摘要:
A device (1) and a corresponding method are provided for determining and/or monitoring the respiration rate based on measurement with more than one sensor (5, 7, 9, 13, 15). The device may be part of a monitor for determining and/or monitoring the respiration rate. The second and/or additional sensors are different form the first sensor and have a different manor of operation from the first sensor.
