ADJUSTMENT OF I.V. HEPARIN DOSE APTT RATIO

INFUSION RATE CHANGE

> 7

STOP FOR 30 min – 1 hr and reduce by 500 units/hr (1 ml / hr)

5.1 – 7.0

Reduce by 500 units/hr ( 1 ml / hr )

4.1 – 5

Reduce by 300 units/hr ( 0.6 ml / hr )

3.1 – 4

Reduce by 100 units/hr ( 0.2 ml / hr )

2.6 – 3

Reduce by 50 units/hr ( 0.1 ml / hr )

1.5 – 2.5

NO CHANGE

1.2 – 1.4

Increase by 200 units/hr ( 0.4 ml / hr )

< 1.2

Increase by 400 units/hr ( 0.8 ml / hr )
