I could have written this myself. We do have trach to vent patients on our floor, but it's exactly as you say. Even down to the physicians "not trusting floor nurses.”We are mostly neuro ICU/MSICU in a level 2 trauma hospital and some days we don't have a tech. My back is in rough shape. I think the issue is our hospital doesn't have a "step-down" floor.
The Intensivists are great in that they get people off drips and vents sooner, but that means patients aren't staying ICU for long... thus they upgrade, and stay on our unit forever.
After 7 years as a nurse and 4 as a tech prior, I'm leaving the bedside next year. I think we have a universal experience (at least it's common enough). Some shifts it's not so bad, others it's awful and I'm personally jumping off this train.
You can try another ICU that's possibly in the city or trauma one. Or you can try your hand in CVICU, it's a different patient population.
