What effects could pneumonia and pulmonary congestion have on gas exchange?

Both pneumonia (infectious inflammation of the lungs) and pulmonary congestion (left heart failure) can lead to fluid accumulation in the lungs.

Pneumonia and pulmonary congestion cause a fundamental change in the way gas is exchanged within the lungs. Gas is exchanged through structures called alveoli. They are microscopic sacs of epithelial tissue. When these sacs become filled with fluid (referred to as consildation) gas cannot pass from the alveoli into the blood. Thus, gas exchange is impeded and the patient typically must work harder to breathe.  (+ info)

What is involved in a typical pulmonary function test?

I have to get a typical pulmonary function test tomorrow. What exactly does this entail? I looked online and didn't find anything that really explained it. I'm 15, if age makes any difference. Thanks!

In a spirometry test, you breathe into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that you breathe in and out over a period of time.  (+ info)

How does pregnancy increase the risk of pulmonary and other emboli?

How is pregnancy associated with an increased risk in pulmonary embolism? Does this explain the association between long term use of oral contraceptives and thrombosis, which could possibly lead to embolism?

Yes and no. The hormones that are increased in pregnancy and contained in the contraceptive Pill aren't the only risk factors for blot clots forming during pregnancy. What the Pill and pregnancy both have in common is that they both produce hormones that increase the bloods clotting ability. Oestrogen increases the risk of DVTs by increasing the production of certain chemicals necessary for the blood to clot. It also increases platelet numbers + stickiness of platelets, which increases clot formation (to prepare for blood loss during child birth). Progestogen in the Pill causes the blood vessels to relax and widen, allowing the blood to pool in the veins, increasing risk of clot formation.

Blood clots in pregnancy are generally the result of increased venous stasis- blood pooling in the lower deep veins. As I said above, balance of proteins of the coagulation + fibrinolytic systems also play a part. DVT can of course lead to a pulmonary embolism. Clots in pregnancy and from the Pill are generally always the results of clots that have formed in the deep veins of the legs, broken away and then embolised in the lungs.

Women who do have clots in pregnancy and whilst taking the contraceptive Pill, generally also have certain other risk factors such as protein C and S deficiency and most commonly Factor V Leiden mutation. Over all health of the woman also plays a part- obesity, poor diet/unhealthy lifestyle and a smoking history also increases the risk as does age.

During pregnancy the uterus also expands, putting pressure on the lower blood vessels which can restrict blood flow from the legs and pelvis back to the heart. Physiological structural changes during pregnancy are risk factors alone.  (+ info)

What are the multidisciplinary team responsibilities for the patient suffering a pulmonary contusion?

I have a case scenario which I am writing an assignment on. (Pulmonary contusion and Acute Respiratory Failure) part of this assignment requires me to discuss the multidisciplinary roles. The info on this is not very clear, I recognise there are roles played by the physiotherapist and nurse also the physician and have a general idea of what they are but need confirmation, Can anyone help?

let the nurses do everythng, cause they are the know-it-alls of the medical field.  (+ info)

What is unique about blood in pulmonary arteries compared with blood in other arteries?

a. It is loaded with carbon dioxide.
b. It is moving toward the heart.
c. Blood in pulmonary arteries is always blue; it is red in all other arteries.
d. It is the same as blood in other arteries.
e. It is moving away from the heart.

A and C...but if you had to choose go with A  (+ info)

What is the difference between asbestosis and pulmonary fibrosis?

My husband has been advised by his consultant to claim industrial disease allowance for his pulmonary fibrosis.Has he worked in shipbuilding with asbestos we expected to be told he had asbestosis!Should we be pleased or is it two names for same illness? He has lost a lot of former colleagues to asbestosis and so we and especially me, are very concerned about his quality of life in the near future.

asbestosis is caused by exposure to asbestos asbestos fibres are thin and microscopic and easily pass through the filters in the nose and bronchi into the lungs it sticks to the lungs and scars the lung tissue it makes it harder for the lungs to function properly and gas exchange gas exchange in the lungs gets harder it can cause respiratory failure and can take years to develop
pulmonary fibrosis scars the tissue in the lungs eventually the air sacs in the lungs are all replaced by fibre or scar tissue this tissue is thicker and the tissuyes cant transfer oxygen to the blood anymore  (+ info)

What is bilateral pulmonary disease and what causes it?

Recently a friend became ill and everyone including her felt it may be flu as it is flu season. But, she complained of shortness of breath and had to be given oxygen. Later she had the problem again and had to be given oxygen. It is said that she had a bag full of fluid removed from around her heart and mucus started to solidify in her lungs.Diagnosis was bilateral pulmonary disease which few people have heard about or understand except that it affected her breathing. What causes such a disease? Could the aircondition in an office be a factor?

When is it safe to travel after a pulmonary embolism?

A friend visiting from Europe developed a pulmonary embolism after a surgery. She has been started on a blood thinner. When is it safe for her to fly back home?

Never. She needs to become an American citizen and stay here forever. Or at least take a boat home and not a plane. LOL  (+ info)

How long after the initial symptoms would a pulmonary embolism cause serious problems?

I am doing an essay on 'sudden death' (cheerful, eh?) and am looking for info on pulmonary embolisms / infarction

Could anyone tell me how long after initial symptoms (pleuritic chest pain / cough etc) someone wouyld expect to go before hospitalisation is required ? Do PEs come on over time or are they sudden ???

A Pulmonary Embolism would cause immediate problems. Depending on the type of emboli. How about this:
At 2:01 pm a person throws a PE to the lung:
1. Short of Breath
2. O2 Saturation Drops
3. Unable to get oxygen into the system
4. Hypoxiema
5. Tachycardia
6. Someone had better dial 911 or this person is going to be shaking hands with St. Peter.

Time 2:10

7. Cardiac Arrest

All right sometimes it is not that dramatic. But on Sunday, I had a patient do just that. Lucky for us he was already on life support and we were able to treat. So sometimes it does go that fast and sometimes it depends on just a lot of other things like:

Is the person previously healthy with no lung disease? Then they have a better chance than someone who has extensive lung disease.

What is the person's age? Why did they throw the PE? All of these things come into play.  (+ info)

What kind of diseases or symptoms does a pulmonary disease doctor treat?

How do I know if I should see a pulmonary doctor for my symptoms?

Respiratory diseases, diseases of the lungs. Such as asthma, emphysema, etc.  (+ info)
