Trans 8 - Fluid and Hemodynamic Derangements Flashcards
Movement of water and low/molecular weight (LMW)
solutes between intravascular and interstitial spaces is
primarily controlled by ________ and ___________
vascular hydrostatic pressure and
plasma oncotic pressure
failure to maintain normal fluid homeostasis results to
edema
normal fluid homeostasis involves
vessel wall integrity
intravascular pressure and
osmolarity within physiologic ranges
clotting at appropriate times
thrombosis
migration of clots
embolism
Inability to form a clot during a vascular injury results in
hemorrhage
most of the extracellular fluid is found in the
interstitium
Right-sided failure results in
peripheral edema
- Impaired venous return or arteriolar dilation
- Exemplified by Congestive Heart Failure (CHF)
increased hydrostatic pressure
left sided failure results in
pulmonary edema
Majority of right-sided heart failure is due to
left-sided heart failure
Left-sided failure may be caused by an obstruction such as a
thromboembolism
leaky glomerular capillaries → proteins including albumin pass through the glomerulus → proteins get excreted through the urine → this will lead to hypoalbuminemia → decreased plasma oncotic pressure
nephrotic syndrome
malfunctioning liver produce
less amount of albumin → hypoalbuminemia →
decreased plasma oncotic pressure
severe liver disease
