Equipment review: Tracheal gas insufflation
47cc-2-2-043 Introduction Tracheal gas insufflation (TGI) is an adjunctive ventilatory technique that delivers fresh gas into the trachea either continuosly or only during a specific segment of the respiratory cycle (phasic flow) [1-4]. Two mechanisms are responsible for improving the efficacy of conventional tidal breaths during TGI [5-7]. First, fresh gas introduced by the catheter during exp...
متن کاملMonitoring and humidification during tracheal gas insufflation.
In order to use tracheal gas insufflation (TGI) in a safe and effective manner, it is important to understand potential interactions between TGI and the mechanical ventilator that may impact upon gas delivery and carbon dioxide (CO2) elimination. Furthermore, potentially serious complications secondary to insufflation of cool, dry gas directly into the airway and the possibility of tube occlusi...
متن کاملTracheal gas insufflation and related techniques to introduce gas flow into the trachea.
Over the past 50 years, a variety of techniques have been developed that have in common the insufflation of gas into the central airway to facilitate carbon dioxide (CO2) clearance. These include continuous insufflation of oxygen, transtracheal jet ventilation, high frequency jet ventilation, transtracheal oxygen administration, intratracheal pulmonary ventilation, and tracheal gas insufflation...
متن کاملDistal projection of insufflated gas during tracheal gas insufflation.
Tracheal gas insufflation (TGI) flushes expired gas from the ventilator circuitry and central airways, augmenting CO2 clearance. Whereas a significant portion of this washout effect may occur distal to the injection orifice, the penetration and mixing behavior of TGI gas has not been studied experimentally. We examined the behavior of 100% oxygen TGI injected at set flow rates of 1-20 l/min int...
متن کاملDiagnosis of tracheal injury in mechanically ventilated premature infants by flexible bronchoscopy. A pilot study.
Flexible bronchoscopy (FB) is uniquely suited for the study of large airway lesions in the ventilated premature infant. However, no standardized clinical scoring system of distal tracheal injury exists and the adverse consequences of FB in ventilated premature infants are not well described. Using a prototype Olympus fiberoptic ultrathin bronchoscope with a directable tip and an outer diameter ...
