Central pulse wave profile. The central pulse wave profile can be broken into the following parameters: diastolic blood pressure (DBP), first peak of pressure (P1), time of return of the reflected wave (Tr), second peak of pressure (P2), systolic blood pressure (SBP), and pulse pressure (PP). Augmented pressure (AP), reflecting the amount of central pressure increase that is due to the earlier arrival of reflected wave, can be calculated by subtracting P2 from P1.
