1. A method of treating an obstructive airway disorder in a patient who has been diagnosed with an obstructive airway disorder comprising the step of:

  • monitoring an indication of respiratory activity from tissue internally within the patient via at least one electrode;

    detecting via a processor for a characteristic indicative of an obstructive respiratory event from the respiratory activity; and

    ,upon detection of the characteristic providing electrical stimulation to the diaphragm or phrenic nerve tissue at least to an end of exhalation where a waveform of the stimulating signal for controlling exhalation is adjusted in response to the sensed parameter whereby a supplemental lung volume is preserved to thereby mitigate an obstructive disorder.
