CO NCEN TRATI ON P ROFILE
The Concentration flow profile is used to manage infusion of a defined concentration of drug or other
liquid to a set dosage level based on the subject’s weight.
Figure 58: Concentration Flow Pump Operation Profile.
When creating or editing a Concentration flow profile, you will define the following operating parameters:
• The Weight of the target subject
• The Flow Rate to be used during infusion
• The concentration of the drug or other liquid being infused
• Either the target dosage or the target infusion time — the pump automatically calculates whichever
value you do not enter.
• If you wish to infuse multiple doses to the target, you can specify the number of doses along with a
delay between dosings.
During a Concentration profile, the PHD ULTRA
™
operates at a constant infusion rate and automatically
stops when the target dosage rate is reached.
When creating or editing a Concentration flow profile, you can set the rate in ml, µl, nl or pl units of
volume using sec, min or hr as the units of time. The system automatically calculates a minimum and
maximum flow rate based on the syringe selected or custom-defined. The min/max values are made
available as button selection options on the Set Rate and Concentration screen. The ingredient
concentration is entered in mg/ml.
