I was called into a non vented trach patients room by another nurse on the floor....neither of us knew the patient except his pulse ox was 83%. His cuffed trach was lying on his chest. It was covered with mucous and blood and still inflated . I grabbed the first clean trach I could find and placed in back in the stoma. The patient recovered sats after that. So problem is that the one I reinserted was a size bigger than the one he had prior. I had no idea what size he had..the primary nurse was hanging blood down the hall and didnt know whay was going on, happened so fast. His trach size had just been downsized that day. Now the Doctor is very mad. He wanted my name etc... Im pretty sure I did the right thing. Thoughts? How do I handle this so I dont get in trouble. Thanks
