A method of monitoring respiratory activity comprises obtaining a respiration sound signal. The respiration sound signal is processed to identify a frequency component corresponding to respiration and an amplitude related parameter of the component is measured. If the measured parameter is in an indeterminate region then a temporal domain related parameter of the component is measured.

Méthode de surveillance de l'activité respiratoire consistant à recueillir un signal sonore de la respiration. Le traitement dudit signal permet d'identifier une composante fréquence correspondant à la respiration et l'on mesure un paramètre en rapport avec l'amplitude de ladite composante. Si le paramètre mesuré se situe dans une région indéterminée, on mesure un paramètre relatif au domaine temporel de la composante.
