本研究的目的是建立一个有效的标准化方法来评估超声动力学。40名健康志愿者接受了B和M型超声研究，使用位于肋下前部区域的凸形换能器进行横向扫描。超声检查完成率为95%（38/40），平均检查时间为10 min。静息和强制性脑电偏移分别为18.4 ± 7.6和78.8 ± 13.3 mm，与人口统计学或人体测量学参数无关：连续三次测量的观察者内变异性分别为6.0%和3.9%。在40例病例中，37例由经验不足的超声医师完成超声检查，平均花费>15分钟，观察者间差异显著（尽管边缘）（静息和强迫脑偏移分别为31.9%和14.7%）。通过对半卧位患者进行前肋下横向扫描的床旁超声检查被证明是一种安全、可行、可靠、快速、相对容易和可重复的评估膈肌运动的方法。（电子邮件：americotesta@gmail.com）（C）2011年世界医学和生物学超声联合会。
The purpose of this study was to set an effective standardized method to assess diaphragmatic kinetics by ultrasound. Forty healthy volunteers were submitted to a B- and M-mode ultrasound study using a convex transducer positioned in the subcostal anterior area for transverse scanning. Ultrasound examination was completed in 38/40 cases (95%), spending on average,10 min for examination. The resting and forced diaphragmatic excursions were 18.4 +/- 7.6 and 78.8 +/- 13.3 mm, respectively, unrelated to demographic or anthropometric parameters: intraobserver variability on three successive measurements resulted in 6.0% and in 3.9%, respectively. An inexperienced sonographer completed the ultrasound examination in 37/40 cases, spending on average >15 min, with significant, although marginal, interobserver variability (31.9% and 14.7% for resting and forced diaphragmatic excursion, respectively). Bedside ultrasonography by an anterior subcostal transverse scanning on semi-recumbent patient proves to be a safe, feasible, reliable, fast, relatively easy and reproducible way to assess diaphragm movement.
