#### Mean Values

In the table, the mean values of all the assessed hemodynamic parameters are shown related to the carotid pulse wave analysis.
Blood pressure and heart rate variation monitoring:
The below table shows the variation for heart rate (HR) and Brachial Systolic blood pressure (bSBP) at peripheral determination time (FEM, Femoral Artery; RAD, Radial Artery, and so on), compared to the central determination time (CAR, Carotid Artery). When the pulse wave velocity (PWV) determination is carried out in two steps (ECG + Tonometer mode), significant variation in heart rate or systolic blood pressure between the recording of the proximal and distal pulse waveforms may occur.
Excessive changes in heart rate and systolic pressure are shown in the table with a red background for the involved percentage change (see also the "PWV Reliability" paragraph).
In the above example the systolic blood pressure at Brachial Artery level (bSBP) during the Femoral Artery assessment was 168 mmHg and during the Carotid Artery assessment was 167 mmHg, with a variation of less than 1%.
The diastolic blood pressure at Brachial Artery level (bDBP) during the Femoral Artery assessment was 84 mmHg and during the Carotid Artery assessment was 80 mmHg with a variation of 4 mmHg (5%).
Heart rate (HR) during the Femoral Artery assessment was 69 bpm and during the Carotid Artery assessment was 63 bpm with a variation of 6 bpm (10%).
How to change peripheral blood pressure values, distances and investigated Artery:
WPulsePen software allows changing the blood pressure values previously inserted during the measurement.
Click with the mouse in the field highlighted in the figure below
If the examination refers to a Carotid Artery, it is possible to modify:
- Brachial systolic blood pressure [bSBP]
- Brachial diastolic blood pressure [bDBP]
If the examination refers to a peripheral Artery, it is possible to modify:
- Brachial systolic blood pressure [bSBP]
- Brachial diastolic blood pressure [bDBP]
- Carotid-to-peripheral Artery (Femoral, Radial, etc.) distance [CAR-PER]
- Carotid-to-Suprasternal notch distance [CAR-sSN]
- Suprasternal notch-to-peripheral Artery (Femoral, Radial, etc.) distance [sSN-PER]
You can change also the artery.
Place the mouse pointer in the field corresponding to the artery by selecting it with the left mouse button
After changes are done, you need to confirm pressing "OK".
