The Effect of Vascular Occlusion on Pulse Flow

Effect of Proximal Cuff

graded proximal cuff occlusion

Graded acute changes in forearm PPV was found to accompany the decrease in limb flow caused by a graded proximal cuff occlusion. Compared to baseline, inflations at diastolic pressure resulted in an 11.4% increase in PPV (p<0.01). Supra-diastolic cuff inflations resulted in a linear decrease in PPV (r=0.99, p<0.01).
