Lecture | Part 1 Hemodynamic Disorder Flashcards
governed by several forces in the blood vessel wall intravascular volume.
Fluid dynamics
Fluid exits through
arterial vascular compartment/end
Fluid returns through
venous vascular compartment/end
pushing force
hydrostatic pressure
pulling forces
oncotic or osmotic pressure
what happens in hydrostatic pressure
Fluid exits through arterial vascular compartment
what happens in oncotic (osmotic) pressure
Fluid returns to venous vascular compartment
level where pushing forces are about equal to the pulling forces.
At the capillary level
pulling forces so water from the interstitial space are pulled into the intravascular volume
oncotic or osmotic pressure
pushing pressure that promote water out of the blood vessel and into the interstitial space
hydrostatic pressure
behavior of water across compartments and to a certain extent blood. eg, Congestion hyperemia
Hemodynamic Disorders
in blood vessel there is hemostasis and if there is disturbances it may lead to clotting of the blood
Thromboembolic Disease
circulatory collapse
shock
increased fluid in the ECF
Edema
increase in blood blood flow in the arteriolar end
Hyperemia
increase in the backflow at the venus end
Congestion
extravasation of blood
Hemorrhage
blood is within the intravascular compartment if it goes out of the intravascular compartment it is now called
Hemorrhage
keeping keep the blood flowing in the intravascular space
Hemostasis
conditions that can cause clotting of blood
Thrombosis/thrombus formation.
From the adhered blood vessel, clotted blood is detached from the thrombus and travel across the blood vessels it will essentially be called
embolus
death of tissues due to lack of blood
Infarction
death of tissues due to decreased delivery of oxygen and this will cause cellular hypoxia
Infarction
circulatory failure/collapse
Shock
lack of perfusion to the different organs of the body
shock
4 possibilities of EDEMA
- Increased Hydrostatic Pressure
- Reduced Oncotic Pressure
- Lymphatic Obstruction
- Sodium/Water Retention
composes 60% of body
water
2/3 of body water is
intracellular
1/3 of body water is
interstitial
Only 5% water is
Intravascular
shift of water to the interstitial space
edema
water filling in the thoracic cavity
Hydrothorax.
water inside the pericardial space or pericardial cavity
hydropericardium
general term of fluid accumulating in the body cavities
Effusion
accumulation of water that involves the peritoneum
ascites
presence of water in the peritoneal cavity
ascites
generalized edema
anasarca
accumulation of fluid in the soft tissues in the body cavities
anasarca
total body water volume
40 liters, 60% body weight
25 liters, 40% body weight
Intracellular fluid volume
15 liters, 20% body weight
extracellular fluid volume
