SEROUS FLUID Flashcards
Fluid between the membrane’s w/c provides lubrication as the surfaces move against each other.
serous fluid
serous fluid is formed as ________
ultrafiltrate of plasma
function of serous fluid
Provides lubrication as the surfaces move
against each other
source of serous fluid
Ultrafiltrate of plasma; fills organ cavities
normal appearance of serous fluid
clear and pale yellow
Closed cavities
PLEURAL, PERICARDIAL, PERITONEAL
PLEURAL, PERICARDIAL, PERITONEAL are lined by 2 membranes known as serous membranes
Parietal Membrane
Visceral Membrane
lines the cavity wall
Parietal Membrane
cover the organs w/in the cavity EFFUSION
Visceral Membrane
an increase in fluid between the membranes
due to disruption of the mechanisms of serous fluid formation & reabsorption.
EFFUSION
causes of effusions
increase hydrostatic pressure
decrease oncotic pressure
increase capillary permeability
lymphatic obstruction
increase hydrostatic pressure =
congestive failure
decrease oncotic pressure =
hypoproteinemia
increase capillary permeability =
inflammation and infection
lymphatic obstruction =
tumor
usual amount by needle aspiration (serous fluid)
100 mL
procedure/collection for pleural (ser.f)
thoracentesis
procedure/collection for pericardial (ser.f)
pericardiocentesis
procedure/collection for peritoneal (ser.f)
paracentesis
tube used for cell counts & differential count in ser.f
EDTA tube
for chemical serologic, microbial & cytologic analysis (syn.f)
Heparinized (green-top evacuated tubes)
Specimens for pH must be maintained ______ in _____.
anaerobically ; ICE
