How can you prevent the pulmonary deceise?
* stop smoking * stop working in a coal mine * stop using asbestos
What is an important blood buffer produced from carbon dioxide?
I need to know the important blood buffer produced from carbon dioxide.
What does mosaic attenuation mean in medical terms?
Mosaic attenuation describes a certain kind of visual pattern seen on a CAT scan of the lung. It has no diagnostic meaning - it just describes the picture.
What is the relationship between venous thrombosis and pulmonary emboli?
'venous thrombosis' is a blood clot in a vein. Sometimes these blood clots can break off from where there are and travel 'embolize' to the lung 'pulmonary'. When the blood clot travels to the lung, it will get stuck in an vessel in the lung and block flow in that branch of the blood vessel. In some medical studies, as many as 40% of people with blood clots in their legs or pelvis will have a PE, or pulmonary embolis. These are often small and go un-noticed. Unfortunately they can also be very serious and even lead to death.
What is a sedimentation rate-westergren test?
Erythrocytes sedimentation rate (ESR), Westergren method,(Sed Rate) is blood test measures how quickly red blood cells (erythrocytes) settle in a test tube. The more red cells that fall to the bottom of a special test tube in one hour, the higher the sed rate.
When inflammation is present in the body, certain proteins cause red blood cells to stick together and fall more quickly than normal to the bottom of the tube. These proteins are produced by the liver and the immune system under many abnormal conditions, such as an infection, an autoimmune disease, and cancer. There are many possible causes of an elevated sedimentation rate. For this reason, a sed rate blood test is done with other tests to confirm a diagnosis. Once a sed rate blood test is conducted, the course of the disease or the effectiveness of treatment can be monitored.
The normal sedimentation rate (Westergren method) for males is 0-15 millimeters per hour, and for females is 0-20 millimeters per hour. The sedimentation rate can be slightly more elevated in the elderly and is much lower for children.
Pulmonary edema shortness of breath and fatigue are most likely to result from?
left-sided congestive heart failure
What are the effects of sustained low blood oxygen levels?
Low blood oxygen is a condition known as hypoxemia. The effects (symptoms) of hypoxemia differ, depending on how large the blood oxygen deficit is.
Generally with mild hypoxemia, the person will feel disoriented and confused.
In more severe cases the persons skin will appear to have a bluish hue (cyanosis) and they will have a heart rate greater than normal (tachycardia).
In the most severe cases, hypoxemia can lead to coma, cardiac arrest, and death.
They should not have drawn blood on the arm to which you had a hepain going for this simple reason. Heparin is a blood thinner, which prevents proper clotting of blood; in combination with a puncture from blood draw you would get quite a blue arm, but no worries, as long as that is all that there is it will go away in a weeks's time.
Well, first there is no such thing as mls. It is mL.
Does pushing out air count as breathing?
Breathing includes drawing air into the lungs, and then expelling it, or pushing it out. These processes are also known as inhaling and exhaling.
What is manual artificial respiration?
Artificial respiration is the act of assisting or stimulating respiration, a metabolic process referring to the overall exchange of gases in the body by pulmonary ventilation, external respiration, and internal respiration. In the field of manual artificial respiration, a general crystallization of ideas occurred several years ago as a result of extensive research on adult human subjects.
What is a lower lobe pulmonary nodule?
It can be many tings : fibrosis calcified nodule (to the local old lesion - tuberculosis, dust intake to the workplace ), cancer, active tuberculosis, autoimmune disease, and more.
The differentiation can be made on radiography, MRI, microscopic examination from biopsy fragment.
What drug classes or individual drugs could cause pulmonary fibrosis?
alcohol,amiodarone,isoniazide,chlorpromazine,methotrexate,tolbutamide,copper,iron
What are characteristics of emphysema?
- Emphysema is defined as a lung disorder resulting in reduction of the lungs' ability of expelling air. This function of the lung depends heavily on the elastic qualities or rubber-band like nature of our lungs. A person develops emphysema when the tiny airways or bronchioles of his lungs get damaged. The bronchioles remain joined with the alveoli or the grape-like structures present in the sacs of our lungs. Alveoli are the site of exchange between oxygen taken from air and carbon dioxide emitted from our body. Elastic qualities of our lungs reside within the tissues surrounding the alveoli. Some characteristics of the emphysema include Due to decrease in elasticity of the lungs, the lungs cannot contract as ably as before
- Impaired lung contraction stops our alveoli from shrinking completely; this makes exhaling difficult for the patient.
- As the patient cannot exhale properly, his next breath starts with some air in his lungs.
- Presence of the old air does not allow the alveoli to take in enough amount of fresh air and this hampers the oxygen supply procedure to our body.
- Emphysema patients might experience shortness of breath as a result of exertion; with progression of the disease the patient might also develop the symptom while resting.
Why would pulmonary arteries be relatively small at the fetal stage of development?
The pulmonary artery is the artery that takes blood to the lungs to get oxygen. Because the fetus doesn't breathe, but rather gains oxygen from its mother, it doesn't need this artery as much, and so it doesn't develop as fast, so that more of the energy used for growth can be put where it's needed.
Is a head cold the same as emphysema?
No. A "head cold" is what some people call the "common cold" when it is presenting with mostly sinus and upper respiratory symptoms instead of with cough and more lung symptoms. Emphysema is a chronic obstructive lung disease also called COPD (chronic obstructive pulmonary disease) that is caused by smoke inhalation, cigarette smoking, pollution, and other damage to the lung tissue.
