Chest & Breathing Problems

My brother is diagnosed Pleurisy &Pneumonia. After 11 days of antibiotics through IV, pleural effusion still continues. Doctor planning for biopsy as the cause is unclear. Pleural fluid tests came negative for tb, culture and malignancy. So please advise what can be the possible causes for it.

Doctor, yesterday I took PFT Test( spirometry) , required for employment in petroleum refinery. In the resultant graph the peak of the graph crossed 7 on y-axis But online I read that volume should be minimum 80% of the predicted value. So does that mean I have failed the test or the peak at 7 is just normal and I have to consider other parameters too.? Please reply asap

Doctor, I have yesterday gone through medical check up( needed for employment in petroleum refinery). I consider myself completely fit and don't have any breathing problem. Yet when I took PFT Test( spirometry), the reading in the resultant graph just passed 6 or 7. So does this mean that I am medically unfit??? Or its just normal. Online I read that the value on the graph should pass 8. I am really worried since my future is dependent on it. Please help me as soon as possible.

Hi Dr. My mother is ILD (Interstitial Lungs Disease) and CKD patient. She was prescribed Metosartan 50 (with composition Telmisartan 40mg+Metoprolol Succinate 50mg) to control high BP. But other Physician stopped it saying not safe for her and it reduces heart or pulse rate as well. Is it safe for her? Please advise. Thanks.

Yesterday I slept by turning on the air conditioner. I mistakenly/accidentally used it in dry mode. I live in Rajasthan,the humidity here is low, and the humidity of my room became more low due to use of the air conditioner in dry mode. I am feeling discomfort in breathing. Will anything happen to me? Has my lung dried up?
