Historically, it has been difficult to provide adequate humidification delivery with the high frequency percussive ventilator (HFPV) used in many burn centers. It is possible burn centers have avoided using HFPV because of the risk of mucus plugging, dried secretions, and cast formation. Experiences with HFPV provided doubt that the HFPV ventilator circuit could supply adequate humidification to patients receiving this mode of ventilation. Independent gas-flow delivery through the ventilator circuit inherent in HFPV provided a challenge in maintaining adequate humidification delivery to the patient. This report describes a dramatic reduction in dried, inspissated secretions by using a novel new humidification device with HFPV. The new device called the Hydrate Omni (Hydrate, Inc., Midlothian, VA) uses a small ceramic disk to provide fine water particles delivered by a pump to the HFPV circuit. This new device may alleviate previous concerns related to the delivery of adequate humidification with the HFPV. This case report was approved by the University of North Carolina School of Medicine Institutional Review Board.
从历史上看，在许多烧伤中心使用的高频震荡通气机（HFPV）很难提供足够的湿化。由于存在黏液堵塞、分泌物干结和结痂形成的风险，烧伤中心可能一直避免使用HFPV。HFPV的使用经验让人怀疑HFPV通气回路能否为接受这种通气模式的患者提供足够的湿化。HFPV固有的通过通气回路独立输送气体的方式，给维持向患者提供足够的湿化带来了挑战。本报告描述了通过使用一种新型的HFPV湿化装置，干结、浓缩分泌物显著减少。这种名为Hydrate Omni（弗吉尼亚州米德洛锡安的Hydrate公司）的新装置使用一个小陶瓷盘，通过泵将细小的水颗粒输送到HFPV回路。这种新装置可能会消除此前与HFPV提供足够湿化相关的担忧。本病例报告经北卡罗来纳大学医学院机构审查委员会批准。
