A driver has had his second spontaneous pneumothorax on the same side 3 months ago. What is the correct determination in this case?

The determination to not certify a driver until the condition has been corrected surgically is based on the potential risks associated with spontaneous pneumothorax, especially when it occurs multiple times on the same side. A spontaneous pneumothorax can lead to serious complications, including recurrence, respiratory distress, and sudden incapacitation, which would be particularly dangerous in a driving scenario.

In cases of recurrent pneumothorax, the medical assessment leans toward caution because both the reliability of the driver's lung function and the stability of their condition are paramount. Surgical correction is often required to prevent further episodes, and until that is achieved, the individual may not be fit to safely operate a vehicle. Therefore, the best course of action is to require surgical intervention before considering certification, ensuring the driver is safe on the road.

Other options suggest certification under certain conditions related to pulmonary function or oxygen saturation, but these parameters do not adequately address the underlying issue of recurrent pneumothorax and the associated risks. Hence, not certifying until surgical correction is the most prudent choice to safeguard public safety.
