Room-temperature thermodilution cardiac output: proximal injectate lumen vs proximal infusion lumen.
OBJECTIVE
To assess the accuracy of room-temperature thermodilution cardiac output measurements from the venous infusion port.


METHODS
Central venous port cardiac output measurements were compared with venous infusion port measurements in 48 right-heart catheters.


METHODS
Three 10-mL injections of 5% dextrose in water were made through each port. The order of port injection was random.


RESULTS
The cardiac outputs were 5.8 +/- 1.8 L/min from both ports, with no difference between ports (paired t test).


CONCLUSIONS
Room-temperature thermodilution cardiac output determinations from the venous infusion port can be used in place of central venous port cardiac outputs if the central venous port becomes nonfunctional.
