood vessels must be intact and able to adjust blood flow. -An adequate amount of blood must be circulating in the body |
|
|
Cardiogenic shock
|
Results from the failure of the heart to pump enough oxygenated blood.
|
|
|
Distributive shock
|
Results from abnormal dilation of the blood vessels. This condition leads to less oxygen being delivered to the body. Examples include neurogenic/vasogenic shock, septic shock or anaphylactic shock.
|
|
|
Hypovolemic shock
|
Results from severe bleeding or loss of fluid from the body. Insuffient blood volume can lead to this kind of shock.
|
|
|
What are the signals of shock?
|
-Apprehension, anxiety, restlessness or irritability -Altered level of consciousness -Nausea or vomitting -Pale, ashen or grayish, cool, moist skin -Rapid breathing -Excessive thirst |
|
|
What are the two conditions that frequently result in shock in children?
|
-Vomitting-Diarrhea
