Abstract:
1. A device for analyzing a patient's respiratory state, comprising: a first analog-to-digital converter to convert a signal representative of electromyographic activity (EMG-AN) at a level of alae of a patient's nose and a beginning of nasal contractions to provide a first digitized signal; a second analog-to-digital converter to convert a signal representative of electromyographic activity (EMG-THO) at a level of the patient's thorax and a beginning of thoracic inspiratory contractions to provide a second digitized signal; and a processor, operatively connected to the first and second analog-to-digital converters, operative to: determine rostro-caudal delay between the beginnings of the nasal contractions of the first digitized signal and of the thoracic inspiratory contractions of the second digitized signal; compare said delay with a threshold; and generate an alarm signal when said delay is greater than said threshold.
