Method for Determining Respiratory Timing Parameters from Respiratory Monitoring Measurements
Summary
The USPTO granted Patent US12605088B2 to Onera Technologies B.V. on April 21, 2026, covering a method for deriving respiratory timing parameters from respiratory monitoring measurements. The patent discloses a computational method involving respiratory effort and flow signal analysis to identify and refine inspiratory onset times using derivative analysis within peak-to-peak intervals. The patent contains 20 claims and names Alessandro Rossi and Hartmut Schneider as inventors.
What changed
The USPTO issued Patent US12605088B2 to Onera Technologies B.V., covering a method for determining respiratory timing parameters from respiratory monitoring measurements of a subject. The method involves processing respiratory effort and flow signals to identify preliminary inspiratory onset times and then refining those times through derivative analysis within peak-to-peak intervals. The patent includes 20 claims covering the computational approach to respiratory signal analysis.
Medical device manufacturers developing products in the sleep diagnostics, respiratory monitoring, or ventilation sectors should review whether their technologies overlap with the claimed method. While patent grants do not create compliance obligations, companies developing similar respiratory analysis algorithms may wish to consider patent clearance for new product development.

Abstract
The present disclosure relates to a method (MO) for providing respiratory timing parameters from respiratory monitoring measurements of a subject, the method comprising the steps of: providing (M1) a respiratory effort signal (E) and a respiratory flow signal (F) of a subject; determining (M2a) an ensemble of peaks (pE) in the respiratory effort signal (E) and determining (M2b) an ensemble of valleys (vE) in the respiratory effort signal (E); and identifying (M3) times associated with the valleys (vE) as preliminary inspiratory onset times (t′io); refining (M4) preliminary inspiratory onset times (t′io) within respective peak-to-peak time intervals (Tpp) of the respiratory effort signal (E) by: determining (M41) first derivative (F1d) of the respiratory flow signal (F) in a respective peak-to-peak interval (Tpp); determining (M42) local peaks (pF1d) and valleys (vF1d) in the respiratory flow signal first derivative (F1d); determining (M43) a time midpoint (tmid) between the time of a local valley (vF1d) in the respiratory flow signal first derivative (F1d) closest in time to the later endpoint in the respective peak-to-peak time interval (Tpp) and the time of a local peak (pF1d) in the respiratory flow signal derivative (F1d) in the respective peak-to-peak time interval (Tpp); evaluating (M44) whether the respiratory effort signal (E) at the determined time midpoint (tmid) satisfies a predetermined inspiratory onset time condition, and if satisfied, selecting (M45) the determined time midpoint (tmid) as an inspiratory onset time (tio) instead of the preliminary inspiratory onset time (t′io) for that peak-to-peak interval (Tpp), whereas if the condition is not satisfied, keep the preliminary inspiratory onset time as the inspiratory onset time for that peak-to-peak interval.
