Although helium offers an additional tool in the treatment of various airway and pulmonary problems, it has no inherent therapeutic effects. As such, it can be used only as a temporizing agent to allow time for therapeutic agents to work or for the natural resolution of the disease process. It may also allow time for optimal planning when dealing with difficult problems such as upper airway obstruction. While the majority of clinical experience describes its use for obstructive lesions of the glottic/subglottic areas, it may also be of benefit in conditions that narrow the more distal airways, including asthma. Given its beneficial physiologic effects, it seems that future studies are warranted to evaluate its efficacy in other disease processes.
尽管氦气为各种气道和肺部问题的治疗提供了一种额外的手段，但它本身并没有治疗作用。因此，它只能用作一种临时药物，以便为治疗药物发挥作用或疾病过程自然缓解留出时间。在处理诸如上气道阻塞等难题时，它也可为进行最佳规划留出时间。虽然大多数临床经验描述了其用于声门/声门下区域阻塞性病变的情况，但它在使更远端气道变窄的病症（包括哮喘）中可能也有益处。鉴于其有益的生理效应，似乎有必要进行进一步研究以评估其在其他疾病过程中的疗效。
