Introduction Flashcards
2 types of fluid loss
INSENSIBLE - from skin & lungs
SENSIBLE - thru elimination, urination, defecation
Functions of Kidney
- Controls BP
- Controls water balance
- Regulate electrolytes
- Regulate acid-base balance
- Regulate RBC production
- Excretion of waste products
- Renal clearance
- Secretion of prostaglandins
- Synthesis of vit. D to active form
- Urine formation
It is the fluid surrounding an organ
TRANSCELLULAR FLUID
ex. CSF, pericardial, synovial, intraocular, pleural
What are the 2 fluid compartments? Describe.
Intracellular fluid (within cell) - 2/3 of body fluids
Extracellular fluid (outside the cell) - 1/3 of body fluid, transports electrolytes, carries substances
Function of body fluids
- Maintain blood volume
- Regulate body temp
- Transport material to & from cellular metabolism
- Assist w/ food digestion
- Medium for excreting waste
Where is ICF primarily located
SKELETAL MUSCLE MASS
Primary solutes found in the ICF
- Glucose
- Electrolytes
- Oxygen
How many percent does of fluid compromises the typical adult weight
60%
Components of ECF
- Intravascular (in blood vessels) - plasma
- Interstitial (bet. cells/surrounding cells)
- Transcellular (fluid in organs)
ECF & ICF contains:
- O2 from the lungs
- Dissolved nutrients from gut
- CO2
- Ions
What are the factors that influence the amount of body fluids
- Age
- Gender
- Fat
Fluid found in the blood vessels
INTRAVASCULAR FLUID
Fluid found between the spaces of the cell / surrounding the cell
INTERSTITIAL FLUID
It is the measurement of BP in the right atrium & vena cava
CENTRAL VENOUS PRESSURE
Other signs and symptoms of third-space fluid shift that indicate an intravascular fluid deficit (FVD)
- Increased HR
- Decreased BP
- Decreased CVP
- Edema
- Increased body weight
- Imbalances in fluid I&O
It is the lost of fluid not contributing to ICF & ECF
THIRD-SPACE FLUID SHIFT
Early s/s of of Third-Space Fluid Shift
Decreased urine output despite adequate fluid intake
These parts of the body contains high amounts of water
- Muscle
- Skin
- Blood
