Iv 1 Flashcards
2 basic compartment
Intracellular
Extracellular
Intracellular
Fluid within the cells
Extracellular
Outside cells2 tyes intravascular and interstitial
Intravascular
Fluid within the blood vessels
Interstitial
Fluid within the tissues
How much water in you
40% intracellular
20% extracellular
Fluids dont remain
Static, it moves around through passive and active transport
( no energy required to move)
Types of passive transport in fluids
Diffusion
Osmosis
Filtration
Osmolality
Solute concentration by weight (kg)
Osmolarity
Fluid number by msom per lier per solution
Normal osmolality if plasma
Optimal body function occurs when osmolality is close to
270-300 msom/L
300 msom/l
Osmolality less than 270 ms/l is
Hypotonic
Osmolality greater than 300 msom is
Hypertonic
Iv fluids for fluid replacement are
Colloids and crystalloids
Colloids
Large molecules that dont pass through senipermeable membrane. If infused they remain in the intravascular compartment and expand intravascular colume by drawing fluid from extracascular spaces
