Pulmonary function assessment in laryngectomized patients is challenging due to technical difficulties in performing spirometry. Existing methods have limitations, including potential air leakage and patient discomfort. The purpose of this study was to develop a simple, comfortable extratracheal device for accurate pulmonary function assessment in laryngectomized patients.
We designed a silicone extratracheal device with a central connector for spirometer attachment and an adhesive layer for secure skin fixation. Ten laryngectomized patients underwent spirometry using the device. Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), and FEV1/FVC ratio were measured and compared to predicted values.
The extratracheal device was validated after performing successful spirometric tests in 10 laryngectomized patients, maintaining the necessary air seal to ensure the accuracy of the results, with no air leakage. Pulmonologists evaluating the device found it to be technically adequate for report generation.
The developed extratracheal device has proven to be reliable and effective for assessing pulmonary function in laryngectomized patients, potentially serving as a valuable tool for regular pulmonary function monitoring in this population.
由于在喉切除患者中进行肺活量测定存在技术困难，对其进行肺功能评估具有挑战性。现有方法存在局限性，包括潜在的漏气和患者不适。本研究的目的是开发一种简单、舒适的气管外装置，用于准确评估喉切除患者的肺功能。
我们设计了一种硅胶气管外装置，带有用于连接肺活量计的中央连接器和用于牢固固定在皮肤上的粘合层。10名喉切除患者使用该装置进行了肺活量测定。测量了用力肺活量（FVC）、一秒用力呼气量（FEV1）和FEV1/FVC比值，并与预测值进行比较。
在10名喉切除患者中成功进行肺活量测定后，该气管外装置得到验证，保持了必要的气密以确保结果的准确性，无漏气现象。评估该装置的肺科医生发现其在技术上足以生成报告。
已开发的气管外装置已被证明在评估喉切除患者的肺功能方面可靠且有效，有可能成为该人群定期肺功能监测的有价值工具。
