my wife was known to have pneumonia. For six days strong antibiotics have been administered .The cumus is said to have accumulated in the bottom part of her lungs But coughing does not help her to get rid of that. Slight fever continues despite the antibiotics. No infection in the blood is seen now. Her heart is in good shape. Her breathing is normal .But the doctor thinks that my wife is week and cannot breath with enough strength and therefore the cumus accumulated in her lung cannot come out while coughing./ He thinks branchitoscopy may be the solution. Is that a good soluton? If yes ,why?
