1
Q
Height conversion
A
1 inch = 2.54 cm
2
Q
Weight conversion
A
1 kg = 2.2 lbs
3
Q
Surface Area
A
4
Q
Target Blood Flow
A
Target CI x Surface Area
5
Q
Hematocrit (HCT)
A
RBCV / TCBV (%)
6
Q
Total Circulating Blood Volume (TCBV)
A
Female: 70 x Weight in kg
Male: 75 x Weight in kg
Units: mls
7
Q

%
A
8
Q
Heparic Loading Dose
A
(300-400 units/kg) x (Weight in kg)
9
Q
Voulme of Heparin
A
(Loading Dose in units) x (Heparin conc.)
Units are mls and [Heparin] will be given
10
Q
Heparin Dose Response Curve
A
- Slope of line once graphed
- Units of sec/units/kg
- Shows how much additional Heparin needed
- Shows how much Protamine needed
11
Q
Additional Heparin administration
A
- Determine diff between Target ACT and Actual ACT
- Divide difference by Heparin Response Curve slope
- Mulitpl by patient’s weight
- Round up to next whole “thousand”
12
Q
Protamine administration
A
- (Actual ACT - Baseline ACT) / slope
- Multiply by pateint’s weight
- Divide by 100 (converts units to mg)
- Multiply by 1.3 (ensures complete reversal)
