Shock Flashcards
1
Q
What is shock
A
Abnormality of the circulatory system resulting in inadequate tissue perfusion and oxygenation
2
Q
What do all shocks lead to
A
Decreased CO/SV therefore inadequate oxygenation and perfusion
3
Q
Hypovolaemic shock
A
Loss of volume (blood, fluids) leads to decreased venous return
4
Q
Cardiogenic shock
A
Decreased myocardial contractility
5
Q
Obstructive shock example
A
Tension pneumothorax
6
Q
Obstructive shock
A
Increase in intra-thoracic pressure causes decreased venous return
7
Q
Neurogenic shock
A
Loss of vasomotor tone causes increased vasodilation and decreased venous return
8
Q
Vasoactive shock
A
Release of vasoactive mediators causes vasodilation and decreased venous return
