Abstract
Disclosed embodiments include a method for measuring non-invasive blood pressure from an oscillometric signal and a cuff pressure signal implemented in a medical apparatus comprising: (a) calculating a pulse pressure signal by subtracting an upper and a lower envelope of the oscillometric signal; and (b) calculating without the use of beat detection a mean arterial pressure, a systolic blood pressure, and a diastolic blood pressure from said oscillometric signal, said cuff pressure signal, and a plurality of thresholds a device with at least one processor.
