NORMAL RANGE
1. weight
2. temperature
3. pulse
4. hemoglobin
5. hematocrit
6. age
7. blood pressure

A
  1. weight = 110 lbs / 50 kg
  2. temperature = 37.5 C | 99.5 F
  3. pulse = 50-100 bpm
  4. hemoglobin = >12.5 g/dl | 125 g/L
  5. hematocrit = >33%
  6. age = 18-65 yrs old
  7. blood pressure = 180/100 mmHg

17 y.o needs a parent’s consent 65 y.o needs a physicial consent

Q

volume adjustment

if the blood donor weighs <110 lbs, what should we do? how to solve?

A

decrease the volume of blood collected
