摘要

简介。本文详细介绍了一种低成本定制 RMST 设备的开发和使用情况,该设备适用于一名在重症监护室治疗期间接受过气道正压流量支持的长 COVID 患者。通过分享我们对重症 COVID-19 患者呼吸肌无力的成功治疗,我们希望为更广泛地讨论长 COVID 的有效治疗做出贡献。病例描述。一名呼吸肌无力患者使用了医院自制的 RMST 设备。训练包括每个周期 10 次短促用力呼气,持续 5 个周期,然后保持 5 秒钟长促用力呼气。此外,患者还学习了下腹部和箱式呼吸技巧。患者的情况有了明显改善,在 24 小时内无需补充氧气即可使用 RMST 设备,并在第 5 天完全断奶。出院时,患者可以完成 RMST 运动,并在 6MWT 中跑了 290 米。经过六周的门诊治疗,患者在 80 厘米水下使用 RMST 设备,6MWT 距离增加到 390 米。设备描述。RMST 设备是为内部生产而设计的,采用 3D 打印 PETG 盖帽、底座、活塞和标准钢笔弹簧。其设计模仿了不同几何形状的标准 PEEP 阀。弹簧关闭阀门,直到达到压力阈值,允许气流流动。可调节的压力阈值范围为 -40 至 +40 cm H2O,通过测量移位的水柱高度,以 10 cm H2O 为增量进行校准。讨论和局限性。COVID-19 可导致长期的呼吸问题,需要适当的治疗和康复。吸气肌肉训练对那些从机械通气中断气的重度 COVID-19 患者有好处。然而,该设备的设计和生产方法不适合大规模商业化生产。康复中心应为 COVID-19 后患者的重症监护后综合症做好准备,由跨专业团队负责各方面的康复工作。早期医疗护理和治疗可提高患者的生活质量。

Use of Locally Produced Novel Low-Cost 3D Printed Respiratory Muscle Strength Trainer Device (RMSTD) for Long COVID-Rehabilitation: An Innovative Case Report.

Introduction. This article details the development and use of a low-cost, custom RMST device for a patient with long COVID who had received positive airway flow support during ICU treatment. By sharing our successful management of respiratory muscle weakness in a severe COVID-19 patient, we aim to contribute to the broader conversation around effective long COVID management. Case Description. A patient with respiratory muscle weakness used a hospital-made RMST device. The training involved ten short forced exhalations per cycle for five cycles, followed by five long forced exhalations held for five seconds. Additionally, the patient learned lower abdominal and box breathing techniques. The patient showed significant improvement, using the RMST device without supplemental oxygen within 24 hours and completely weaned off by day 5. By discharge, the patient could complete the RMST exercise regime and achieved 290 meters in the 6MWT. After six weeks of outpatient therapy, the patient used the RMST device at 80 cm H2O and increased their 6MWT distance to 390 meters. Device Description. The RMST device was designed for in-house production with a 3D-printed PETG cap, base, and plunger, and a standard pen spring. Its design mimicked a standard PEEP valve with a different geometry. The spring closed the valve until a pressure threshold was reached, allowing airflow. The adjustable pressure threshold ranged from -40 to +40 cm H2O, calibrated in 10 cm H2O increments by measuring displaced water column height. Discussion and Limitation. COVID-19 can cause long-term respiratory issues needing proper management and rehabilitation. Inspiratory muscle training benefits those recovering from severe COVID-19 who were weaned from mechanical ventilation. However, the device's design and production method are unsuitable for large-scale and commercial production. Rehabilitation centers should prepare for postintensive care syndrome in post-COVID-19 individuals, with interprofessional teams addressing various recovery aspects. Early medical attention and therapy can improve patients' quality of life.
