Study Notes
Fluid Compartments
- Intracellular fluid (ICF) is the fluid located inside the cell
- Extracellular fluid (ECF) is the fluid found in arteries and veins, carrying plasma, blood products, and nutrients
- Interstitial fluid is the fluid found in the interstitial spaces, often seen as edema
Osmosis and Diffusion
- Osmosis is the movement of water molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration
- Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration, without the need for energy input
Fluid Movement and Pressure
- Hydrostatic pressure is the pressure exerted by fluid against the walls of a blood vessel
- Oncotic pressure is the osmotic pressure exerted by proteins in blood plasma
- The primary driving force behind the movement of fluids within the cardiovascular system is the hydrostatic pressure gradient
- The primary determinant of mean arterial pressure (MAP) is the systemic vascular resistance
Edema and Compartment Syndrome
- Edema is the collection of water in the interstitial space
- Compartment syndrome is the increase in edema in a compartment, leading to decreased blood flow distal to the injury
- Localized edema can be deadly if not addressed promptly
IV Fluids and Treatment
- Normal Saline (0.9% sodium chloride) is called "normal" because it has an osmolarity close to that of blood plasma
- Hypertonic IV fluids are used to treat hypotension and to reduce cerebral edema
- The primary treatment goal of using hypertonic IV fluids is to increase blood pressure and improve cardiac output
Miscellaneous
- The 5 P's of compartment syndrome are pain, paralysis, paresthesia, pallor, and pulselessness
- Mean arterial pressure (MAP) is the average pressure in the arterial system
- Systemic vascular resistance is increased through vasoconstriction
