Shock Flashcards
1
Q
Shock
A
Inadequate tissue perfusion
Inadequate oxygenation to the tissues
2
Q
Hypovolaemic shock pathway
A
Loss of blood volume Decreased venous return Decreased EDV Decreased SV Decreased CO Decreased MABP Inadequate tissue perfusion
3
Q
Hypovolaemic shock causes
A
Haemorrhagic: trauma, surgery
Non-haemorhagic: vomiting, diarrhoea, sweating
4
Q
Haemorrhagic shock
A
Tachycardia (increased HR)
weak, fast, thready pulse (decreased SV)
Cold peripheries
Hypotension
5
Q
Cardiogenic shock
A
Damage to the heart causes sustained hypotension Decreased cardiac contractility Decreased SV Decreased CO Decreased MABP Inadequate tissue perfusion
6
Q
Cardiogenic shock causes
A
MI
7
Q
Obstructive shock
A
Increased intrathoracic pressure Decreased venous return Decreased EDV Decreased SV Decreased CO Decreased MABP Inadequate tissue perfusion
8
Q
Obstructive shock causes
A
PE
Pneumothorax (tension)
Cardiac tamponade
9
Q
Neurogenic shock
A
Loss of sympathetic tone
Decreased CO
Decreased MABP
Inadequate tissue perfusion
10
Q
Neurogenic shock causes
A
Spinal cord injury
11
Q
Vasoactive shock
A
Release of vasoactive mediators Venous and arteriolar vasodilation Decreased venous return Decreased TPR Decreased CO Decreased MABP Inadequate tissue perfusion
12
Q
Vasoactive shock causes
A
Septic shock
