The pathophysiology of a tension pneumothorax relates to ventilation and cardiac output. The insertion of a large-bore needle or medium-bore catheter into the affected pleural cavity rapidly accomplishes decompression. The McSwain Dart was developed for the prehospital care of tension pneumothorax. The dart is inserted into the secondary costal space, mid-clavicular line, or the fourth intercostal space mid-axillary line. Proper identification of the indications for use of this device is often difficult in the prehospital setting.
张力性气胸的病理生理学与通气和心输出量有关。将大口径针或中口径导管插入受影响的胸腔可迅速实现减压。麦克斯文飞镖是为院前张力性气胸护理而开发的。飞镖插入第二肋间隙、锁骨中线或腋中线第四肋间。在院前环境中，正确识别该设备的使用指征往往很困难。
