| Wrist blood pressure cuffs can give widely varying readings if improperly used. This video shows how you can "improperly use" a wrist cuff to do a hydrastitic physics experiment that determines the density of mercury. We're talking about a more-than-2-to-1 ratio in blood pressure readings, depending on where the blood pressure cuff is held! It's fun to do armchir physics (literally!) with blood pressure cuffs, but the serious message here is that if you don't use a wrist cuff right, you can ... | Views:898 4ratings |
