Latest Patents

One of Macklem's latest patents is titled "Phonospirometry for non-invasive monitoring of respiration." This invention addresses the challenge of poor signal-to-noise ratios when transforming a patient's tracheal sound signal into a respiration flow signal. The method utilizes transformed signals when the sound signal exceeds a certain threshold, while interpolated values are employed when it falls below that threshold. This approach ensures a reliable volume of breath signal is obtained. Additionally, the device can detect respiration start and stop by analyzing the sound signal or through physical measurements of the patient. A wearable device incorporating this sound signal processing method can provide immediate alerts when the volume of breath signal indicates a medical condition requiring attention.

Another significant patent by Macklem involves the "Measurement of airway calibre." This invention determines the variation in flow resistance of the respiratory system (Rrs) as an indicator of changes in airway calibre. By oscillating the system at a frequency of 6 Hz for 5-15 minutes, variations in the pressure difference (Prs) across the system that is in phase with flow are measured. This variation can serve as a prognostic indicator for asthmatics and can also be used to evaluate the efficacy of treatments.
