Figure 3
Changes of tidal volume, respiratory rate, electrical activity of the diaphragm, and weaning indices in relation to pre D in failure ( n = 6) and success ( n = 12) patients. The figure shows the median differences between D(f) and pre D, D(l) and pre D, and post D and pre D for tidal volume (VT), electrical activity of the diaphragm (EAdimax), respiratory rate (RR), and derived indices (RR/dEAdi, VT/dEAdi, and RR/VT) for failure and success patients. Dark columns show failure patients; light columns, success patients.
