Fluids Flashcards
what percent of BW is water
60%
fluid volume of dogs
90 ml/kg
percent of total body weight that is intracellular fluid
60%
what kind of fluid loss is easily measured
sensible
what kind of fluid loss is not easily measured
insensible
maintenance rate
60 ml/kg/day
allometric formula for maintenance rate
Dogs: 132 x body weight^0.75
Cats: 80 x body weight^0.75
formula for replacement rate
% dehydrated x body weight in kg x 1000 (to get to mL from L) = total mls
formula for ongoing loss
(estimated loss / hrs) x 2 = ml/hr
total fluid rate formula
total fluid rate = maintenance rate + replacement rate + ongoing loss rate
small molecule fluid type
crystalloids
what fluid type is used for dehydration, shock, interstitial space
crystalloids
three divisions of crystalloid solutions
hypotonic
isotonic
hypertonic
crystalloid solution that is a balanced electrolyte solution, similar to the osmolality of the patients plasma
isotonic
crystalloid solution that has a sodium content and osmolality less than extra cellular fluid
hypotonic solution
