  • Systems and methods for determining respiration information from a photoplethysmograph
    Patent number: 9402554
    Abstract: A signal representing physiological information may include information related to respiration. A patient monitoring system may utilize a wavelet transform to generate a scalogram from the signal. A threshold for the scalogram may be calculated, and scalogram values may be compared to the threshold. One of the scales meeting the threshold may be selected as representing respiration information such as respiration rate. The respiration information may be determined based on the selected scale.
    Type: Grant

    Date of Patent: August 2, 2016
    Assignee: Nellcor Puritan Bennett Ireland
