AbstractLung volume recruitment can improve peak cough flows and respiratory compliance in patients who either do or do not require mechanical ventilation. There are several lung volume recruitment techniques: air stacking, glossopharyngeal breathing and mechanical insufflation-exsufflation with cough assist devices. The principle of lung volume recruitment is based on the insufflation of air in the lungs after maximal inspiration. In air stacking, a manual resuscitation bag is used for insufflation. Glossopharyngeal breathing requires the use of oropharyngeal and laryngeal muscles by the patient. The mechanical cough assist device exsufflates the air after insufflation. These techniques may prevent pulmonary complications, hospital admission and tracheotomy in patients with a reduced ability to cough, a proclivity towards atelectasis and recurrent airway infections. The combination of long-term mechanical ventilation with lung volume recruitment has led to further improvement in the prognosis of chronic respiratory failure. More patients may potentially benefit from lung volume recruitment than only those being converted from short-term to long-term mechanical ventilation.
