研究目的: |
根据《中国心血管健康与疾病报告 2022》的数据统计,保守估计,我国约有 400 万心力衰竭(心衰)患者。80%以上心衰患者伴随不同程度的呼吸困难。随着病情的加重,呼吸困难的程度也随之加重,加重氧供和氧需的不平衡,影响患者的生活质量。 呼吸康复可提高患者呼吸肌力,提高呼吸效率。但目前呼吸康复治疗中,缺乏对患者呼吸及肺通气状况的实时评估手段,缺少可视化的设备便于及时调整康复治疗的处方。传统的肺部成像技术如 X 射线或 CT,有放射性,且无法实时动态监测,存在局限性。 电阻抗断层成像(EIT)是一项全新的医学成像技术,与传统成像系统相比,具有非侵入性,无辐射,区域性连续监测的特点。EIT 可监测胸部周围的边界电压变化。尽管随着技术的革新,EIT 的成像速度已达到 20-40 帧/秒,但 EIT 是否可以实现实时的呼吸曲线成像尚 未被证实。当患者被给予主动或被动的呼吸训练时,在吸气相促进以膈肌为主的呼吸肌收缩,在呼气相促进 CO2 排出,是十分必要的。呼吸康复与患者自身呼吸频率协同不仅可以提高锻炼的效率,还能避免呼吸肌疲劳。当临床人员根据 EIT 的图像指导患者呼吸康复,EIT 图像的准确性和实时性就成为了呼吸康复有效性的基础。基于此,本研究拟探讨 EIT 技术对心衰患者进行呼吸监测的同步性,评价 EIT 是否可以实时获得患者的呼吸曲线。 本项研究中使用的 EIT,是由苏州健通医疗科技有限公司研发的,是国家药品监督管理局已批准上市的医疗器械。本项研究是观察性研究,不对研究参与者进行任何干预,使用的设备不影响心衰治疗。 |

Objectives of Study: |
Based on statistics from the China Cardiovascular Health and Disease Report 2022, it is conservatively estimated that there are approximately 4 million patients with heart failure (HF) in China. Over 80% of HF patients experience varying degrees of dyspnea. As the condition worsens, the severity of dyspnea increases, exacerbating the imbalance between oxygen supply and demand and affecting patients' quality of life. Pulmonary rehabilitation can improve patients' respiratory muscle strength and breathing efficiency. However, current pulmonary rehabilitation therapies lack real-time assessment methods for monitoring patients' breathing and pulmonary ventilation status, as well as visualization equipment to facilitate timely adjustments to rehabilitation prescriptions. Traditional lung imaging techniques, such as X-rays or CT, have limitations due to radiation exposure and the inability to provide real-time dynamic monitoring. Electrical Impedance Tomography (EIT) is a novel medical imaging technology that, compared to traditional imaging systems, is non-invasive, radiation-free, and capable of continuous regional monitoring. EIT can monitor changes in boundary voltages around the chest. Although technological advancements have increased EIT imaging speeds to 20-40 frames per second, whether EIT can achieve real-time respiratory curve imaging has not yet been confirmed. When patients undergo active or passive breathing training, it is essential to promote contraction of the diaphragm-dominant respiratory muscles during the inspiratory phase and facilitate CO2 expulsion during the expiratory phase. Synchronizing pulmonary rehabilitation with the patient's own respiratory rhythm not only enhances exercise efficiency but also prevents respiratory muscle fatigue. When clinicians use EIT images to guide pulmonary rehabilitation, the accuracy and real-time performance of EIT images become the foundation for the effectiveness of the rehabilitation. Based on this, this study aims to investigate the synchrony of EIT technology in monitoring the breathing of HF patients and evaluate whether EIT can acquire patients' respiratory curves in real time. The EIT device used in this study was developed by Suzhou Jiantong Medical Technology Co., Ltd. and is a medical device approved for market by the National Medical Products Administration. This study is an observational study; no interventions will be performed on the study participants, and the use of the device will not affect the heart failure treatment. |
