Increase Lung Capacity
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
It depends: The transplant center will evaluate whether based on their transplantation survival statistics and your clinical disease severity, whether the benefits outweigh the risks. The allocated organs are received first by the patients who are the most severe, and most likely to benefit from an organ transplantation. Transplantation centers will have information on this for you. I hope that this helps. ...Read moreSee 1 more doctor answer
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
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

Not direclty: Being dehydrated would not affect lung capacity in terms of spirometric testing, however,it will cause weakness similar to that due to limitation of lung capacity. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...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
Complex: The heart and lungs work together and respond to each other on many levels. Giving extra oxygen can lower a rapid heartbeat, but the fast heart rate does not necessarily increase oxygen absorption in the lungs. It depends on how fast the heart is beating, why it is beating fast, and the status of the lungs (ie diseased lungs from any cause are not as good at picking up oxygen as healthy lungs). ...Read moreSee 1 more doctor answer
Increases HR: Marijuana use increases heart rate by 20%-100%, shortly after smoking. Marijuana users have 4.8 times greater chance of heart attack in the first hour after smoking. It causes palpitations & arhythmias as well as elevation of actual heart rate. http://www.ncbi.nlm.nih.gov/pubmed/11401936. ...Read moreSee 1 more doctor answer
O2/ventilation/diet: Partial pressure of oxygen in alveoli is can be calculated using the alveolar gas equation. Oxygen level increases if there is a higher atmospheric pressure (hyperbaric chamber), higher inspired concentration of oxygen (using supplemental oxygen from a tank), lower co2 in lungs by breathing faster and deeper, raising respiratory quotient by eating more carbs, less fat. ...Read more
Yes: Several recent studies have shown that air pollution seems to contribute to an increased risk of coronary artery disease. In observational studies that correlated the degree of air pollution in various cities, there was a clear relationship between higher levels of air pollution and a higher incidence of heart disease. Very provocative recent work, but not surprising given the risk of cigarettes. ...Read moreSee 1 more doctor answer
