No study has yet evaluated the degree of contamination after the total disassembly of continuous positive airway pressure (CPAP) devices. We investigated the extent of contamination of CPAP devices used daily by patients with obstructive sleep apnea (OSA) by disassembling the systems and identifying the factors that influenced the degree of CPAP contamination.
We conducted a chart review of the medical records of patients with OSA for whom the CPAP devices were disassembled and cleaned. Two skilled technicians photographed the levels of contamination of each component and scored them using a visual analog scale. Patients' clinical characteristics and records of CPAP device usage were statistically analyzed to identify characteristics that were significantly associated with the degree of CPAP device contamination.
Among the 55 participants, both the external components, including the mask and tube, and the internal components, such as the humidifier and the interior of the main body, showed a substantial degree of contamination. The total and average daily duration of usage of the CPAP device did not show significant associations with the degree of contamination. Age was most consistently associated with the degree of contamination, such as in masks, humidifiers, and interior and exterior main parts. The degree of contamination of the internal components of the device was significantly correlated with the degree of contamination of the external components.
Age-specific guidelines for managing the hygiene of external and internal CPAP components should be prepared.
尚无研究评估持续气道正压通气（CPAP）设备完全拆解后的污染程度。我们通过拆解系统并确定影响CPAP污染程度的因素，调查了阻塞性睡眠呼吸暂停（OSA）患者日常使用的CPAP设备的污染程度。
我们对CPAP设备已拆解并清洁的OSA患者的病历进行了图表审查。两名技术熟练的技术人员拍摄了每个组件的污染程度，并使用视觉模拟量表对其进行评分。对患者的临床特征和CPAP设备使用记录进行统计分析，以确定与CPAP设备污染程度显著相关的特征。
在55名参与者中，包括面罩和管道在内的外部组件以及加湿器和主体内部等内部组件均显示出相当程度的污染。CPAP设备的总使用时长和日均使用时长与污染程度均无显著关联。年龄与污染程度的相关性最为一致，如在面罩、加湿器以及主体内外部分。设备内部组件的污染程度与外部组件的污染程度显著相关。
应制定针对不同年龄的CPAP设备内外组件卫生管理指南。
