Over the years, I’ve used many types of fluid warmers from rapid infusers like the Belmont and Level 1 to more conventional products like the Ranger series. The priming process is somewhat different for each product, but regardless, I always want to make sure I can place a 3-way stopcock between the patient and the device.

Typically these lines are connected to the best access a patient has – a central line or large bore peripheral IV catheter. By having a stopcock situated close to the patient, the line can also be used to bolus medications. Furthermore as a safety measure, I turn the stopcock “off” if I’m worried about inadvertently bolusing a large volume of fluid during tenuous situations (ie, impending right ventricular failure).
