IV fluids and blood component therapy Flashcards
makes up approximately 30-40% of body water or 28 L
intracellular fluid
where is a large amount of intracellular fluid found?
skeletal muscle
extracellular fluid:
body water outside cells 20-25% BW or 15L
two types of extracellular fluid
intravascular volume
interstital volume
intravascular volume:
plasma portion of blood
4.3% of BW or 3L
interstitial volume:
fluid between the cells
15.7% BW or 12L
EBW for average adult male
70 ml/kg
EBW for average female
65 ml/kg
EBW for obese patients
55 ml/kg
formula for fluid replacement:
deficit + maintenance + insensible +blood loss =hourly replacement
how to calculate EBV
EBW x KG
how much crystalloid would you give for 1 ml blood loss
3 ML
how much colloid would you give for 1 ml blood loss
2ml
how much blood would you give for 1 ml blood loss
1 ml
lap sponges hold how many CC of blood
100-150 ml
minimal moderate and extreme insensible loss:
4ml/kg/hr
6 ml/kg/hr
8 ml/kg/hr
how to calculate the deficit:
multiply number of hours NPO by maintenance
two ways to calculate the allowable blood loss
20% of EBV or
calculate EBV x (hemoglobin initial - hemoglobin allowable (bleed out) dividied by hemoglobin initial
