1. A method for delivering a target volume of fluid to a destination, the method comprising:
- using a user interface configured to allow user selection of a mode from a plurality of user selectable modes, one of the user selectable modes being a low volume delivery mode which limits the target volume to a predetermined range;
selecting, using the user interface, one of the plurality of user selectable modes;
acting pneumatically, with a flow control module to direct fluid flow through a delivery set, the delivery set having one or more pumping chambers and valve arrangements for controlling fluid communication throughout the delivery set;
controlling with a controller how much of the fluid is delivered to the destination, controlling the valve arrangement, and controlling the fluid control module, the controller executing the selected mode of the plurality of user selectable modes; and
wherein upon selection of the low volume delivery mode, controlling with the controller, the flow control module such that the flow control module delivers a first volume of the fluid to the destination and a second volume of the fluid to the destination, the sum of the first volume of the fluid and the second volume of the fluid approximately equal to the target volume, and controlling with the controller the flow control module, such that the flow control module delivers the first volume of the fluid in increments each having approximately a first incremental volume, and delivers the second volume of the fluid to the destination in increments each having approximately a second incremental volume, the second incremental volume being less than the first incremental volume.

Abstract
A method for delivering a target volume of fluid to a destination is provided. The method includes delivering a first volume of fluid to the destination in increments each having approximately a first incremental volume, the first volume of fluid being less than the target volume and delivering a second volume of fluid to the destination in increments each having approximately a second incremental volume, the second incremental volume being less than the first incremental volume, such that the sum of the first volume and the second volume is approximately equal to the target volume.

11. A method for delivering a target volume of fluid to a destination, said method comprising:
-
acting upon a delivery set via a flow control module to deliver the fluid; selecting via an interface a desired delivery mode from a plurality of delivery modes, the plurality of delivery modes including a low volume delivery mode; controlling with a controller the flow control module such that the flow control module behaves as prescribed by the desired delivery mode of the plurality of delivery modes; and wherein upon selection of the low volume delivery mode, controlling with the controller the flow control module, such that the flow control module delivers a first volume of the fluid to the destination and a second volume of the fluid to the destination, the sum of the first volume of the fluid and the second volume of the fluid approximately equal to the target volume, and controlling with the controller the flow control module, such that the flow control module delivers the first volume of the fluid in increments each having approximately a first incremental volume, and delivers the second volume of the fluid to the destination in increments each having approximately a second incremental volume, the second incremental volume being less than the first incremental volume. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for delivering a target volume of fluid to a destination, the method comprising:
-
acting pneumatically upon a delivery set via a flow control module to direct fluid flow through the delivery set, the delivery set having at least a first pumping chamber having a first chamber volume, a second pumping chamber having a second chamber volume, and valve arrangement for controlling fluid communication throughout the delivery set; controlling with a controller how much of the fluid is delivered to the destination, the valve arrangement, the flow control module, the controller configured to operate in; a first mode commanding the flow control module to conduct a number of pumping strokes to pump the fluid from the first or the second pumping chamber, each pumping stroke delivering approximately the respective volume of the first pumping chamber or the second pumping chamber; and a targeting mode, the targeting mode commanding the flow control module to perform one or more targeting strokes, each targeting stroke delivering a predetermined portion of the respective volume of the first pumping chamber or the second pumping chamber; wherein the predetermined portion delivered by each targeting stroke is less than the volume of the first pumping chamber or the second pumping chamber delivered with a pumping stroke. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
