Abstract
The invention relates to a method and apparatus for determining a respiration of a subject () in which, with a single multi-axial accelerometer () positioned on a body of the subject (), accelerometer signals are generated () indicative of the acceleration of the subject () along different spatial axes, a vector magnitude signal of the acceleration of the subject () along the different spatial axes is calculated () from the accelerometer signals, a non-respiratory motion contribution to the acceleration along the different spatial axes is identified () from the vector magnitude signal, which non-respiratory motion contribution is not caused by the respiration, and a respiration signal indicative of the respiration of the subject is determined () by filtering the non-respiratory motion contribution from at least one of the accelerometer signals. In this way a method is provided which determines the respiration of a subject () with a single accelerometer () in an efficient and, for a patient, comfortable way.
