Abstract: A device (100) for monitoring a subject's breathing rate is disclosed. A transducer (107) radiates energy towards the chest of a subject and receives the reflected energy.

The analyzer (105) analyzes the signal to calculate the breathing rate by measuring at least one of a periodicity of the signal and a number of cycles per unit time of the signal. In a preferred embodiment the transducer (107) is disposed in or on a sphygmomanometer cuff to radiate energy towards the chest of the subject and receive the energy reflected by the chest of the subject.

Abstract: Self measurements of physiological parameters such as blood pressure are prone to errors and artifacts since they are often not done according to established and standardized protocols i.e., such that predetermined conditions for a reliable measurement are not met. To determine whether the predetermined conditions for a reliable measurement are met one or more physiological and environmental sensors are used to determine a measurement context. The obtained sensor data is compared with predetermined thresholds to determine whether the context allows a reliable self test. In case the predetermined conditions are not met based on the obtained sensor data instructions are given to guide the subject that wants to do a self test.
