Hi!!! I work at an ER :3 It's a small one to be exact so I don't see a lot of trauma. Hmmmm lemme see, I was putting in a IV on a patient and they started saying- "I can't see anything.", "My fingers and toes are tingling." I was like- "Uh oh." They ended up passing out on me for a good minute. I was scared :X luckily I put it in place and got her into an actual room. It isn't that crazy but it definitely was a first :p
