Dehydration, hemorrhage
28
* Neurogenic shock is caused by?
Spinal injury (above T7)
29
* Anaphylaxis is caused by?
Allergy
30
What is oncotic pressure?
Molecules that keep blood inside capillaries
31
An increase in hydrostatic pressure causes an increase in?
BP
32

Allergy
35
What is oncotic pressure?
Molecules that keep blood inside capillaries
36
An increase in hydrostatic pressure causes an increase in?
BP
37
What is cardiac tamponade?
Built up fluid in the space between the pericardial activity (sac) & the heart
38
Initiation of the HR?
SA node 60-100, AV node 40-60, Purkinjee fiber's 20-40
39
Formula for cardiac output?
SV x HR = CO
40
What is complicated HTN?
Chronic hypertensive damage to the walls of systemic blood cells. Smooth muscles cells undergo hypertrophy & hyperplasia w/ fibrosis of the tunica intima & media. Causes mechanical damage.
41
What is malignant HTN?
Rapidly progressive htn with DIASTOLIC pressure > 140 mmHg
