Injectors, Thermal Dilution
Definition : Injectors designed to administer bolus injections of indicator solution (e.g., cooled saline solution) into the heart; providing rapid and consistent injections. These devices typically consist of a pressurized gas system and an electromechanical switch that directs the gas to a piston that delivers the solution into a syringe that in turn injects it through a balloon catheter into the right atrium of the heart. Thermal dilution injectors are used for reproducible cardiac output measurements in cardiac catheterization laboratories and critical care units; they can also be used for determination of cardiac output by injecting a dye and performing a similar indicator-dilution technique.
