Yes. The blood products should be stopped during cardiac output measurements.
output measurements depend upon stable
INJECTATE and BLOOD temperatures. Administration of cold blood products
through the introducer, VIP or paceport lumens will lower the temperature
of the blood in the right atrium. When cardiac output injections
are performed, the change in temperature may be greater than predicted
for the volume of solution used; a false cardiac output reading may be
