Sonometric assessment of cough predicts extubation failure: SonoWean—a proof-of-concept study
Authors' conclusion
Sonometric assessment of cough strength might be helpful to identify patients at risk of extubation failure in patients undergoing IMV.
Study context
- Population
- Patients under invasive mechanical ventilation (IMV) >24 h completing a successful spontaneous T-tube SBT1-year period
- Participants
- 106 participants
- Comparison
- Sonoscore in extubation failure vs success
- Extubation failuren = 15
- Outcome
- Extubation failure prediction by Sonoscore (mean of 3-cough volume in decibels, sonometer, end of SBT)
Methodological detailsproof-of-concept
- Proof-of-concept
