A new method for enhanced expectoration of sputum by vibratory stimulation of the cervical trachea

Conclusions The tracheal vibration method may be effective at removing central airway sputum and does not require repeated forced expiratory effort, which can otherwise cause exhaustion in patients with decreased lung function. Further investigation is required to confirm its use as a new oscillation technique.
