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
Depends: As noted, one time exposure to heavy smoke is not likely to result in pneumothorax. The risk factors for primary and secondary spontaneous pneumothorax (sp) include: smoking (including marijuana), tall thin stature in otherwise healthy, connective tissue disorders, pregnancy, familial history. Lung inflammation is hypothesized to play an important role in the lung injury process that predispose. ...Read moreSee 1 more doctor answer

How does it really feel when you get a part of your lung removed from a thoracotomy procedure due to pneumothorax? Do you feel short of breath?
Depends: It depends on the size of the clot and how much it affects blood flow, as well as how much reserve you have. I've seen cancer patients that were otherwise healthy with massive clots, detected incidentally on a screening ct - otherwise, felt fine. On the other hand, i've seen small clots that have laid elderly patients low. ...Read more

Define air capacity: If by air capacity, you mean your lungs vital capacity, then no. Your vital capacity is dictated by your anatomy (it's a function of your age and height). But if you're referring to your vo2max (maximal aerobic capacity) then yes, since this is a measure of oxygen use and indirectly, physical fitness. ...Read more
Many things: There are many causes of shortness of breath. The easiest way is to compartmentalize into three categories. 1. Any problems with the heart – heart failure, enlargement of the heart, or valve disease of the heart. 2. Any problem with the lungs – asthma, COPD, fluid around the lungs, fluid in the lungs, or lung scarring to name a few. 3. Everything else – deconditioning or knee/hip pain for example. ...Read more

Yes....: A collapsed lung, or pneumothorax, occurs when air leaks into the space surrounding the lung, between the lung and chest wall. If enough air acummulates in this space, there can be enough pressure to push vital structures, including the heart, to the opposite side of the chest. This tension pneumothorax can lead to cardiac arrest which can result in death if not immediately treated/resuscitated. ...Read moreSee 1 more doctor answer
