Module 2 ACOLS Flashcards
Diffusion is the migration of particles from higher to lower
T
Osmosis is the movement of water molecules that occur in one direction across a semi permeable membrane
T
Colloid osmotic pressure of the plasma (COPpl) is the force of proteins in the blood to hold water
T
Blood pressure in the arteries is higher than blood capillary pressure
T
In healthy individuals the colloid osmotic pressure of proteins located in the interstitium (COPip) is greater than the Colloid osmotic pressure of the plasma (COPpl)
F - less
The precapillary sphincter is innervated by the sympathetic portion of the Autonomic Nervous System (ANS)
T
The precapillary sphincter dilates = Less blood into capillaries —> less volume = decreased blood capillary pressure (BCP)
F - more blood, more volume, increased BCP
Starlings Law states that the average Blood capillary pressure (BCP) equals the average Colloid Osmotic Pressure of the plasma proteins (COPpl)
T
Complete Decongestive Therapy (CDT) attempts to restore normal diffusion distance and prevent re-accumulation of fluid
T
The Functional Reserve (FR) of the lymphatic system enables the lymphatic system to respond to an increase in lymph fluid volume with and increase in Lymph Time Volume (LTV)
T
if the normal diffusion distance in the tissues between the cells and the blood capillary increases (swelling present)
The local immune response in the tissue cells is compromised
The nutritional supply to the cells will suffer
Patient is prone to frequent infections
What is true about diffusion distance
Swelling increases Diffusion Distance
If swelling is present immune response is low/ compromised and nutritional supply suffers
Compression decreases diffusion distance
When the precapillary sphincter located at the arteriole contracts
- less blood enters into the capillaries
- volume will decrease and the blood capillary pressure will also decrease
- less filtration occurs
What upsets The equilibrium of Starlings Law?
Passive hyperemia
Active hyperemia
If a healthy lymphatic system is overwhelmed and the lymphatic loaf of water exceeds the transport capacity (TC) with a Lymph Time Volume (LTV) maxed out is called…
Dynamic Insufficiency
Define: Hypoproteinemia
Abnormal deficiency of the amount of protein in the blood
Mechanical insufficiency
Transport capacity drops below the normal amount of lymphatic load, low volume insufficiency
Filtration
Transport of a solution through a filter, provided the membrane is permeable
Lymphedema
Abnormal accumulation of protein rich fluid in the tissue
Functional reserve
Back up of lymphatic system - amount of compensation
Edema
Abnormal accumulation of water in the tissue
Dynamic insufficiency
Healthy lymphatic system is overwhelmed, Hugh volume insufficiency
Transport Capacity
The maximum amount of lymph transported with the lymphatic system working as hard as possible in a given length of time
Lymph time volume
Amount of lymph transported in a unit of time
Reabsorption
Process by which water is reabsorbed from the tissues back into the venous end of the blood capillary
