A second parameter representing the percentage of cycles initiated by the patient over the day, for example, during the second observation window, a third parameter representing the device usage time, for example, during the third observation window, for example Means for collecting and processing parameters representing a large change in one of said parameters over at least two consecutive or non-consecutive days within n consecutive days N is strictly greater than 3, preferably ≧ 5, and accordingly said patient to inform the patient of a large risk of worsening cardiopulmonary status Addressed were (or addressed to a third party of the clinician, etc.) and generates an alarm, a method and apparatus.
