2 levels and increased respiratory symptoms such as wheeze, chest tightness and severity of infections among children with asthma. [6] Historically, some cities in the United States including Chicago and Los Angeles have higher levels of nitrogen dioxide than the EPA maximum exposure limits of 100 ppb for a one-hour exposure and less than 53 ...
Acute harm due to NO 2 exposure is rare. 100–200 ppm can cause mild irritation of the nose and throat, 250–500 ppm can cause edema, leading to bronchitis or pneumonia, and levels above 1000 ppm can cause death due to asphyxiation from fluid in the lungs. There are often no symptoms at the time of exposure other than transient cough, fatigue ...
Furthermore, drugs used to treat asthma (such as inhaled glucocorticoids or leukotriene receptor antagonists) also reduce eNO levels. Clinical trials have looked at whether tailoring asthma therapy based on eNO values is better than conventional care, in which therapy is gauged by symptoms and the results of lung function tests.
This is a problem, the researchers said, because NO2 exposure over time can make asthma attacks worse and has been linked to affecting children's lung development.
Occupational asthma is new onset asthma or the recurrence of previously quiescent asthma directly caused by exposure to an agent at workplace. It is an occupational lung disease and a type of work-related asthma. Agents that can induce occupational asthma can be grouped into sensitizers and irritants. [1]

An asthma attack can also feel a little like a panic attack in some situations. “But asthma can also cause anxiety, so they can double up on each other,” says Dr. Mustafa.
GERD may be common in difficult-to-control asthma, but according to one study, treating it does not seem to affect the asthma. [33] When there is a clinical suspicion for GERD as the cause of the asthma, an Esophageal pH Monitoring is required to confirm the diagnosis and establish the relationship between GERD and asthma.
