Fluid compartments
ICF and ECF
Compartment where all fluids are inside the cell
Intracellular Fluid (ICF)
Compartment where fluids are outside the cell
Extracellular Fluid (ECF)
Fluids between cell (third space) blood, lymph node, bone, connective tissue, water
interstitial fluid
Accumulation and sequestration of trapped extracellular fluid in actual or potential body space as a result of disease or injury
third space
Refers to fluid inside blood vessel
intravascular
Body of fluid that is not inside the cell but is separated from plasma and interstitial fluid by cellular barriers.
transcellular
Excess accumulation of fluid in the interstitial space; occurs as a result of alterations in oncotic pressure, hydrostatic pressure, capillary permeability, and lymphatic obstruction.
edema
Generalized edema, excessive accumulation of fluid in ther interstitial space throughout the body occurs as a result of conditions such as cardiac, renal, or liver failure.
anasarca
Factors that affect water distribution
age, sex, fluid type, fluid movements, balancing fluids
Fluid type that has the same osmolarity to body fluid.
isotonic solution
Fluid type that has the same salt concentration as cells and blood
isotonic solution
Fluid type that has lower concentration of salt or solute than another, more concentrated solution
hypotonic solution
A solution that contains fewer dissolved particles (salt and other electrolytes) than is found in normal cells and blood
hypotonic solution
This solution is commonly used to give fluids intravenously to hospitalized patients in order to treat and avoid dehydration.
hypotonic solution
Fluid type that has higher concentration of solutes than other, less concentrated solution, higher osmolarity than fluid
hypertonic solution
A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
hypertonic solution
Solute (substance dissolved) may spread through a solution/solvent (solution where solute is dissolved)
diffusion
Movement where solute spreads higher to lower concentration
diffusion
It is the process of moving molecules across a cellular membrane through the use of cellular energy
active transport
It is the pressure in the force that draws solvent in less concentrated solute through a high concentrated.
osmosis
It is where fluid generally moves out of the capillary and into the interstitial fluid
capillary filtration
Ways to balance fluids
thirst, kidneys, ADH, RAAS, Anti-natriuretic peptide
What works with fluids to maintain health and well being?
electrolytes
What is crucial for nearly all reactions and functions of the cell?
electrolytes
It is an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons
ion
Generates a negative charge
anion
Generates a positive charge
cation
Positive and negative ions balance each other out, achieving neutral electrical charge
electroneutrality
Functions of electrolytes:
Regulate ______
Govern _____
Transmit _____
Contributes _____
Regulate water distribution
Govern acid-base balance
Transmit nerve impulses
Contributes on energy generation and blood clotting
Major EC Electrolytes
Sodium, Chloride, Calcium, Bicarbonate
This helps maintain normal blood pressure, supports the work of your nerves and muscles, and regulates the body’s fluid balance.
sodium
What are the food sources of sodium?
Bacon, frankfurters, lunch meat, butter, cheese, canned food, ketchup, mustard, milk, processed food, snack food, soy sauce, table salt
Causes of HYPONATREMIA
Increased Na excretion
Inadequate Na intake
Dilution of serum Na
Factors that affects increased Na excretion
Excessive diaphoresis, Diuretics, Vomiting, Diarrhea, wound drainage especially GI, Kidney disease, decreased secretion of aldosterone
Factors that affect inadequate Na intake
NPO-fasting, L Na diet
Factors that affect dilution of serum Na
Excessive ingestion of hypotonic fluid or irrigation with hypotonic fluid, kidney disease, freshwater drowning, SIADH secretion, Hyperglycemia, Heart failure
What is needed to monitor in HYPONATREMIA?
Cardiovascular, RR, Neuromuscular, cerebral, renal, GI
HYPONATREMIA is accompanied by _____
fluid volume deficit (hypovolemia)
What is administered to restore Na content of fluid?
IV Na Cl
What is prescribed to promote the excretion of water rather than Na?
osmotic diuretics
What is administered if HYPONATREMIA is caused by inappropriate or excessive secretion of antidiuretic hormone?
medications that antagonize antidiuretic hormone
