Non-expandable lung (NEL) commonly occurs secondary to chronic pleural processes, including pleural effusions, endobronchial obstruction, atelectasis, or chronic pleural inflammatory processes. Patients with NEL frequently undergo unnecessary procedures (e.g., thoracentesis), resulting in pneumothorax and discomfort (usually chest pain). Identifying a chronic process and likely development of NEL may prevent this. Diagnostic modalities currently used in practice include pleural manometry and ultrasonography. This case report demonstrates that blunting of transmitted cardiac impulse on M-Mode of ultrasonography predicts the presence of NEL.
不可扩张肺（NEL）通常继发于慢性胸膜病变，包括胸腔积液、支气管内阻塞、肺不张或慢性胸膜炎症过程。NEL患者经常接受不必要的操作（如胸腔穿刺术），导致气胸和不适（通常为胸痛）。识别慢性病变以及NEL的可能发展情况可预防此类情况。目前在实践中使用的诊断方法包括胸膜测压法和超声检查。本病例报告表明，超声心动图M型上心脏搏动传导减弱可预测NEL的存在。
