Doctor insights on: Damaged Lungs Pneumonia Low Oxgen

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

I recently had a ct scan with contrast. It said I had some linear scarring in lower left lung. Everything else looked ok. I had a small granuloma on a previous scan same area. I had pneumonia in that area a year ago. I have great oxygen. That was all that

I recently had a ct scan with contrast. It said I had some linear scarring in lower left lung. Everything else looked ok. I had a small granuloma on a previous scan same area. I had pneumonia in that area a year ago. I have great oxygen. That was all that

That was like you..: ..said, scarring due to pneumonia in the past. If you don't have any symptoms of fever, cough, sputum, shortness of breath, sweating or weakness, then you most likely don't have pneumonia. And a granuloma would not be anything to lose sleep over. Size and all. I would continue to monitor the situation from a distance. ...Read more

My father has been in the hospital for 7 days now. He has stage 4 lung cancer, COPD, and pneumonia. Oxygen saturation at 89 at rest, 75 standing. Bad?

My father has been in the hospital for 7 days now. He has stage 4 lung cancer, COPD, and pneumonia. Oxygen saturation at 89 at rest, 75 standing. Bad?

Neither bad nor good: Getting lung cancer means getting a finite view of the remainder of one's life... it changes things. With end stage lung cancer, there is neither good nor bad. Things will play out as they always do, and the goal is a relaxed comfortable exit when the time comes (an exact time is not predictable). Larger hospitals have Palliative Care specialists who can help, as they help such patients every day. ...Read more

Two clear X-rays after right lowerlobe pneumonia and atelectasis. Still pain in that right lung daily and low grade fever for over 1 month. What now?

Two clear X-rays after right lowerlobe pneumonia and atelectasis. Still pain in that right lung daily and low grade fever for over 1 month. What now?

Atelectasis....: Atelectasis, which is when there is collapse of the small airways in the lungs, could account for your symptoms. If you get an incentive spirometer, and use it every hour while awake, the atelectasis will resolve faster. So, see your doctor and get an incentive spirometer. Your doctor can show you how to use it! And, if you smoke, you need to quit ASAP to decrease airway inflammation. ...Read more

My mom is being hospitalized for pneumonia and a possible blood clot or COPD I'm very worried could it be deadly her oxygen and blood pressure is low?

Unanswerable: There are just too many unknowns here. I am very sorry to hear of your mother's troubles, but it sounds like she is in the right place and getting the right attention. In these scary scenarios this kind of answer must come from the medical team working with her in person. ...Read more

If something is wrong with my lung or lungs will my oxygen generally be low?

See your doctor and ask for a more complete explanation of your functional status and whether or not there are other diseases affecting your blood oxygen level. ...Read more

What can cause low oxygen? When they were checking mine I had an 89 and they said that was low. Don't have heart or lung problems, did skip breakfast.

What can cause low oxygen? When they were checking mine I had an 89 and they said that was low. Don't have heart or lung problems, did skip breakfast.

Many causes: Hi
The first thing I would do is make sure the test was reliable but 89 is incredibly low. If you physically feel fine and it was truly 89, then you may have an undiagnosed medical condition because it means that your body is compensating to some degree. But, at 89%, your body can't compensate for long and will wear down eventually. Make sure to keep your follow up appointments. Hope this helps ...Read more

I had pneumonia 3 weeks ago and now have sinusitis. On amox for 2 days no improvement, and a low grade fever. Could it be the pneumonia reoccurring? Should I get another chest x-ray?

I had pneumonia 3 weeks ago and now have sinusitis. On amox for 2 days no improvement, and a low grade fever. Could it be the pneumonia reoccurring? Should I get another chest x-ray?

May not be pneumonia: If you are an otherwsie healthy patient the liklhood that you would have recurrent infection with the sam bacteria is not lilely. More likely is that you have an ellemnt of allergies or possibly asthma that predispose to prolonged and recurrent episodes of congestion. Certainly if you feel short of breath or are coughing, a repeat visit to the doctor is in order. ...Read more

Nonspecific: Can suggest an enlarged liver, reduced volume in that lung, an incomplete inspiration, etc........By itself, even with your history, does not add much / point to a clear answer. Likely chest wall (musculoskeletal) or pleuritic given your age. Nsaid for few days should reduce and/or eliminate symptoms. If not, should follow up with primary doc for further evaluation. ...Read more
