异常的冲动振荡计 (IOS) 发现在具有螺旋计模式的个体中很常见,例如保留比率受损螺旋计 (PRISm) 和限制性螺旋计模式 (RSP). 这些异常的IOS结果有助于解释呼吸系统症状和受影响患者的病假增加.
科学领域:
- 肺部医学 肺部医学
- 呼吸系统生理学 呼吸系统生理学
- 诊断成像诊断成像的使用
背景情况:
- 保留比率受损螺旋计 (PRISm) 和限制性螺旋计模式 (RSP) 与较高的发病率和死亡率有关.
- 这些螺旋测量模式的潜在机制仍然不清楚.
- 脉冲振荡计 (IOS) 提供了敏感的小气道功能评估,超过了螺旋计.
研究的目的:
- 调查不同螺旋测量模式 (阻塞性,PRISM,RSP) 中异常IOS发现的流行情况.
- 检查异常IOS指数与呼吸系统症状之间的关联.
- 探索异常IOS发现,螺旋测量模式和呼吸系统相关病假之间的联系.
主要方法:
- 分析了来自瑞典心肺生物图像研究 (SCAPIS) 的10,360名参与者 (年龄在50-64岁) 的数据.
- 同时评估IOS和螺旋计.
- 调查问卷被用来收集有关呼吸道症状的数据.
- 从健康的,从不吸烟的参与者中建立了参考值;异常被定义为<5或>95百分位.
主要成果:
- 在螺旋计组中异常的IOS指数普遍存在:31% (阻塞性),38% (PRISm),28% (RSP) 和40% (PRISm+RSP).
- 异常的IOS与呼吸系统症状有关,包括阻塞性和RSP组的喘息,以及PRISM组的呼吸障碍.
- 在阻塞性和PRISm+RSP组中观察到呼吸系统相关的病假增加,后者的风险最高.
结论:
- 异常冲动振荡计 (IOS) 指数经常在异常螺旋计模式的个体中观察到.
- IOS的发现为改变螺旋计的患者所经历的呼吸系统症状提供了部分解释.
- IOS可以提供有关螺旋计异常的功能后果的有价值的见解.

Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

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:

Alterations in Respiration II
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...
