Do you favor the use of Fick or thermodiluation to measure cardiac output in patients with interstitial lung disease with suspected pulmonary hypertension?   

Unless the patient has a left to right shunt or a metabolic cart is used to calculate direct Fick, thermodilution cardiac output (TDCO) is the preferred method of cardiac output measurement in all patients with pulmonary hypertension. This is supported by current guidelines. It's important to take t...

I completely agree with all of the above. There are too many assumptions during the indirect Fick CO calculation, including which formula will be used to estimate O2 consumption. Similarly if at any point an exercise challenge is undertaken, once again TD CO would be the more accurate measurement.&n...
