I suppose that's good news then for potential emergency use of unapproved makeshift alternatives to ventilators, I guess it also makes hand ventilation viable if you have enough volunteers available to do the bagging.
Anesthesiologist here - true, I was a Stanford medical student on an ICU rotation when a Tesla employee crashed his plane into high voltage power lines while attempting to land at San Carlos airport. Electrical power on the peninsula was out for an extended period of time. Battery backups eventually failed, then gas powered generators started failing so everyone with a pair of hands took turns manually ventilating the patients. If push comes to shove, we could get by with a Jackson-Reese circuit and a pair of hands. Obviously we don’t want to find ourselves in this situation.
