SYSTEM AND METHOD FOR RESPIRATORY EVENT DETECTION

PROBLEM TO BE SOLVED: To provide improved systems and methods for processing data from inductive plethysmographic recordings of cardio-respiratory parameters.SOLUTION: The invention is directed to improved systems and methods for processing respiratory signals derived generally from respiratory plethysmography, and especially from respiratory inductive plethysmographic sensors mounted on a garment for ambulatory recording. The systems and methods provide improved signal filtering for artifact rejection, improved calibration of sensor data to produce outputs indicative of lung volumes. Further, the invention provides improved systems and methods directed to processing lung volume signals, however measured or derived, to provide improved determination of respiratory parameters and improved recognition of selected respiratory events. The invention also provides systems and methods for detection of intermittent physiological events, such as coughs and sighs, that are enabled by the improved processing.
