功能障碍的呼吸模式,以运动期间呼吸频率增加为特征,在喘患者中显著恶化运动诱导的呼吸障碍 (呼吸短促). 这凸显了在喘管理中解决呼吸模式的必要性.
科学领域:
- 肺部病理学 肺部病理学
- 呼吸系统生理学 呼吸系统生理学
- 运动医学 运动医学
背景情况:
- 大约25%的喘患者患有呼吸功能障碍,导致运动诱导性呼吸障碍 (EID).
- 常常误认为EID仅仅是支气管收缩,忽视了功能障碍呼吸的影响.
- 这种监督可能会导致喘患者经历EID的治疗策略不足.
研究的目的:
- 为了研究和比较在炼期间控制良好的喘患者和健康个体的呼吸模式.
- 确定这些呼吸模式对运动诱导性呼吸障碍 (EID) 严重性的影响.
主要方法:
- 一项涉及15名喘患者和15名健康受试者的横截面研究.
- 心肺运动测试 (CPET) 用于通过一种新的呼吸模式 (BP) 角度参数来评估呼吸模式.
- 使用视觉模拟量表 (VAS) 和博格分数量化呼吸障碍.
主要成果:
- 呼吸模式 (BP) 角度和其他CPET参数在喘患者和健康人群之间是可比的.
- 两组的子组 (n=6) 均表现出血压角<45°,这表明在运动中期呼吸相对快速,浅.
- 这些血压角度较低的受试者在最大运动时报告了明显更高的呼吸障碍水平,相比之下,血压角度> 45°.
结论:
- 通过血压角度测量,在中级运动期间呼吸频率的增加与呼吸障碍的感觉增加有关.
- 功能障碍的呼吸模式是喘患者中EID发展的重要因素.
- 这些发现强调了在综合性喘管理中识别和解决功能障碍呼吸的重要性.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
