Good lecture Bob, pleased you mentioned the worst mode for weaning or reloading muscles is SIMV. Having more intelligent modes where the computer in the ventilator and with intelligent algorithms can help such as AVM or ASV (where a minimum minute guaranteed is required) and have some of the benefits where you cant give the patient full support are much better than these older modes where there is a lot of human era with regards adjusting the ventilator. These modes plus Nava and PAV are really the future in patient management.
