Blood and shock 19 Flashcards
1
Q
What is the bodies natural response to bleeding?
A
Blood vessles will constrict (serious injuries can prevent this) and clotting will start
2
Q
What is the amount of blood loss that is considered serious for a adult, child, and infant
A
- Adults 1L
- child 1/2L
- infant 100-200ml
3
Q
Describe the first class of hemorrhage
A
- 15% blood loss
- body constricts vessels
- Pt remainds alert
- BP remains in normal limits
- Pulse remains in normal limits/ slightly increased but still strong
- RR,Skin color and temp remain normal
4
Q
Describe class 2 hemorrhage and its effects on the Pt
A
- 30% blood loss
- vasoconstriciton maintains BP with some difficulty
- blood flow shuts down to vital organs
- Decreased flow to kidneys, intestines, and skin
- Pt may become confused and restless
- skin turns pale, cool+ dry due to shutting down vital organs
- DBP may increase or decrease, likely to increase to due vasoconstriction
- Pulse pressure, the difference in SBP and DBP decreases
- rapid HR due to Sympathetic response
- Increased RR die to sympathetic response
- delayed capillary refill
5
Q
What is class 3 hemorrhage and its effects on PT
A
- 40% loss
- vasoconstriction cant maintain BP
- cardiac output/tissue ferfusion continues to decrease
- Pt becomes more confused, restless, and anxious
- classic signs of shock appear
- increase(rapid) HR and RR
- decreased BP
- cool clammy extremities

6
Q
What is class 4 hemmorhage and the effects on the PT
A
- more than 40% loss
- vaso now is an issues- furthers imparing tissue perfusion and celluar oxygenation
- Pt is lethargic droswy and styorous
- signs of shock are more pronouced
- Bp continues to fall
- Lack of Blood flow to brain and other vital organs
- Organ failure and death
7
Q
What are the 3 types of external bleed and describe them
A
- Arterial bleeding:bright red blood, spurting from wound, severed/damaged artery arteries are hard to stop due to the increase pressure
- Venous bleeding:dark red blood, flows steadly, severed/damged vein
- Capillary bleeding:dark red blood, oozes slowly from wound, usually clots spontainously, increased threat of infection
