In June 2021, Philips Respironics first advised the use of in-line bacterial filters in response to a recall of continuous positive airway pressure (CPAP) devices. However, the effects of using in-line filters with CPAP devices have not yet been examined in a clinical setting. Here, we retrospectively evaluated 160 patients with sleep-disordered breathing (SDB) who voluntarily used in-line bacterial filters. Patients' perceptions of CPAP pressure after using in-line filters were investigated via a verbal interview. Patients described CPAP pressure as very weak (13, 8.1%), somewhat weak (42, 26.2%), unchanged (103, 64.4%), or somewhat strong (2, 1.3%). Five of the thirteen patients (38.5%) who described CPAP pressure as very weak discontinued the use of in-line filters. The apnea-hypopnea index obtained from the CPAP devices did not change after using in-line filters (n = 129, p = 0.85). Hence, although in-line bacterial filters could change patients' perceptions of CPAP pressure, they did not influence SDB control.
2021 年 6 月，飞利浦伟康公司首次建议在持续气道正压通气（CPAP）设备中使用在线细菌过滤器，以应对 CPAP 设备的召回。然而，在临床环境中尚未对 CPAP 设备中使用在线过滤器的效果进行检查。在这里，我们回顾性评估了 160 名自愿使用在线细菌过滤器的睡眠呼吸障碍（SDB）患者。通过口头访谈调查了患者在使用在线过滤器后对 CPAP 压力的感知。患者将 CPAP 压力描述为非常弱（13 例，8.1%）、有点弱（42 例，26.2%）、不变（103 例，64.4%）或有点强（2 例，1.3%）。在描述 CPAP 压力非常弱的 13 名患者中，有 5 名（38.5%）停止使用在线过滤器。使用在线过滤器后，CPAP 设备获得的呼吸暂停低通气指数没有变化（n=129，p=0.85）。因此，尽管在线细菌过滤器可以改变患者对 CPAP 压力的感知，但它们不会影响 SDB 的控制。
