Normal Lungs Vs Pneumonia
Lung capacity/asthma: Total lung capacity is the volume of air in the lungs at the end of maximal inspiration. Asthmatics can have higher lung volumes than normal people because their lungs become hyperinflated when they have attacks. They have trouble breathing all the way out, so the volume left over afterward, the residual lung volume, is also elevated. In severe asthmatics, fibrosis/scars can decrease volumes. ...Read moreSee 2 more doctor answers
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
Thin ex smoker 28yo shows hyperinflated lungs in X-ray would it indicate asthma or copd?12 pack year history. Fev values normal.odds of emphysema?
Difficult todiagnose: A chest Xray alone cannot give detailed information about whether a patient has asthma vs. COPD. Many factors must be taken into account. A full set of pulmonary function testing in a physician's office with FEV1, FVC, DLCO etc. and a detailed history and physical examination is the first step. ...Read more
Chesty cough>6wk,X-ray show lung well expanded no collapse/consolidation.licency of lung marking within both upper lobes.is it serious?clear phlegm.
37 wks preg. CT scan of lungs ruled out oulmonary embolism but showed minor dependency change and atelectasis. suggested air trapping. is this concern?
What they: are calling dependent changes are usually normal and simply related to the effect of gravity on your lungs when you lay on your back. "Air trapping" relates to retention of excess air in the lungs or parts of the lungs. The CT findings of air trapping can be seen in normal individuals, but also in asthma, chronic bronchitis, and other entities, so talk to your doc about the results. ...Read moreSee 1 more doctor answer
Chest X-ray Hyperinflamed lung and perihilar bronchitis changes are seen.No acute pulmonary or pleural disease.25 year,non smoker,Please explain findi?
Might be normal: I obviously have to make some assumptions without seeing the films myself. First, I believe that "hyperinflated" was meant instead of hyperinflamed, as it is a more common term. It is used often when lungs appear over expanded.Although it sometimes suggests air trapping seen in asthma, or copd... It tends to be overused...and is often seen in normal people who are able to take a very Deep breath ...Read more
Lung Cavity Causes: Not at all! differential DX of cavitation on chest x-ray: 1 caveating pneumonia: s aureus, gram-negative bacilli (klebsiella, pseudomonas, legionella), anaerobes, mycobacteria, fungi, pneumocystis. 2 septic emboli, bacterial or fungal. 3 wegener's granulomatosis or pulmonary infarction 4 infected bullae or cysts. 5 cancer: primary or secondary. Clearly, your doctor will help sort these out. ...Read moreSee 2 more doctor answers
CT angio: of the chest is usually diagnostic for pulmonary embolism. Analysis of the pleural fluid, including mycobacterium cultures would point toward tuberculosis, which otherwise may be difficult to diagnose, unless living in an endemic area. Beware that the 2 conditions may coexist, unfortunately, and having 1 does not rule out the other. ...Read more
COPD: The simple answer is YES! However, I don't understand why your specialist is not treating you better! Please let me know how things go. ...Read more
Lung CT scan shows no inflammation no scarring pulmonary pft shows decreased gas exchange heart fine positive ana. What could cause sob?
Definitions...: "walking" pneumonia is slang terminology that refers to a situation where there is an infiltrate on chest x-ray but the person has few symptoms. There are different scenerios that can produce this situation. "asthmatic bronchitis" means that there is bronchospasm associated with bronchitis, an infection of the airways. It can sometimes lead to a cough as the infection is resolving. ...Read moreSee 1 more doctor answer
LEFT UPPER LUNG OPACITIES. CONCIDER INFECTIOUS PROCESS SUCH AS PNEUMONIA OR PTB OF UNDETERMINED ACTIVITY VERSUS FIBROTIC CHANGES, means?
Clinical history: So it depends on prior exposures. If you clinically have cough, fever, mucus production more likely an acute infection like pneumonia. However in endemic area, tuberculosis until proven otherwise. In younger person without other lung issues it would be rare to have fibrosis in upper lungs. See specialist if this does not resolve with antibiotics and repeat xray (priors?) for help ...Read more
Xray result:Prominent perihilar interstitial markings suggesting bronchitis.No superimposed infiltrate or atelectasis.I thought bronchitis didn't show?
Subtile finding: Normal bronchial walls are hard to see on a chest x ray (arrows in pic). If they are thickened one can see them a little more. Even so, it is a tough call so we say "suggestive of" to say we really are not sure, but we see enough to be more than just a little suspicious. For complete eval of lung tissue we do high resolution CT. "Bronchitis" is a clinical diagnosis, though, so listen to your Dr. ...Read more
Can interstitial lung disease like pulmonary fibrosis and those like pulmonary fib. Be ruled out pretty good with pulse ox, CT of lungs, and chest xra?
Would lung cancer cause enlarged hilar and mediasternal nodes, GGO on Chest CT and impaired gas exchange. Other lung function tests are normal?
Possibly: There are many different forms of lung cancer however the most common types usually appear as a solitary nodule or mass on CT. GGO can be seen with lymphatic involvement as is suggested by the enlarged lymph nodes described. This can be from infection, cancer or autoimmune diseases such as sarcoidosis and even heart failure. A biopsy of an enlarged lymph node may be required. ...Read more
Pneumonia : Acute inflammation of the walls of the smaller bronchial tubes, with irregular areas of consolidation due to spread of the inflammation into the peribronchiolar alveoli and the alveolar ducts of the lungs. Also called bronchial pneumonia. Lobar pneumonia - pneumonia affecting one or more lobes of the lung; generally lobar is larger and affects one or more loves of the lung. ...Read more
