The inspiratory timing of lung crackles in patients with bronchiectasis was compared with the inspiratory timing of the lung crackles in chronic bronchitis and alveolitis. In severe obstructive chronic bronchitis the lung crackles are typically confined to early inspiration while in alveolitis the lung crackles continue to the end of inspiration but may begin in the early or the mid phase of inspiration. In uncomplicated bronchiectasis on the other hand, the lung crackles typically occur in the early and mid phase of inspiration, are more profuse, and usually fade by the end of inspiration. In addition in bronchiectasis, crackles are also usually present in expiration, they are gravity independent and become less profuse after coughing.
对支气管扩张症患者肺部啰音的吸气时间与慢性支气管炎和肺泡炎患者肺部啰音的吸气时间进行了比较。在严重阻塞性慢性支气管炎中，肺部啰音通常局限于吸气早期，而在肺泡炎中，肺部啰音持续到吸气末，但可能在吸气早期或中期开始。另一方面，在无并发症的支气管扩张症中，肺部啰音通常出现在吸气早期和中期，更为丰富，通常在吸气末消失。此外，在支气管扩张症中，啰音在呼气时通常也存在，它们与重力无关，咳嗽后会变少。
