The same procedure was performed, only using a camera from the cell phone – for the experiment was used the iPhone 4 – to photograph the finger and see the color variations. These photos were taken using the application developed for this purpose.

These findings will collaborate to make cardiac surgeries safer, by gathering more accurate data, by using technological resources rather than human analysis, which often has greater margins of error.
