How Can Emphysema Reduce The Amount Of Oxygen That Diffuses Into The Blood
Destroys the lung: Emphysema causes destruction of lung tissue. The blood vessles in the lung get destroyed in the lung. These vessles carry the blood in the lung to pick up oxygen. If they are destroyed then, oxygen can not get into the blood vessles / blood and you get low oxygen. ...Read moreSee 1 more doctor answer
COPD may include chronic bronchitis, emphysema, or both. Chronic bronchitis is the production of increased mucus caused by inflammation. Bronchitis is considered chronic if you cough and produce excess mucus most days for three months in a year, two years in a row. Emphysema is a disease that damages the air sacs and/or the smallest breathing tubes in the lungs. ...Read more
From Destruction: The destruction in the lung tissue from emphysema makes the oxygen harder to cross into the blood because there is less tissue surface left. With less air sacs to participate in gas exchange, it is harder for oxygen to cross into the blood. Does that make sense? That's why people should stop smoking. ...Read moreSee 1 more doctor answer

Not usually: In the late stages of emphysema or copd, patients do not respond normally to stimuli that make normal patients breathe. They only keep breathing in response to low oxygen in their bloodstreams. If they are given too much oxygen, their systems think that they don't need to breathe and they can actually breathe less or stop breathing. This is a rare problem. Oxygen helps most emphysema patients. ...Read moreSee 2 more doctor answers
Prognosis for untreated stage 3b non small cell lung cancer with low oxygen sats, diabetes, heart disease, high blood pressure, and emphysema.
Yes and No: Patients with emphysema are at some risk for developing high carbon dioxide levels (hypercapnea) if given high doses of oxygen. The oxygen will displace the carbon dioxide off of the red blood cell resulting in higher blood levels (haldane effect). However, hypoxia (low oxygen) is more likely to kill a patient than hypercapnea (high co2) so using high dose oxygen may be needed. ...Read moreSee 1 more doctor answer
O2 is good.: Long term oxygen therapy has been shown in some trials to improve mortality. It has also been shown in other trials to improve quality of life, reduce depression, improve cognitive function, improve exercise capacity, and reduce frequency of hospitalization. ...Read moreSee 2 more doctor answers
Emphysema is also known as COPD. Emphysema is a lung disease caused by destruction of lung tissue--specifically the alveoli, which are the smallest sac-like units of the lung responsible for oxygen exchange. It is characterized by shortness of breath, an expanded chest, and possible signs of low oxygen in the body such as bluish ...Read more
