METHOD FOR RESPIRATORY MEASUREMENT
First Claim
1. A method for measuring respiration using impedance pneumography over a duration of at least several minutes, several hours or over the duration of night sleep, the method comprising:
- using at least one electrode configured to be in contact with an arm of a human body and at least one electrode configured to be in skin contact with the thorax of the human body;
defining impedance signal changes which relate to the respiratory volume changes or time-differentiated impedance signal changes which relate to the respiratory flow; and
analyzing variation over time in flow-time, volume-time, flow-volume curves, or derived numerical indices, or plain respiratory impedance signal or its time derivate over the duration of at least several minutes, several hours or over the duration of night sleep.
