Abstract
An automated sphygmomanometer in which the timeout duration of respective deflation periods during which oscillatory complexes may be detected is alternated so that the monitor cannot synchronize with the heart rate for more than one deflation step. The timeout durations at each deflation step are alternated to have long-short-long-short durations so that the overall duration of the measurement cycle is preferably about the same as in conventional monitors in which the timeout periods all have the same duration. Once the oscillatory complexes are detected, the timeout is typically not needed and the processing proceeds to the next deflation step in a conventional manner.
