Abstract
The invention relates to a device for analyzing a patient's respiratory status, including: means for determining electromyographic activity (EMG-AN) at the wings of the patient's nose and the start of nasal contractions; means for determining electromyographic activity (EMG-THO) at the patient's thorax and the start of thoracic inspiratory contractions; means for determining the rostro-caudal delay between the start of the nasal contractions and the start of the thoracic inspiratory contractions; means for comparing the delay to a threshold; and means for supplying an alarm signal when the delay is above said threshold.
