Abstract: A method and system for monitoring respiratory function that includes an impedance sensor configured to sense a first thoracic impedance waveform for at least one breath of a patient, a memory configured to store a first threshold slope value, and a processor configured to determine an first breath slope value in response to the impedance waveform, compare the first breath slope value to a first threshold slope value, and determine an indication of respiratory function of the patient in response to the comparing.
