Method and system for respiratory phase classification using explicit labeling with label verification |
摘要 |
A method and system classify respiratory phases in a single channel acoustic signal as inspiratory and expiratory using explicit labeling with label verification. In the method and system, a subject explicitly indicates through a user input the start of a respiratory cycle (i.e. start of inspiration). The phase indication is applied to provisionally label several consecutive phases of a single channel acoustic signal as inspiratory and expiratory. A provisional phase rule set is then generated based on characteristic differences between the inspiratory and expiratory phases. The phase indication, provisional labeling and provisional rule set generation steps are then repeated. The two generated provisional rule sets are then compared for a match to verify the accuracy of the subject's phase indications and the ability to automatically recover phase in the event of signal loss.
