Clinical Usefulness of Response Profiles to Rapidly Incremental Cardiopulmonary Exercise Testing
Figure 10
Exertional oscillatory ventilation (EOV) during incremental CPET in a 56-yr-old male with severe CHF. EOV was defined by regular (standard deviation of three consecutive cycle lenghts within 20% of their average) and ample (minimal of 5 L/min) cycles of ventilatory oscillations [27]. A similar oscillatory pattern is also seen in oxygen uptake and carbon dioxide output .
