From: Mean arterial pressure differences between cuff oscillometric and invasive blood pressure
Relationship between the difference in cuff oscillometric mean arterial pressure and invasive mean arterial pressure (x-axis both plots) and the difference in cuff and invasive systolic blood pressure (systolic BP; y-axis top plot) or the difference in cuff and invasive diastolic BP (y-axis bottom plot) recorded from five different automated cuff oscillometric BP devices (including one device with measurement on inflate and measurement on deflate capacity) compared with invasive aortic BP. Each of the six different devices/measurement modalities is represented with a different colour for the individual data points and trend lines. All differences were calculated as cuff minus invasive aortic BP. The Welch Allyn non-invasive BP module was within the PulseCor R7 device which is no longer available. The PAR UP non-invasive BP module was within the Uscom BP+ and the version of the device used in this study has now been superseded and is no longer available
