Guidelines for T-Piece Use in Tracheostomy Patients at Night

Tracheostomy Tube Selection for Nocturnal Use

The American Thoracic Society recommends cuffed tracheostomy tubes for patients requiring nocturnal ventilation, with the cuff inflated at night and deflated during the day to allow speech and breathing around the tube 1, 2
Cuffed tracheostomy tubes should maintain cuff pressures below 20 cm H2O to preserve airway epithelium perfusion and prevent tracheal injury, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 2, 3
For patients with high-pressure ventilation needs, the American Thoracic Society recommends using low-pressure/high-volume cuffs rather than low-volume/high-pressure cuffs to minimize tracheal wall damage 2

The American College of Chest Physicians recommends using a T-piece with an expiratory filter for spontaneously breathing tracheostomy patients to reduce environmental aerosol dispersion 4
The American Academy of Otolaryngology-Head and Neck Surgery suggests using a heat moisture exchanger (HME) with viral filter when disconnecting from closed-circuit systems to minimize aerosolization 3

The American Academy of Otolaryngology-Head and Neck Surgery recommends maintaining cuff pressure between 20-30 cmH2O for air-filled cuffs to prevent tracheal injury while maintaining circuit integrity 3
The American Academy of Otolaryngology-Head and Neck Surgery advises against hyperinflation of cuffs as this increases risk of tracheal injury 3

The American Academy of Otolaryngology-Head and Neck Surgery recommends using closed-circuit suctioning systems with inline suction catheters to decrease aerosolization risk 5
The Centers for Disease Control and Prevention suggest using only sterile fluid to remove secretions from suction catheters if they will be re-entered into the patient's respiratory tract 6

The American Academy of Otolaryngology-Head and Neck Surgery strongly prefers heat moisture exchangers (HMEs) over large-volume humidifiers to prevent airway dryness and secretion thickening 3

The Centers for Disease Control and Prevention recommend decontaminating hands before and after contact with the tracheostomy tube or any respiratory device 6
The Centers for Disease Control and Prevention advise wearing gloves when handling respiratory secretions or objects contaminated with respiratory secretions 6

The American Academy of Otolaryngology-Head and Neck Surgery prefers pressure support mode with an inflated cuff over spontaneous breathing trials using T-piece to avoid aerosol generation during weaning 3
The American Academy of Otolaryngology-Head and Neck Surgery suggests considering one-way speaking valves or capping once the patient tolerates cuff deflation or a cuffless tracheostomy tube to facilitate speech and promote weaning 3
