If you have a chronic heart or lung problem, an inhalation injury can make it worse.

To make a diagnosis, your health care provider may use a scope to look at your airways and check for damage. Other possible tests include imaging tests of the lungs, blood tests, and lung function tests.

If you have an inhalation injury, your health care provider will make sure that your airway is not blocked. Treatment is with oxygen therapy, and in some cases, medicines. Some patients need to use a ventilator to breathe. Most people get better, but some people have permanent lung or breathing problems. Smokers and people who had a severe injury are at a greater risk of having permanent problems.
