Impact of the Nature and Interface of the Tracheostomy Cannula on Dyspnea in Patients Weaning From Artificial Ventilation in Weaning Unit

"The tracheostomy tube is changed according to the randomization sequence, a filter is connected for 5 minutes; then baseline data will be assessed. The tracheostomy tube is then connected to the four interfaces for 30 minutes each. Parameters is measured after each 30-minute period. The cuff of the tracheostomy tube will be deflated using a syringe when the interface is a filter, phonation valve, or cap. In contrast, the cuff will be inflated when the interface is the ventilator.~The cuff is inflated with a manometer for the low-pressure balloon tracheostomy tube and with the minimum and sufficient amount of injectable water for the plated balloon tracheostomy tube to avoid overpressure"
