Abstract
A method for readying a fluid sensor associated with a medical device includes attaching a flow restrictor to a fluid outlet of the fluid sensor. The fluid sensor includes a fluid channel, a fluid inlet at a first end of the fluid channel configured to couple to an outlet of an administrable fluid source, and the fluid outlet at a second end of the fluid channel. Fluid is delivered from the administrable fluid source to the fluid channel through the fluid inlet. A syringe actuation device including a force limiting device may be used to deliver the fluid. The fluid is pressurized in the fluid channel between the fluid inlet and the flow restrictor to wet an interior surface of the fluid channel with the fluid. The flow restrictor is removed from the fluid outlet.
