Claim:
1. A method of assisting the respiratory activity of a patient, comprising: placing a respiratory mask over the mouth and nose of the patient, wherein the respiratory mask comprises a pneumotachograph configured to measure flow rates of inhaled and exhaled air by the patient and to generate from the flow rates at least one respiratory activity signal comprising at least one elementary signal corresponding to a respiratory cycle, the general form of which may be expressed by x(t)=x determining respiratory activity of the patient by performing an analysis of said respiratory activity signal, wherein the analysis of said respiratory activity signal comprises the following steps: wherein r is an anharmonicity parameter measuring the degree of anharmonicity of the signal, the limit r=0 corresponding to a harmonic signal, the limit r=1 to an infinitely anharmonic signal, and k and n are integers; and controlling respiration of the patient based on the respiratory activity of the patient.
