| Abstract: | Making use of closed-loop control for portable medical ventilator can enhance the performance of portable medical ventilator and make it more safe. Using the respiratory mechanics, end-tidal CO2 pressure（PetCO2）, arterial oxygen saturation（SaO2） as feedback signal to control the medical ventilator will improve the therapeutic efficacy, but wouldn＇t affect its applicability. |
