1. Apparatus comprising:

  • a non-contact motion sensor configured to sense motion of a patient and to generate a motion signal in response thereto;

    an output unit; and

    a control unit configured to;

    derive, from the motion signal, a respiration rate of the patient, respiration motion signal amplitude of the patient, and changes in posture of the patient, by analyzing the motion signal,identify breathing of the patient as being rapid shallow breathing, in response to;

    detecting both of (a) an increase in the respiration rate, and (b) a decrease in the respiration motion signal amplitude, andonly in response to further detecting that an onset of (a) and (b) is not temporally associated with a change in a posture of the patient compared to before detecting (a) and (b), anddrive the output unit to generate an alert in response to identifying the breathing of the patient as being rapid shallow breathing.
