A multilumen catheter guide (jet stylet) with an adapter has been used for various manoeuvres in the upper airway. With the split length, procedures such as change of tracheal tube from oral to nasal nasal to oral position, are possible while the patient's lungs are ventilated by means of high frequency jet ventilation. During high frequency jet ventilation for longer periods of time, for example for microlaryngeal surgery, the central channel of the catheter is used as a conduit for jet delivery, whilst the other channels are used for continuous monitoring of airway pressure and concentration of carbon dioxide in the upper airway.
一种带有适配器的多腔导管导向器（喷射探条）已用于上气道的各种操作。凭借其可拆分的长度，在通过高频喷射通气对患者肺部进行通气的同时，可以进行诸如将气管导管从口腔位置更换到鼻腔位置或从鼻腔位置更换到口腔位置等操作。在长时间进行高频喷射通气时，例如在显微喉镜手术中，导管的中央通道用作喷射输送的管道，而其他通道则用于持续监测气道压力和上气道中的二氧化碳浓度。
