ICU: Swan data display

After the earlier readings above, patient was suctioned and given neb. albuterol...the following readings were observed.

Question: Why is the Cardiac Output higher with lower PA saturations?!

This telemetry trace shows drop in systemic oxygen saturation at the same time as well. Therfore, the A-V difference of saturations (between pulse ox & PA sat from Swan-Ganz) actually narrowed during this time. Therefore, the CO increased.

Patient also became tachycardiac following this which also contributes to increase in CO.
