I'm a bit concerned about my x-ray report showing prominent broncho vascular markings, especially since I have a history of bronchitis. I'm 51 years old and commute for 2 hours daily. My previous PFT report was okay, but could this be something serious?

Your x-ray report showing prominent broncho vascular markings could be indicative of bronchitis or inflammation in the airways. Given your history of bronchitis and daily travel of 2 hours, it is important to manage this condition to prevent any exacerbation. I would recommend using an inhaler like Salbutamol (Ventolin) 2 puffs every 4-6 hours as needed for bronchospasm. Additionally, you can use an inhaled corticosteroid like Fluticasone (Flovent) 2 puffs twice daily to reduce airway inflammation. It is also important to stay hydrated, avoid exposure to smoke or pollutants, and consider wearing a mask during your daily commute to protect your airways. Regular follow-up with your doctor for monitoring and possible repeat PFT testing is advisable to ensure optimal lung function.
