Thermodilution may support CI monitoring as a practical alternative post-revascularization; leaves open validation in broader or high-output cohorts.
Does the thermodilution technique provide comparable cardiac index measurements to the direct Fick method in patients following myocardial revascularization?
Thermodilution provides cardiac index measurements that are reasonably close to the direct Fick method in most post-cardiac surgery patients, though discrepancies >0.5 L/min/m2 occur in about a quarter of cases.
Hodges et al. (1975) studied this question.
