摘要：
A respiration rate sensor comprises an attachable sensor module 12, attachable to a casualty's face, the module having a respiratory sensing region 48 comprising an air temperature sensor and a humidity sensor (56, figure 4) arranged such that, when the module is attached, airflow 54 in and out of the casualty's lungs flows over the respiratory sensing region. A signal processing system, coupled to the sensor module, processes and combines signals from the temperature and humidity sensors to determine a respiration rate for said casualty. The device can further include an optical heart rate sensor to determine heart rate. In preferred embodiments the sensor is arranged to clip to a casualtys nose or mouth via hinged jaws 12a, 12b, which can be resiliently biased together by a plastic spring.
