Error in thermodilution cardiac output measurement caused by variation in syringe volume.
It is important to measure the exact volume of 5% dextrose injected when thermodilution cardiac output determinations are made. The marked volume on plastic syringes and their variability may contribute to a small but significant error in the results.
