Which is NOT a respiratory disqualifying condition?

Chronic bronchitis is classified as a chronic obstructive pulmonary disease (COPD), which can be stable in many individuals. If a person with stable chronic bronchitis does not present acute symptoms that interfere with their daily activities, particularly their ability to perform required job functions, they may not be disqualified from certain medical examinations, such as those conducted by the Department of Transportation (DOT).

In contrast, conditions such as uncontrolled sleep apnea and chronic cough with cough syncope can significantly impair a person's ability to operate a vehicle safely. Uncontrolled sleep apnea can lead to excessive daytime sleepiness and a higher risk of accidents, while coughing that leads to syncope (a loss of consciousness) creates direct danger to the individual and others on the road. Oxygen therapy implies a need for supplemental oxygen due to respiratory compromise, which is also typically disqualifying as it suggests significant respiratory issues. Thus, stable chronic bronchitis is positioned as the condition that does not automatically disqualify someone from assessment for driving tasks.
