How can emphysema reduce the amount of oxygen that diffuses into the blood ?

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 more

Copd (Definition)

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

How does emphysema reduce the amount of oxygen which diffuses into the blood?

How does emphysema reduce the amount of oxygen which diffuses into the blood?

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 more

How does hyperpnea affect the amount of carbon dioxide and oxygen in the blood?

How does hyperpnea affect the amount of carbon dioxide and oxygen in the blood?

Low CO2, alkalemia: Deep or rapid breathing removes more gaseous co2 leading to less co2 in the blood and associated alkalemia - it has a minimal effect on oxygenation except in disease states. ...Read more

Does midodrine reduce amount of blood flow in the lungs at all?

Does midodrine reduce amount of blood flow in the lungs at all?

Midodrine: Midodrine is an Alpha agonist but has relatively little data compared to most other approved drugs. It shouldn't reduce pulmonary blood flow but i can't find data to prove that. ...Read more

What will increase the partial pressure of oxygen in lung alveoli?

What will increase the partial pressure of oxygen in lung alveoli?

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

Can you tell me how the prescence of carbon dioxide reduce the affinity of heamoglobin for oxygen?

Can you tell me how the prescence of carbon dioxide reduce the affinity of heamoglobin for oxygen?

Bohr effect: Any physiology textbook will explain this to you. The shape of the hemoglobin molecule is changed slightly. It's a good thing that it gives up its oxygen more easily when there's a lot of carbon dioxide / low pH, as that's a sign that oxygen might be needed in the area. ...Read more

How does oxygen carried in the blood reach the other cells?

How does oxygen carried in the blood reach the other cells?

Red blood cells: Your red blood cells carry oxygen to your body. Red blood cells are packed with an iron containing protein called hemoglobin that can bind oxygen in your lungs and carry it to every cell in your body. In the tissues, oxygen leaves hemoglobin in part because of the acidic environment, called the Bohr effect, and carbon dioxide is bound by hemoglobin to carry to the lungs where you breathe it out ...Read more

Is it true that a build-up of fluid in the lungs will result in a reduced amount of oxygen in the blood returning to the heart?

Is it true that a build-up of fluid in the lungs will result in a reduced amount of oxygen in the blood returning to the heart?

If Bad Enough: The lungs have remarkable capacity to overcome problems with what we'd call "gas exchange", but if enough of the lung tissue is taken out of the picture (eg by being covered in fluid) then yes, the amount of oxygen brought back to the heart will definitely fall. ...Read more

What effect does exercise have on the amount of carbon dioxide released by the blood?

Respiration: When you exercise multiple physiological processes occur. You metabolize more thus producing more co2. Co2 is scrubbed from the blood by the lungs to eliminate it. Co2 is regulated very tightly and part of the issue is actually how fit you are - a cross country runner has a different co2 physiology than a couch potato or a smoker. ...Read more

How does increase amount of the carbon dioxide in the blood affect kidney and causes renal failure?

How does increase amount of the carbon dioxide in the blood affect kidney  and causes renal failure?

Carbon Dioxide : Good question. Your kidneys have many functions. One is to maintain ph balance. When your body accumulates too much carbon dioxide(co2) your kidneys work to eliminate it. Co2 makes your body more acidic. The acidity not only makes your kidneys work harder, but it also makes all body functions less efficient. Over time this can cause kidney failure. This is not a common cause of kidney failure. ...Read more

Does chronic exercisce get the body to adapt and increase the number of alveoli in the lungs?

Does chronic exercisce get the body to adapt and increase the number of alveoli in the lungs?

No : You don't get more alveoli with exercise. But your heart gets in better shape, your muscles get stronger and more efficient at using energy. That's why exercise is so good for you. Keep it up! ...Read more

Will midodrine reduce the amount of blood in the brain and cause problems?

Will midodrine reduce the amount of blood in the brain and cause problems?

No: Midorine is a medication used to treat symptomatic low blood pressure which may be causing faintness. If any thing it will restore the appropriate amount of blood to brain and all other organs. ...Read more

Can heart failure cause a decrease of carbon dioxide in the blood?

Heart failure: CHF can cause a degree of acidemia. This is reflected by decreased bicarbonate (sodium bicarbonate) in the electolyte panel. This is not carbon dioxide but is related. ...Read more

How can hyperpnea affects partial pressure of carbon dioxide and oxygen levels in the blood?

How can hyperpnea affects partial pressure of carbon dioxide and oxygen levels in the blood?

Hyperpnea/tachypnea: The rapid breathing will blow out co2 and lower its level in the blood. This may or may not affect the o2 level depending on the cause of the tachypnea. ...Read more

What are the chances of a small pneumothorax healing by itself, and how would the body absorb the leaked air?

What are the chances of a small pneumothorax healing by itself, and how would the body absorb the leaked air?

Yes: If it were small, it could resolve over time. That pre-supposes that the reason for the pneumothorax has sealed over and will not expand it.The gas within just diffuses across the membranes surrounding it. ...Read more

How does the heart get oxygen if it's the organ that pumping the blood to the rest of the body?

How does the heart get oxygen if it's the organ that pumping the blood to the rest of the body?

Oxygen: Oxygenated blood leaves the pulmonary circulation and is pumped through the left side of the heart. After it goes through the aortic valve oxygenated blood flows in both systole and diastole through the coronary arteries into the heart muscle. ...Read more

Can hyperventilation cause the loss of alrge amounts of carbon dioxide from the body?

No: There is a feed back system at work. It is the co2 (carbon dioxide) levels in the blood that drive the breathing center in the brain. When you hyperventilate, you may decrease the co2 in the lungs which reduce some of the level in the blood which will then cause that breathing center to decrease the rate of breathing (hyperventilation). Ultimately hyperventilation can dec co2 only so much. ...Read more
