Folks figuring out how to take their blood pressure at home might be tempted to use online stock photos to see how it's done -- but they really shouldn't, a new study warns.
Only about 1 in 7 stock photos found online correctly depict the right way to measure blood pressure, researchers reported in the journal Hypertension.
"We expected that about 50% of images would be accurate. However, our findings were worse than expected," said lead researcher Alta Schutte, a professor of cardiovascular medicine at the University of New South Wales Sydney in Australia.
"Because people tend to remember images better than words -- a phenomenon known as the picture-superiority effect -- inaccurate visuals could have serious public health consequences," she added in a news release.
