Abstract:
1. A method for determining cuff slippage in a blood pressure monitoring device, the method comprising: on the blood pressure monitoring device, starting a cuff inflation including inflating a blood pressure cuff; obtaining a plurality of pressure samples when the blood pressure cuff is inflating; determining, by a processing device, whether a slope corresponding to the plurality of pressure samples is a positive number; when it is determined that the slope is a positive number, determining the processing device, a level of background noise during the blood pressure cuff inflation, the level of background noise being determined from the plurality of pressure samples; and when the background noise is determined, determining, by the processing device, from the plurality of pressure samples whether a pressure pattern indicating cuff slippage is obtained; wherein determining from the plurality of pressure samples whether a pressure sample pattern indicating cuff slippage is obtained comprises:
