1. A device for determining a respiratory effort of a subject, the device comprising:
a receiver configured to receive a posture signal indicating at least one position of the subject, a breathing signal indicating breathing cycles of the subject, and an electromyography signal indicating neuronal activity of the subject, wherein the electromyography signal is measured independently of the posture signal and the breathing signal; and
a processor configured to determine the electromyography signal for determining the respiratory effort of the subject that is received based on only when the received posture signal indicates a predetermined semi-recumbent position within a range from approximately 40 to 60 degrees relative to an axis vertical to the ground or a sitting position of the at least one position of the subject and the received breathing signal indicates a predetermined point/interval of an inhalation stage of the breathing cycles cycle of the subject, wherein the predetermined semi-recumbent position or sitting position and the predetermined point/interval of the inhalation stage are based on repeated daily measurements,
wherein the processor is further configured to derive the respiratory effort from at least one of an analysis or an interpretation of the determined electromyography signal; and
an indicator, wherein the indicator is configured to indicate the posture signal of the subject by indicating the at least one position of the subject relative to the axis vertical to the ground, and further configured to provide an alarm if the position of the subject does not fall within the predetermined semi-recumbent position within the range from approximately 40 to 60 degrees relative to the axis vertical to the ground or the sitting position and/or if the respiratory effort is not within a predetermined range.
