概括
硫六化物 (SF6) 洗和洗阶段的多呼吸洗 (MBW) 结果在婴儿中是不相似的. 这些在健康患者和囊性纤维化患者中观察到的差异超过了自然变异性,不能互换使用.
科学领域:
- 肺部生理学 肺部生理学
- 呼吸系统医学 呼吸系统医学
- 医疗器械技术 医疗器械技术
背景情况:
- 硫六化物 (SF6) 多重呼吸洗 (MBW) 是评估通风不均性的关键方法.
- 它是阻塞性呼吸道疾病的早期指标.
- 主要的MBW结果通常来自washout阶段,washin阶段的可比性不清楚.
研究的目的:
- 评估washin和washout阶段之间初级SF6-MBW结果的可比性.
- 为了评估婴儿SF6-MBW数据来自WBreath和Spiroware设置.
- 为了确定washin和washout结果是否可以互换使用.
主要方法:
- 对现有的SF6-MBW从健康婴儿和患有囊性纤维化 (CF) 的婴儿的数据进行分析.
- 计算washin和washout之间的肺清除指数 (LCI) 和功能剩余容量 (FRC) 的平均相对差异.
- 将这些差异与试验之间的差异和使用儿科肺部模拟器评估之间的平均相对内测差异进行比较.
主要成果:
- 来自washin和washout阶段的肺清除指数 (LCI) 和功能残留容量 (FRC) 在WBreath和Spiroware设置中是不可比较的.
- 在washin和washhout之间观察到的LCI和FRC的平均差异超过了自然的变化.
- 儿科肺部模拟器证实了washin和washout结果之间缺乏可比性.
结论:
- SF6-从washin和washout阶段的MBW结果在婴儿中是不可互换的.
- 这些差异归因于生理和非生理因素的相互作用.
- 这凸显了使用一致的相位数据来准确解释通风不均的重要性.

50.7K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
1.8K
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

2.0K
Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
