Aortic pressure tracing vs femoral arterial pressure tracing

Aortic pressure tracing vs femoral arterial pressure tracing

Upstroke and downstroke are sharper in a peripheral arterial pressure tracing compared to the central aortic pressure tracing. Amplitude is higher in a peripheral tracing due to amplification of the pressure wave. The dicrotic notch in the peripheral arterial tracing will be lower compared the incisura of the aortic pressure tracing. The differences are due to the higher resistance in the periphery and the presence of the reflected wave.
