Setting and use of a mechanical insufflator–exsufflator in pediatrics
Abstract
The mechanical insufflator-exsufflator (MI-E) is a device that gradually applies positive pressure to the airway, followed by rapid change to negative pressure, facilitating an effective cough. It is especially indicated in subjects who, due to respiratory muscle disorders, are unable to achieve an effective peak cough flow (PCF), which is essential to adequately eliminate secretions. The MI-E can be used through a face mask, oral pipette, or tracheostomy tube. Studies on children with neuromuscular disease have shown that the device is safe and well tolerated, causes an increase in the PCF, decreases the need for respiratory therapy, facilitates extubation, and reduces the frequency of exacerbations or recurrent acute events. The indication and use of the MI-E is increasingly frequent. Therefore, it is essential to know its characteristics, setting, and indications for use in the pediatric population.
