usually accomplished by putting a sterile gauge pads over the injury site and applying fingertip pressure directly to the point of bleeding.
direct pressure
2
- should be used in conjunction with direct pressure. If extremity is painful, swollen or deformed, do not elevate.
elevation
3
- applying a pressure to the arteries directly under the skin structure.
Pressure points
4
- since bleeding can be life threatening in an open wound to an extremity with possible bone or joint injury, if left unsplinted, movement can cause further damage to surrounding tissues and blood vessels.
splints
5
- bright red, spurting blood from a wound usually indicates a severed ar-tery. Blood shows rich in oxygen. Can be more difficult to control than any other type because of the higher pressure in the artery.
Arterial bleeding
6
dark red blood that flows steadily from a wound usually indicates a set. ered vein. Blood shows oxygen depletion
venous
7
dark red, slowly oozing blood usually indicates damaged capillaries. Often clots spontaneously.
capillary
8
- results in the decrease of blood volume available for perfusion of the body organs
Hypovolemic shock
9
- usually the result of spi nal or head injury, which causes the nervous system to loss control over the vasogenic system
vasogenic
10
a result of the body's abnormal reaction to foreign protein from a source
anaphylactic

- the first stage of shock wherein the body is able to use its normal defense mechanisms to maintain * perfusion and function
Compensatory shock
18
loss ability to compensate; systolic bp drops
decompensate
19
multi system organ failure-death
irreversible
20
causes of shock
fluid loss, pump failure, vasodilation
21
tx of shock
reassure pt, maintain patent airway, admin o2 check spo2, assist ventilation et co2, position, assist perfusion, keep pt warm, perform focused hx and physical, adjust 02 gain iv access, ecg
22
why does keeping a pt warm help in blood loss
the muscles shivers and it uses oxygen that is mostly needed by the brain
23
what to always do in case study
query mi query, physical exam, reassure!!!
