Vet Radar has a calculator for maintenance fluid rate for patients. To calculate fluid rates, Vet Radar uses the information given in Fluids for maintenance and replacement (American Animal Hospital Association, 2013).
This table shows the AAHA equations that Vet Radar uses to calculate maintenance fluid rates for different species:
Species
Equation
Feline
80 × patient's body weight (kg)0.75
Canine
132 × patient's body weight (kg)0.75
Equine
60 × patient's body weight (kg)0.75
Other species
60 × patient's body weight (kg)0.75
Note: The AAHA equations are for daily fluid rates. Vet Radar only shows hourly fluids rates. To calculate and show an hourly fluid rate, Vet Radar divides the result of an applicable AAHA equation by 24.
Note:Vet Radar always uses kilogram as the unit of measurement for weight when it calculates a maintenance fluid rate. It is not necessary to change to a different unit of measurement for weight for Vet Radar to automatically calculate the fluid rate.
The Result section of the IV Fluids treatment pane automatically shows the maintenance fluid rate for a patient after you do these steps:
Select Add treatment.
Select IV Infusion.
Select Go to calculator.
The Result section has three settings that you can use to change the maintenance fluid rate. The example image and the table that follows gives each setting and its function.
Note: The example image shows the maintenance fluid rate of a 10.5 kg canine patient.

Setting
Function
Physiologic Req.
The Physiologic Req. setting shows the maintenance fluid rate of the patient. Vet Radar automatically calculates the Physiologic Req. value.
Note: You cannot change the unit of measurement of the Physiologic Req. setting.
Ongoing Losses
The Ongoing Losses shows the quantity of fluids that the continuously loses (for example, if the patient is continues to vomit). Vet Radar automatically sets the initial Ongoing Losses value to 0.
Note: You cannot change the unit of measurement of the Ongoing Losses setting.
Total
The Total setting shows the total value of the maintenance fluid rate for the patient. To calculate the total value of the maintenance fluid rate, Vet Radar automatically adds Ongoing Losses value to the Physiologic Req. value.
You can change the unit of measurement of the Total setting to:
mL
L
Note: If you change the unit of measurement of the Total setting, Vet Radar does not automatically change the total value of the maintenance fluid rate that the Total setting shows. To change the total value, you must manually change it.
