Why patient with emphysema thin?
Because emphysema reduce the oxygen perfusion (transfer) from alveoli into the blood thus also reduce the oxygen supply to the muscle and organ. Reduce the oxygen delivery to the periphery cause weight loss and thus they (emphysema patient) look thin.
What chemical alteration of the blood stream results from emphysema?
Emphysema causes lower oxygen levels in the blood.
How can you get more oxygen in to the blood if you have Emphysema?
people with this disease normally will have to carry an oxygen tank with them where ever they go.
What happens to blood gases in a patient with emphysema?
Decreased Oxygen, increased CO2, Acidosis
What are some reasons high carbon dioxide and low oxygen in the blood?
COPD -emphysema and chronic bronchitis
Explain how changes in the alveolar structure cause a decrease in the blood oxygen levels in emphysema?
Decrease in alveolar surface area results in less boundary across which oxygen can be absorbed into the blood.
What drug has its basic purpose to reduce the work of breathing increase oxygen content of the blood reduce the work of the heart?
oxygen
How does emphysema affect the removal of CO2 from the blood and delivery of oxygen to cells?
In emphysema there is actual breakdown of the alveoli; the tiny air sacs where oxygen and carbon dioxide are exchanged in the lungs. When they are broken down they are replaced with scar tissues and and a loss of surface area. Human lungs have an area about the size of a tennis court when all the alveoli are healthy. A person with emphysema may have only a fraction of that available area for the gas exchange to occur. That is why they end up needing a respirator, so more concentrated oxygen can enter their partially functioning lungs so that they can get enough oxygen into their blood stream.
How does smoking effect running?
Smoking can weaken the lungs and reduce breathing capacity. Also smoking can reduce oxygen level of blood thus blood can not carry enough oxygen to the necessary organ.
Explain how the changes in alveolar structure cause a decrease in blood oxygen levels in emphysema?
Pneumonia fills the lung's alveoli with fluid, keeping oxygen from reaching the bloodstream.
What can Blood gas levels diagnose?
Low oxygen and high carbon dioxide levels are often indicative of chronic bronchitis, but not always of emphysema
Why does the arterial Po2 decrease with emphysema?
emphysema is a condition of loss of elasticity of the alveoli where exchange of oxygen and Co2 occurs. The alveoli cannot efficiently exchange oxygen for Co2 so Co2 builds up in the blood. It is usually caused by chronic smoking but can be caused by other diseases/conditions.
