膈肌超声（DUS）已用于识别膈肌功能障碍。然而，其与呼吸强度和肺功能的相关性尚不清楚，即使在健康患者中也是如此。共64例健康患者（30例男性）进行了肺功能和吸气强度（最大吸气压和鼻吸气压）的测量。在一个亚组（n = 40）中测量胃和食管压力。DUS的特征为活动性（安静呼吸[QB]和深呼吸[DB J]）和厚度（功能残气量[Th-FRC]和总肺活量[Th-TLC]）。我们计算了增稠分数（TF）。QB期间，性别间DUS相似。然而，在DB，女性有较低的流动性，厚度和TF比男性。DB、Th-TLC和TF的迁移率与肺功能和吸气强度显著相关。这些相关性受到性别的影响。DUS与吸气胃压相关。在健康患者中，DUS与DB期间的肺功能和吸气强度相关。在DB期间进行DUS时，性别之间的显著差异是明显的。(C)2018年世界医学和生物学超声联合会。All rights reserved.
Diaphragm ultrasound (DUS) has been used to identify diaphragm dysfunction. However, its correlations with respiratory strength and lung function are unclear, even in healthy patients. A total of 64 healthy patients (30 males) had lung function and inspiratory strength (maximal inspiratory pressure and sniff nasal inspiratory pressure) measured. Gastric and oesophageal pressures were measured in a subgroup (n = 40). DUS was characterized by mobility (quiet breathing [QB] and deep breathing [DB J) and thickness (at functional residual capacity [Th-FRC] and total lung capacity [Th-TLC). We calculated the thickening fraction (TF). During QB, DUS was similar between sexes. However, during DB, females had lower mobility, thickness and TF than males. Mobility at DB, Th-TLC and TF significantly correlated with lung function and inspiratory strength. These correlations were affected by sex. DUS correlated with inspiratory gastric pressure. In healthy patients, DUS correlated with lung function and inspiratory strength during DB. Significant differences between genders were noticeable when DUS was performed during DB.
