Get with the program, the solution is right in front of your faces. Simply color code the tubes available for purpose. For instance red lines for blood, yellow lines for air and green lines for food. Color coding is used exstensively in hospital settings already for a wide variety of uses and this would mean that it would be far more difficult to mistake tubes. The stripes should be along the tubes, like straws for beverages, and should not make the tubes opaque but help the nurses differentiate purpose. And these new tubes would not need a major revamp of the manufacturing process either as the stripes could be added on the outside and not change the major properties of the tubing.

When is the congress going to stop lying to the people, this time it is a glitch that is blamed? There is no glitch, the people in power know what is wrong. The US has too much debt and you know why? Because the people in the US bully the politicians into spending all the money they have and someone in charge needs to be introduced to tough love. Give the people what they need not what they want, that is true power and will solve our money problems.
