What does "no thrill, 2+" in temporal arteries signify?

The phrase "no thrill, 2+" in the context of temporal arteries is indicative of normal blood flow. In clinical assessments, a "thrill" refers to a vibration or a buzzing sensation felt upon palpation, which often suggests turbulent blood flow, potentially due to a blockage or significant narrowing of a blood vessel. The absence of a thrill indicates that the blood flow is smooth and unimpeded, which aligns with normal vascular function.

The "2+" designation typically reflects a graded assessment of pulse amplitude, where 2+ indicates a normal strength of the pulse. This suggests that blood is flowing adequately through the temporal arteries, supporting the assessment of normal hemodynamics and circulation to the area.

In this scenario, signs of increased blood pressure or blockage would typically present a different clinical picture with altered sounds or sensations upon palpation. Decreased circulation would usually be associated with weak or absent pulse presence, rather than a normal amplitude. Thus, the indication of "no thrill, 2+" suggests normal function rather than any abnormalities in blood flow.
