Background: The present study was designed to investigate the evolution and the impact of respiratory muscles function and limb muscles strength on weaning success in prolonged weaning of tracheotomized patients. The primary objective was to determine whether the change in respiratory muscles function and limb muscles strength over the time is or is not associated with weaning success.
Methods: Tracheotomized patients who were ventilator dependent upon admission at a weaning center were eligible.
Article Synopsis
- The study examines how sensory interventions, such as music and air flux stimulation, can help relieve dyspnoea (difficulty breathing) in critically ill patients on mechanical ventilation.
- Researchers found that increasing pressure support on the ventilator significantly reduced dyspnoea, as did auditory stimulation with music compared to pink noise, and facial air flow compared to limb air flow.
- The findings suggest that these sensory interventions could effectively alleviate dyspnoea in ventilated patients without needing medications or increasing ventilator support, which is important for patient care protocols.
Rationale: Dyspnea, a key symptom of acute respiratory failure, is not among the criteria for spontaneous breathing trial (SBT) failure. Here, we sought (1) to determine whether dyspnea is a reliable failure criterion for SBT failure; (2) to quantify the relationship between dyspnea and the respective electromyographic activity of the diaphragm (EMGdi), the parasternal (EMGpa) and the Alae nasi (EMGan).
Methods: Mechanically ventilated patients undergoing an SBT were included.
Background: Patients with ARDS due to COVID-19 may require tracheostomy and transfer to a weaning center. To date, data on the outcome of these patients are scarce. The objectives of this study were to determine the factors associated with time to decannulation and limb-muscle strength recovery.

Our hypothesis was that diaphragm dysfunction is not particularly associated with weaning-induced pulmonary oedema.
Methods: It was a single-centre and physiological study conducted in patients who had failed a first spontaneous breathing trial and who underwent a second trial.
