Key result
Spontaneous oscillations of the radial artery diameter (period 45-70 s, amplitude 80 +/- 14 microns) were observed in healthy males, causing a 1.5- to 2-fold change in arterial distensibility.

Oscillations may confound radial artery assessments in practice; leaves open prevalence and mechanisms in disease.
Observational (n=6)
The radial artery exhibits spontaneous low-frequency diameter oscillations that significantly affect arterial distensibility, likely mediated by an intrinsic vascular mechanism.
Hayoz et al. (1993) conducted an observational in Healthy volunteers (n=6). Spontaneous oscillations of the radial artery diameter (period 45-70 s, amplitude 80 +/- 14 microns) were observed in healthy males, causing a 1.5- to 2-fold change in arterial distensibility.
