Abstract

Purpose

The spontaneous breathing trial (SBT)—relying on objective criteria assessed by the clinician—is the major diagnostic tool to determine if patients can be successfully extubated. However, little is known regarding the patient’s subjective perception of autonomous breathing.

Methods

We performed a prospective observational study in 211 mechanically ventilated adult patients successfully completing a SBT. Patients were randomly assigned to be interviewed during this trial regarding their prediction of extubation success. We compared post-extubation outcomes in three patient groups: patients confident (confidents; n = 115) or not (non-confidents; n = 38) of their extubation success and patients not subjected to interview (control group; n = 58).
