E exposure
fluid between ICF and ECF compartments is due to what force
osmotic forces
fluid within the ECF, between interstitial and intravascular is due to what forces
starling forces
VEP of isotonic fluids?
redistribution?
25%
redistributes to ECF
VEP of hypertonic fluids?
redistribution?
500%
all compartments
VEP of hypotonic fluid?
redistribution?
8.3%
ICF anf ECF
colloids VEP?
redistribution?
80-120%
intravascular
maintenance formula
70 x BW (kg)0.75 = mL/day (dogs/cats)
132 x BW (kg)0.75 = mL/day (dog only)
how much do you give to account for ongoing losses?
1/2-1x maintenance
dehydration deficit in Liters
%dehydrated x BW(kg)
isotonic fluid shock dose in dogs
80-100 mg/kg
hypertonic fluid shock dose in dogs
5 ml/kg
colloids shock dose in dogs
20 ml/kg
blood products shock dose in dogs
20 ml/kg
how much of a shock dose do you give initially and over how long?
1/4 shock dose (10-20ml/kg)
over 5-30 mins
main causes of hypernatremia
no access to water
CNS disorders (hypodypsia)
salt intoxication
main cause of hyponatremia
ADH secretion due to hypovolemia
treatment of hypernatremia
treat primary cause
hypotonic fluids (D5W)
what is the formula for how much water to give with a hypernatremic patient?
Water deficit = 0.6 x BW(kg) x [(
Patient Na/Normal Na) - 1]
treatment of hyponatremia
what is the formula for Na?
treat primary cause
give Na =
(Fluid Na - Patient Na)/(0.6 x BW) + 1
do you want to treat hyper/hyponatremia rapidly or slowly? what do you want to not exceed in mmol/L/hr?
slowly
0.5 mmol/L/hr
main causes of hyperkalemia
oliguria/anuria
urinary obstruction/rupture
addison’s
psuedohypoaldosteronism
main causes of hypokalemia
diuretics
renal insufficiency
vomiting and diarrhea
treatment for hyperkalemia
insulin
dextrose
bicarb
Ca gluconate
treatment for hypokalemia
supplement with KCl
what views can you see on AFAST
CVC collapsibility
CVC:Ao ratio
is CVC collapsibility or CVC:Ao affected by the resp cycle?
CVC collapsibility
causes of hypoxemia
low PiO2
high PCO2
low V/Q
no V/Q (shunt)
diffusion impairment (pulmonary fibrosis)
normal pH?
7.4
normal urine output
1-2 ml/kg/hr
