Mean Arterial Pressure

To determine the value of the mean arterial pressure it is necessary to acquire the pressure values at the brachial artery level, using a traditional validated sphygmomanometer.

The WPulsePen software allows the user to choose the way to calculate the mean arterial pressure.
Mean Arterial Pressure = Diastolic Blood Pressure + Pulse Pressure * x; where Pulse Pressure is Systolic Blood Pressure minus Diastolic Blood Pressure.
The operator can choose one of the following options:

../Figure: 33

1)    Apply always the value of 0,33 to 'x' that is:
       Mean Arterial Pressure = Diastolic Blood Pressure + Pulse Pressure / 3;
       i.e. Mean Arterial Pressure is Diastolic Blood Pressure + 33% of Pulse Pressure.

2)   Apply always the value of 0,4 to 'x' that is:
      Mean Arterial Pressure = Diastolic Blood Pressure + Pulse Pressure / 2.5;
       i.e. Mean Arterial Pressure is Diastolic Blood Pressure + 40% of Pulse Pressure.

3)   Calculate the value of x based on the pressure curve recorded in Brachial Artery with tonometry: the latter option is the one that comes closest to the real situation.

After changing the method of calculating the mean arterial pressure, you need to confirm the change (button in the upper right corner).
