Figure 1 Changes in Ventilatory Function During Exercise After Fenestration Closure
Fenestration closure-associated changes in each individual patient's minute ventilation/carbon dioxide elimination (VE/VCO2) slope (A), end-tidal partial pressure of carbon dioxide (pCO2) at the ventilatory anaerobic threshold (B), and end-tidal partial pressure of oxygen (pO2) at the anaerobic threshold (C). The VE/VCO2 slope fell in every patient. The end-tidal pCO2 rose and the end-tidal pO2 fell in 19 of 20 patients. Post = post-fenestration closure; Pre = pre-fenestration closure.
