Flow Rate Calculator Instructions

The flow rate calculator for EMED Technologies flow control devices, is a tool designed to assist clinicians in the selection of infusion products and their appropriate settings to ensure a safe and comfortable infusion experience. Follow these easy steps to use and understand the online flow rate calculator.


Select your country or region


Select infusion drug & enter dosage amount in milliliters

NOTE: Ensure that you are familiar with the prescribing information for your drug applicable to your country.

Some drugs also require information about the patient's age or weight. Select the appropriate patient information if the dropdown box appears.


Select the type of infusion

For people performing infusions for the first time, select Initial Infusion. For people performing regular or maintenance infusions, select the Maintenance Infusion option.


Select your infusion pump


Select an appropriate needle set

  • Needle gauge

  • Number of needles

  • Specific needle set code


Select the flow control device

For fixed rate control, select Infuset, and for variable rate control, select either VersaRate or VersaRate Plus.

  • For variable flow control: Select flow controller position setting


  • For fixed flow control: Select specific Infuset code

Understanding Your Infusion Results

Total flow rate

This value represents the average total flow rate of your drug which is delivered to all of your infusion sites combined during the full duration of the infusion. It is shown in milliliters per hour (mL/hr).

Flow rate per site

This value represents the average flow rate of your drug delivered to each of your infusion sites individually during the full duration of the infusion. It is shown in milliliters per hour (mL/hr).

Dosage volume per site

The dosage volume per site is the volume of drug (in milliliters) that will be supplied through each needle to each of your infusion sites.

Infusion time

The infusion time is the expected duration that your infusion therapy session will take.

Notes and Warning Messages

The flow rate calculator has been designed to warn the user when the combination of selected infusion products may exceed the prescribing limits for the chosen drug. Depending on the type of infusion selected, these warnings may appear when exceeding either the total flow rate for all needle sites combined, the flow rate limit per needle site, and the dosage volume allowed per needle site. Warning messages will appear in red in the Infusion Results section.

Warnings and cautions regarding flow rate and volume limitations are based on recommendations made by the drug manufacturer of the selected drug and may be subject to change. All reasonable attempts are made to ensure that this calculator contains the most recent drug related information, but it is the user's responsibility to ensure familiarity with the relevant drug and its most recent instructions for use for their particular country before using this calculator.

NOTE: The flow rates shown in this tool shall be used as a guide/reference only to illustrate the capabilities of the flow control/regulator sets when used to infuse the selected drug in combination with the selected parameters. These are a representation of expected values using the SCIg60 Infusion System based on testing at room temperature between 20°C - 25°C (68°F - 77°F), and may vary based on different needle lengths, fluctuations in temperature (which significantly affects the viscosity of the selected drug), large height differences between the infusion pump and infusion site, and patient anatomy. Flow rates shown represent an average expected flow rate, and may in some cases, for the VersaRate and VersaRate Plus, be lower or higher by up to ±40% at position settings 1-2, up to ±20% at position settings 3-4 and up to ±15% at higher position settings. This is a typical range of variability for these types of adjustable flow control devices. For the Infuset fixed rate controller, average flow rates may be higher or lower by up to ±15% due to system tolerance and the sources of variation already mentioned.
