ReviewTracheal gas insufflation as an adjunct to mechanical ventilation.
Tracheal gas insufflation (TGI) as an adjunct to mechanical ventilation delivers fresh gas into the central airways continuously or in a phasic fashion to improve the efficiency of alveolar ventilation or to minimize the ventilatory pressure requirements. Recently, TGI has received increasing attention as an adjunctive tool for lung-protective mechanical-ventilation strategies. ⋯ Experimental studies in animal models of lung injury have substantiated the potential role of TGI in clinical practice. Currently, the evolution of TGI is entering a phase in which overcoming obstacles to clinical implementation may lead to the development of commercial systems with more widespread TGI application.
