Abstract:
1. A method for determining a respiration rate of a subject, the method comprising the steps of: measuring a first estimation of the respiration rate in a first way with a first sensor; measuring a second estimation of the respiration rate in a second way with a second sensor, said first sensor and said second sensor sensing a different physical characteristic; setting by means of a control unit one quality value for each of the first and second estimations of the respiration rate; determining a difference by means of the control unit between said first and second estimation of the respiration rate; determining by means of the control unit if said difference is greater or less than 20%; if said difference is less than 20%, then determining by means of the control unit a third estimation of the respiration rate of the subject by use of weighted averaging based on the first and second estimations of the respiration rate and their respective quality values; and if said difference is greater than 20%, then choosing one of the first and second estimations of the respiration rate with the highest quality value as an actual respiration rate of the subject.
