ABSTRACT:
A ventilator has automatic controls with a particular control sequence to progressively wean the patient from mechanical ventilation, but that detects and maintains the patient's condition against the patient's inability to resume normal respiration. The ventilator non-invasively monitors body oxygen saturation level to insure adequate respiration, with minimum excess oxygen exposure, and monitors exhaled tidal carbon dioxide levels to control mechanically assisted respiration rate.
