Newer ventilatory strategies.
Over the past year a large number of innovations in mechanical ventilation have been evaluated. Three of the most exciting are non-invasive positive pressure ventilation, tracheal gas insufflation and partial liquid ventilation. Non-invasive positive pressure ventilation is now clearly a standard of care in the management of an acute exacerbation of chronic obstructive pulmonary disease. In addition, its use in other clinical settings is being actively explored. Tracheal gas insufflation appears to be a useful adjunct to mechanical ventilation for the management of carbon dioxide but requires manufacturer-designed devices for safe application. The effects of partial liquid ventilation on lung injury have been more clearly defined in the past year as well as approaches to provide gas ventilation during partial liquid ventilation.
