Abstract :
An optimally controlled respirator was developed. It has three main features: 1) ventilation is controlled by the patient´s metabolic rate from continuously measured C02 output, 2) physiologic dead space approximated as a linear function of tidal volume is used to estimate alveolar ventilation, and 3) respiratory rate is computed to minimize ventilatory work.
