Spontaneous Breathing Trials: How Does Your Shop Handle This?

There has been quite a bit of variation regarding pressure support trials, spontaneous breathing trials, liberation trials, whatever you want to call it.
I recently looked at the data for my academic curiosity and would like your input as to how you do it at your shop. I’d like to apologize in advance if I don’t write back to each of you in a timely fashion. I’ll try my best.

Here’s how I like to approach it (in the ideal world).
1. Patient isn’t deteriorating and they’ve done well on their spontaneous awakening trial (SAT).
2. RT goes ahead and places them on pressure support (PS or PSV are the lingo)
3. PS for 30 minutes and the RT flips them back into their prior setting on the vent if they don’t fly.
4. If they do fly, I eyeball the patient and have my RT teammate pull the tube.

I usually have HFNC or NIPPV at the bedside in case they have a high likelihood of needing reintubation.

I know many clinicians check ABGs prior to extubating their patients. I very rarely do. I think I’ve checked maybe 2 or 3 prior to extubating in the almost 2.5 years that I’ve been out of training.

A 🎩 tip to the authors.

Let’s reduce the mechanical ventilation days with this! 💪🏼
