Patient complains of pain with ambulation in his calf. He says its so bad that he has to stop walking for about 5 min until he can begin walking again. He normally can walk about 75 yards before he must stop. If you were to guess his ABI level what would you guess?
I would guess about .6. The range for intermitant claudication is .5 - .8. Less than .5 is associated with rest pain. And above 1 is calcified vessels.
