WebFick Method (FM) and the Thermodilution method (TD) [11]. Several studies have compared different technologies to measure CO, but only a few studies have tried to answer whether the FM or TD is better in patients with PAH [12]. Recent studies show that there are significant discrepancies between the CO measured by FM or TD [13,14]. We have WebFick estimates were higher than thermodilution estimates at the lower (cardiac index . 2.2 liters/min/m2) and higher (>4.0 liters/min/m2) ends of the cardiac output range.Fick estimates tended to be higher than thermodilution estimates for patients older than 75; the converse was true for those age 65 or younger. show me rec room https://sh-rambotech.com
