Patent number: 11850077Abstract: Disclosed is a cardio-pulmonary health monitoring apparatus. The apparatus comprises a contactless motion sensor configured to generate one or more movement signals representing bodily movement of a patient during a monitoring session; a processor; and a memory storing program instructions configured to cause the processor to carry out a method of processing the one or more movement signals. The method comprises extracting one or more sleep disordered breathing features from the one or more movement signals, and predicting whether a clinical event is likely to occur during a predetermined prediction horizon based on the one or more sleep disordered breathing features.Type: GrantFiled: August 21, 2019Date of Patent: December 26, 2023Inventors: Klaus Henry Schindhelm, Steven Paul Farrugia, Michael Waclaw Colefax, Faizan Javed, Rami Khushaba, Conor Heneghan, Philip De Chazal, Alberto Zaffaroni, Niall Fox, Patrick Celka, Emer O'Hare, Stephen James Redmond

Publication number: 20220265944Abstract: A controller or processor(s) implements detection of respiratory related conditions, such as asynchrony, associated with use of a respiratory treatment apparatus or ventilator. Based on data derived from sensor signals associated with the respiratory treatment, the detector may evaluate a feature set of detection values to determine whether or not an asynchrony occurs in a breath of the patient's respiratory cycle such as by comparing the values against a set of thresholds. Different events may also be identified based on the particular feature set and threshold(s) involved in the detection processing. Automated determination of feature sets may also be implemented to design different asynchrony event classifiers. The methodologies may be implemented by computers or by respiratory treatment apparatus.Type: ApplicationFiled: March 15, 2022Publication date: August 25, 2022Inventors: Qestra Camille MULQUEENY, Stephen James REDMOND, Nigel Hamilton LOVELL

Patent number: 11337645Abstract: A sleep monitoring system includes an ECG device (2) and a respiration inductance plethysmogram (3) which monitor cardiac activity and physical (ribcage) respiration respectively and feed representative signals to a digital data processor. Operations (5-9) process the beat interval data, while in a second thread, operations (20-24) independently process the amplitude modulation of the ECG data caused by the respiratory motion of the subject. The inductance plethysmogram device (3) provides an input to the processor which represents respiration as directly monitored independently of the ECG. Operations (30-34) process this direct respiration data independently and in parallel, in a third thread. All extracted features are fed to a classifier which in step (10) combines selected combinations of features to make decisions in real time.Type: GrantFiled: June 19, 2019Date of Patent: May 24, 2022Inventors: Conor Heneghan, Stephen James Redmond
