what is osmolality?
the number of particles in a solution per unit liquid compared to blood
what are high osmolality agents? (HOCM)
low osmolality agents? (LOCM)
agents that may have as much as seven times the osmolality of blood
have roughly twice the osmolality of blood
what are Isosmolar agents? (IOCM)

what is viscosity?
what affects viscosity?
thickness or friction of a fluid as it flows
brand, temperature, and concentration affect the contrast media/viscosity

examples?
possess a lower density than the surrounding structures (anatomy)
air, cO2
