Description
Summary:The largest TF m generated by either maneuver was median 55% (IQR 43-86%, 5th percentile 30%) (Figure 1). di,max Conclusions Thickening fraction of the diaphragm can feasibly be measured during sniffing and maximal Müller maneuvers in healthy subjects; values during maximal inspiratory maneuvers were significantly higher than those obtained under resting conditions. [...]both maneuvers should be attempted in order to measure TFdi max.
