Your patient is receiving 25 000 units of heparin in 5% glucose 500 ml at 20 ml/h via a volumetric pump. How many units per hour is the patient receiving? The patient’s activated partial thromboplastin time (APTT) result comes back at 32 seconds and the heparin infusion is increased to 35 000 units/500 ml running at 20 ml/h. How many units per hour is the patient now receiving? How many drops per minute (dpm) does this correspond to if a macro-drip is used?
