Edema & Shock- Lecture Flashcards
The most important starling force in driving edema is _
The most important starling force in driving edema is capillary hydrostatic pressure
The capillary oncotic pressure is mainly about _ ; it can be affected by:
The capillary oncotic pressure is mainly about albumin ; it can be affected by:
* Kidney disease
* Diabetes
* Liver disease
Anything that might disrupt our capillary endothelium like _ or _ can lead to leaky capillaries and fluid
Anything that might disrupt our capillary endothelium like bacteria or burns can lead to leaky capillaries and fluid
Shock is a clinical state in which _
Shock is a clinical state in which tissues don’t receive adequate blood flow and thus O2 to meet their metabolic demand
Name two equations to calculate MAP
MAP = 2/3 DBP + 1/3 SBP
MAP = CO * SVR
CO = SV * HR
We can use _ tool to determine the pulmonary capillary wedge pressure and estimate our _
We can use Swann catheter to determine the pulmonary capillary wedge pressure and estimate our LAP
During all types of shock, oxygen extraction exceeds oxygen delivery; how do different types of shock differ?
During all types of shock, oxygen extraction exceeds oxygen delivery..
Hypovolemic shock: problem with preload
Distributive shock: problem with afterload
Cardiogenic shock: problem with contractility
Distributive shock:
Preload is (increased/ decreased)
Afterload is (increased/ decreased)
Cardiac output is (increased/ decreased)
Distributive shock:
Preload is decreased
Afterload is decreased
Cardiac output is increased
Hypovolemic shock:
Preload is (increased/ decreased)
Afterload is (increased/ decreased)
Cardiac output is (increased/ decreased)
Hypovolemic shock:
Preload is decreased
Afterload is increased
Cardiac output is decreased
Cardiogenic shock:
Preload is (increased/ decreased)
Afterload is (increased/ decreased)
Cardiac output is (increased/ decreased)
Cardiogenic shock:
Preload is increased
Afterload is increased
Cardiac output is decreased
Obstructive shock (MECHANICAL):
Preload is (increased/ decreased)
Afterload is (increased/ decreased)
Cardiac output is (increased/ decreased)
Obstructive shock (MECHANICAL):
Preload is decreased
Afterload is increased
Cardiac output is decreased
Obstructive shock (PE):
Preload is (increased/ decreased)
Afterload is (increased/ decreased)
Cardiac output is (increased/ decreased)
Obstructive shock (PE):
Preload is LV decreased, RV increased
Afterload is increased
Cardiac output is decreased
Treatment for hypovolemic shock is _
Treatment for hypovolemic shock is fluids
Treatment for cardiogenic shock is _
Treatment for cardiogenic shock is dobutamine
* Fluids can be very dangerous
Treatment for neurogenic distributive shock is _
Treatment for neurogenic distributive shock is NE, phenylephrine
