Characteristics of the RIP, using the 3D-HRM assembly. Determination of the respiratory inversion zone using the ‘PIP tool’ of the Manoview software (‘diamond shape’ at 42.5 cm). The transition from a clearly thoracic pattern with inspiratory pressure decrement at 42 cm to a clearly abdominal pattern at 43 cm with a clear inspiratory augmentation occurred gradually, centered at 42.5 cm. In this example, the overall length of the zone was 0.9 cm, otherwise varying between 0.7 and 1.0 in the subject group as a whole.
