High-frequency jet ventilation is a novel technique for providing mechanical ventilation in the out of operating room (OOR) setting. Case reports and a small series of patients have shown it to be useful in patients undergoing cardiac arrhythmia ablations, interventional radiology procedures, and extracorporeal shock wave lithotripsy. Recently, interest in the technique has grown tremendously as the ability to provide superior surgical conditions may lead to improved efficiency and less side-effects in a variety of procedures.
Atrial fibrillation ablation procedures, liver tumor ablations, and extracorporeal shock wave lithotripsy are all the procedures that benefit from minimal movement of the heart, liver, and kidney, respectively, during the procedure. Although randomized controlled trials are lacking, increasing data suggest that by maintaining the thoracic and abdominal structures relatively immobile throughout the respiratory cycle, the efficiency and safety of these procedures may be improved.
Technological advances are allowing an increasing number of surgical procedures to be performed in the OOR setting. Such procedures often depend on the precise application of ablation catheters or shock waves. High-frequency jet ventilation facilitates the improved accuracy of catheter and shock wave placement, as well as efficiency of a variety of procedures. Improved efficiency, with fewer side-effects, has tremendous implications for the growth of such procedures in the OOR setting.
高频喷射通气是一种在手术室外环境中提供机械通气的新技术。病例报告和小系列患者研究表明，它在接受心律失常消融、介入放射学程序和体外冲击波碎石术的患者中非常有用。最近，由于提供更好的手术条件的能力可能会在各种程序中提高效率并减少副作用，因此该技术的兴趣大大增加。
房颤消融程序、肝脏肿瘤消融和体外冲击波碎石术分别受益于心、肝和肾在手术过程中最小的运动。尽管缺乏随机对照试验，但越来越多的数据表明，通过在整个呼吸周期中保持胸部和腹部结构相对不动，可以提高这些程序的效率和安全性。
技术进步使得越来越多的手术能够在手术室外环境中进行。这些程序通常依赖于消融导管或冲击波的精确应用。高频喷射通气有助于提高导管和冲击波放置的准确性，以及各种程序的效率。效率的提高和副作用的减少，对这些手术在手术室外环境中的发展具有巨大的影响。
