Vacutainer News Flash

Vacutainers are not actual literal vacuums. There is actual air inside of them.

I may or may not have gotten into a little bit of a tiff with the ICU nurses over this. Per them - vacutainers are a vacuum which contain no air.

Right - because actual vacuums suddenly magically exist on earth. OMG.

For your info. Vacutainers are just blood collection containers. They usually have an additive (ie heparin) to prevent clotting. Air is evacuated from them in order to created negative pressure, which aids in withdrawing blood from very low pressure veins. There are varying "strengths" of vacutainers depending on how much air has been withdrawn.
