Low Lung Volumes
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
Respiratory volumes: Tidal volume is the amount of air you inspire (bring in) with a normal breath. Usually around 500ml. Inspiratory reserve volume is the max amount you can suck in after a normal inspiration. Expiratory reserve volume is the max amount you can push out after a normal expiration. Vital capacity is the most air you can breathe out after taking the deepest breath in. ...Read more
Pft shows high dlco and frc, normal volumes, mild obstructive ventilatory defect, increased capillary blood volumes, in context of ctd and cryofibrinogenemia (no asthma or smoking), what can be cause?
Unrelated: Ctd is usually associated with a diffusion problem in the lung but your showed above normal dlco. The study also showed mild airway obstruction which, along with the elevated dlco and FRC may well be from asthma. I am not away of any cryofibrinogenemia link to your lung function findings. See an allergist or pulmonologist. ...Read moreSee 1 more doctor answer
Prognosis for untreated stage 3b non small cell lung cancer with low oxygen sats, diabetes, heart disease, high blood pressure, and emphysema.
What would cause on lung function tests, DLCO 60-75%, increased TLC and narrowing of air tubes? Finger o2 monitor 90%. Heart is fine, NAD on chest ct
See below: It would be difficult to say without all the numbers. But, if your TLC is high, then that's an indication of hyperinflation, which goes along with COPD. So does the decreased DLCO. But again, this is just generalities; would be glad to review all you results with you if needed. ...Read moreSee 1 more doctor answer
Scarring: As the lungs scar and lose volume, both the vital capacity and residual lung volume decrease. That is the nature of restrictive lung disease. ...Read more
Low sodium&fatigue&muscle loss 1year.CT scan was clear in feb16.testosterone low cortisol high. Could this be small cell lung cancer missed by CT?
Lo Na, testosterone: CT scan is fairly accurate.Testosterone can be low with age . Liver issues can cause low sodium low testosterone muscle wasting and fatigue. The fatigue can be from the low sodium. Cortisol may appear high due to low protein binding. Kidney disease can also affect sodium balance., as can thyroid disease. Drinking too much pure water is also a cause as is dehydration-Would f/u/ w/ endocrinology ...Read more
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
Spirometry results essentially normal spirometry. Hyperinflation questionable the single breath diffusing capacity is moderately impaired. COPD?
Possible: A reduced DLCO/Va points to damage or scarring in the lung tissue and emphysema (especially if you have been a smoker) or other interstitial lung diseases may be the cause. The normal lung function however is not compatible with COPD but then I don't understand what you meant by hyperinflation in the presence of normal lung function test. See a pulmonologist. ...Read more
Need to find out why: During a pulmonary function test, there are typically three measurements taken. First, how well the air "moves" in and out of the lungs. Copd, asthma, bronchitis, etc are things that would cause it to drop. Second, the efficiency of oxygen transfer is measured, the diffusion. Last, the lung sizes are measured. Again, which value is down and why its down is the most important thing to find. ...Read more
Delivery: Perspective is that 21% is the concentration from the air we breath. 2-3% increase in concentration is from each liter of oxygen added. So 1 liter is about 24% and this can go through a nasal canula tube. Over 4-5 liters, you cannot get this from a canula and need continuous flow to maintain the concentration. This would be considered "high" in my book. Not sure if this answers your question. ...Read moreSee 1 more doctor answer

Chest xray: hyperinflation of lung fields with relative peripheral oligaemic lung fields.Features in keeping with emphysematous change. Pls explain?
Xray report diffuse reticular shadowing throughout both lungs with reduced lung volumes also the right side No large pleural effusion or pneumothorax.
