Intermittent Volume / Time
This
Intermittent Volume / Time Mode
lets you specify a delivery volume for a specific delivery time, after which the
delivery stops for a programmed interval … then the pattern recycles. In other words, the pump delivers for a set
period, then pauses a set period, then infuses for a set period, and so on.
•
The
delivery stop interval
equals “
Time Between Starts
” minus “
Delivery Time
.”
•
The pattern
repeats
at “Time Between Starts” interval.
