<p>Referring now to figures 1 and 2, a respiratory monitor comprises a detector unit (100) and a base unit (110). The detector unit is mounted on a subject's chest or on clothing lying around a subject's chest such that the detector unit moves in a phase with the respiratory movement of the subject. The detector unit (100) comprises an accelerometer (101), a processor (102), an RF signal generator (103), an RF aerial (104) and a power source (105). The output of the processor (102) is dependent upon the output of the accelerometer (101) and is output to the base unit (110) by the RF (signal) generator.</p> |
