INTRODUCTION Chest X-ray (CXR) is the most prevalent method for evaluating lung expansion in high-frequency oscillatory ventilation (HFOV). The purpose of this study was to compare the accuracy of chest radiography with point-of-care ultrasound (POCUS) in determining lung expansion. METHODS This prospective study included newborns who required HFOV and were monitored in a neonatal intensive care unit. A single neonatologist assessed lung expansion with CXR and POCUS to measure the costal level of the right hemidiaphragm and compared the results. RESULTS A neonatologist performed 55 measurements in 28 newborns with a gestational age of 32 (23.2-39.4) weeks, followed by HFOV. The rib counts obtained from anterior chest ultrasonography and posterior CXR showed a statistically high concordance (r = 0.913, p < 0.001). CONCLUSION Lung ultrasonography is a reliable method for the evaluation of lung expansion based on rib count in patients with HFOV.

护理点超声与胸部 X 光检查基于高频振荡通气中的肋骨计数来确定肺扩张。

简介 胸部 X 射线 (CXR) 是评估高频振荡通气 (HFOV) 中肺扩张的最常用方法。本研究的目的是比较胸部 X 光检查与护理点超声 (POCUS) 在确定肺扩张方面的准确性。方法 这项前瞻性研究纳入了需要 HFOV 并在新生儿重症监护病房接受监测的新生儿。一名新生儿科医生使用 CXR 和 POCUS 评估肺扩张情况，测量右侧膈肌的肋水平，并比较结果。结果 一名新生儿科医生对 28 名胎龄为 32 (23.2-39.4) 周的新生儿进行了 55 次测量，随后进行了 HFOV。从前胸部超声检查和后 CXR 获得的肋骨计数显示出统计学上的高度一致性（r = 0.913，p < 0.001）。结论 肺部超声检查是根据肋骨计数评估 HFOV 患者肺扩张情况的可靠方法。
