The advantages of using MI-E in conjunction with PPV include:
1)MI-E with PPV generates optimal peak cough expiratory flow (PCEF)for clearing airway secretions.
2)MI-E with PPV does not cause airway irritation or discomfort.
3)MI-E with PPV can be used with patients with bullous emphysema.
4)MI-E with PPV may improve vital capacity (VC)and arterial oxygen saturation (SₐO₂)associated with mucous plugging.

Question

The MI-E may be the most effective alternative for generating optimal peak cough expiratory flow (PCEF)and clearing airway secretions.PCEF has increased to as much as 6-10 L/sec during therapy and can be increased more if a manual abdominal thrust can be synchronized with exsufflation.MI-E does not cause the airway irritation and discomfort associated with tracheal suctioning and may actually decrease the production of airway secretions.Abnormal VC values,flows,and arterial oxygen saturation (SₐO₂)values can also significantly improve with clearing of mucous plugs by MI-E.No significant complications have been reported with the use of this device.However,it is contraindicated in patients with bullous emphysema or pulmonary disorders that predispose a patient to barotrauma.
