MAP (Mean Arterial Pressure)
The device measures the true mean arterial pressure (MAP) of the patient. Each
measurement includes a single MAP value. The MAP value will always be displayed
together with the systolic and diastolic blood pressure value.

Accuracy of the central blood pressure parameters
The accuracy of central blood pressure parameters performed with this device can only
reliably be determined against intra-arterial blood pressure measurement. The device is
a certified equivalence with the WatchBP Office Central that has been validated against
simultaneous recorded intra-arterial blood pressure measurement in 85 subjects and
showed high accuracy

.
The time that is needed to determine the central blood pressure value may vary among
patients; i.e. with faster heart rate, less time is required for collecting the number of
required PVP waveforms. It is very important to keep the arm still during the time the
PVP waveforms are collected.
