ABSTRACT:
A filter having a microporous hydrophilic membrane is utilized in a thermodilution set up wherein the filter is positioned downstream from the injectate reservoir, the syringe and most of the fittings through which bacteria or other harmful materials could enter the bolus of injectate. The filter thus traps bacteria and particulates and prevents the material that may have inadvertently entered the injectate stream from being introduced into the patient. The filter is relatively inexpensive and is commerically available having a pore size of about 0.2 um while allowing typical thermodilution injectate flows of about 150 cc/min.
