Abstract
An apparatus may include a sensing circuit and a processor. The sensing circuit is configured to generate a sensed physiological signal, wherein the physiological signal includes respiration information of a subject. The processor includes an end expiratory volume (EEV) module configured to determine a value of EEV of the subject using the sensed physiological signal, and a lung hyperinflation detection module configured to generate an indication of lung hyperinflation of the subject according to the value of EEV and provide the indication to at least one of a user or process.
