Describe a normal arterial pressure waveform.
What will be an ideal response?
The systolic upstroke reflects the rapid increase of arterial pressure in the blood vessel during systole (ventricular contraction). The downslope or dicrotic limb is caused by the declining pressure that occurs during diastole (ventricular relaxation). The dicrotic notch is caused by the closure of the semilunar valves during diastole. The lowest point of the tracing represents the arterial end-diastolic pressure.
