The occlusive pressure achieved with BFR depends on cuff width, with leg cuffs requiring higher pressure (e.g., 158 mmHg) than arm cuffs (e.g., 94 mmHg).

“it's interesting to note the pressure of occlusion is much higher than systolic pressure because it's it's a function of how wide the band is so i noticed today when i did my legs the occlusive pressure was 158 millimeters of mercury well that's way above my systolic pressure my systolic blood pressure is very low i tend to run super low in blood pressure as evidenced by the fact that i face planted in brazil last month um and my upper body occlusive pressure with those cuffs is about 58 millimeters of mercury so you have one that's like oh sorry 94 millimeters of mercury tends to be approximately occlusive on upper body 154 or something 158 on the lower body but again it's also a function of the width of the cuff so that's why i realize you can't just just knowing your blood pressure isn't enough to do this”
