Palpation of the pulses in the peripheral vascular examination is typically to assess amplitude or strength. Pulse amplitude is graded on a 0 to 4+ scale, with 4+ being the strongest. Elasticity of the artery wall may also be noted during the peripheral vascular examination, by palpating for a resilient (bouncy) quality rather than a more rigid arterial tone, whereas pulse rate and rhythm are best assessed during examination of the heart and neck vessels.
