肥胖的年轻人表现出改变的呼吸模式和增加的呼吸变化,即使在休息. 这些变化可能标志着与肥胖相关的呼吸系统问题的风险更高.
科学领域:
- 身体生理学 身体生理学
- 肺部病理学 肺部病理学
- 儿科健康 儿科健康
背景情况:
- 呼吸模式的变化与各种疾病有关.
- 肥胖会影响胸部机制,可能会改变呼吸模式.
- 关于肥胖年轻人呼吸模式和可变性的数据有限.
研究的目的:
- 评估肥胖的年轻人呼吸模式的变化.
- 为了调查这个人口群体的呼吸模式变化.
主要方法:
- 将47名肥胖的年轻患者与47名年龄/性别匹配的对照组 (平均年龄17.6岁) 进行比较.
- 采用呼吸道诱导性胸膜学来记录潮体积和吸气/呼气持续时间的呼吸到呼吸.
- 计算的呼吸周期持续时间 (Ttot),呼吸速率 (fR),每分钟通风 (MV),工作周期 (Ti/Ttot),平均吸入流量 (Vt/Ti) 和快速浅呼吸指数 (fR/Vt).
- 使用标准偏差 (SD) 和变化系数 (CV) 量化变化.
主要成果:
- 肥胖患者在休息时出现潮体积 (Vt) 减少和呼吸速率 (fR) 增加.
- 缩短的呼吸时间导致肥胖组的Ti/Ttot比率增加.
- 肥胖个体的快速浅呼吸指数 (fR/Vt) 显着更高.
- 在肥胖患者中观察到呼吸速率,每分钟通风,呼吸流,Ti/Ttot和FR/Vt的变化增加,特别是在休息状态下.
结论:
- 肥胖的年轻人出现呼吸模式的早期变化和呼吸变化增加.
- 这些变化可能成为肥胖相关呼吸道并发症的潜在早期标志物.

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:
