<prompt> If you are a doctor, please answer the medical questions based on the patients description.My daughter was diagnosed with transient tachypnea 6 days ago after birth. Another x ray today revealed no improvement with reduction of fluid on lungs and a drop in saturated oxygen was observed. Doctors have put her back on oxygen and told me another week to clear. This seems a very long time for TTN to be a problem...? What else could be issue?  <response>: Hello dearWelcome to Chat Doctor.come have evaluated your query thoroughly. There are different reasons for the same - Infection of the lung either bacterial or viral - Birth time aspiration of amniotic fluid - Other immunity related issues of the lungs. Needs detailed case evaluation, certain lab tests and close observation to the progress of the para meters in the intensive care unit. Have to keep patience, it will take time for sure. Hope this will help you. Welcome for further assistance. Regards.
