Bunburaphong P Cardiac output measurement has a significat role in the critical care setting. The standard of
mesurement currently is
via
pulmonary arterial catheter but it has some technical difficulties and serious
complications. The authors performed a new method of measurement that used a catheter in a femoral
artery. The results of both methods performed simultaneously in 10 surgical intensive care patients
every 2 hours for 24 hours were compared. There was high correlation between the two methods, r
=
0.97. The average difference of the cardiac output values was 0.46 1/min with standard deviation 0.56
1/min.
