Spontaneous breathing trial

Question 2.

A ventilated patient is nearly ready for SBT, that spontaneous breathing trial.

You want light sedation with an arousable patient who can follow commands.

What best agent to emphasize for this patient? A.

And that's really interesting, right? Because it's saying that in patients you did the T-piece trial on, you were more likely to have extubation failure.

And you start to wonder, is that because you took away the PEEP and everything and that patient got atelectasis and lobar collapse and all that jazz, and then you extubated them and they had more trouble remaining extubated? Then the pressure support trial where you have some inspiratory pressure and some PEEP still there to maintain recruitment, get over that endotracheal tube resistance.

So from this trial, It supported the use of pressure support trials rather than T-piece trials as the most physiologically relevant, patient-friendly SBT method, which is why not many people do T-piece trials anymore.

All right, so going into pressure support trials, since that's kind of the main way in which we try to do spontaneous breathing trials, this is the most common modern approach.
