From: Anaerobic threshold, is it a magic number to determine fitness for surgery?

Figure 9

Pulmonary vascular resistance vs. V ˙ e / V ˙ O 2 . All patients in this study had an AT of 10 ml.min−−1 or less. The graph shows the large variation in pulmonary vascular resistance with a V ˙ e / V ˙ O 2 of greater than 35. To be certain that the pulmonary vascular resistance will exceed 35 kPa.L-1.s, the Ve / V ˙ O 2 needs to be greater than 45. Note the PVRI of those patients with a V ˙ e / V ˙ O 2 of 35. Data from the author’s laboratory.
