A system and method for automatically selecting an appropriate oxygen dose to maintain a desired blood oxygen saturation level is disclosed. The system and method are particularly suited for use with ambulatory patients having chronic obstructive lung disease or other patients requiring oxygenation or ventilation. In one embodiment, the method includes delivering a first oxygen dose to the patient while repeatedly sequencing through available sequential oxygen doses at predetermined time intervals until the current blood oxygen saturation level of the patient attains the desired blood oxygen saturation level. The method then continues with delivering the selected oxygen dose to the patient so as to maintain the desired blood oxygen saturation level. |
