Figure 4.
Scatter plot comparing the calculated PVR from measured oxygen consumption vs estimated oxygen consumption using the Dehmer calculation. Of the HF patients, 16% (113/691) have a PVR of <3 Woods units using the Dehmer calculation while PVR >3 Woods units using the measured oxygen consumption (right lower quadrant). 1% (7/691) have a PVR of <3 Woods units using the measured oxygen consumption formula while PVR >3 Woods units using the Dehmer calculation (left upper quadrant).
