Summary of collateral dependent blood flow measurements made using manual and automated inflation protocols for before and after transient repetitive myocardia ischemia (RI).

Automated inflation produced a marked decrease in the standard error of the mean (SEM) and coefficient of variation (CV), even with reduced sample numbers (n). Data were tabulated from several studies for this comparison: WKY manual inflation studies [23], WKY automated inflation studies [25], SD manual inflation studies (unpublished), SD automated inflation studies [26]. *Indicates normal-zone blood flow (not collateral dependent flow) measured at 0 days RI.
