Abstract:Objective To observe application effect of the high frequency of the chest wall vibration
expectoration drainage system in some patients with mechanical ventilation. Methods 30 cases of
discharge blocking the airway nursing patients with mechanical ventilation were taken care by the high
frequency of the chest wall vibration expectoration drainage system. The relevant data of the maximum
velocity and sputum properties of the expiration before and after, and the sputum properties were
separately collected. Statistical analysis was performed on these data. Results The maximum velocity of
the 30 patients’ expiratory was improved significantly after using the chest wall vibration expectoration
drainage system. It was easier for the patients to discharge sputum. The scores of both exhale maximum
velocity and sputum properties for the post-test were higher than those for the pre-test and the difference
had statistical significance (P<0.01). Conclusion High-frequency chest wall vibration expectoration
drainage system can effectively remove the peripheral airway mucus of the mechanical ventilation
patients. It can reduce airway resistance and improve ventilation obstruction.
