When pulmonary embolism happens in the lungs, what makes it so fatal?

When pulmonary embolism happens in the lungs, what makes it so fatal?

Several things: A massive pulmonary embolus will essentially block most of the blood flow from the right ventricle to the lungs, preventing blood from getting oxygenated while putting a huge strain on the right ventricle. Since blood is then blocked from getting to the left side of the heart, systemic blood pressure severely drops along with oxygen delivery and things rapidly go down the tubes. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

When pulmonary embolism happens in the lungs, what is actually going on?

PE: Clot traveled from somewhere to the right atrium and if able to the right ventricle, outside to the arteries of the lungs and cause blockade of flow as they go to the arteries wherein the size of the clot can't go through. ...Read more

I had a pulmonary embolism & a pulmonary infarct 1 1/2 years ago. Can i go into the sauna 2x a week or is the sauna not good for my lungs?

I had a pulmonary embolism & a pulmonary infarct 1 1/2 years ago. Can i go into the sauna 2x a week or is the sauna not good for my lungs?

Depends: If your pulmonary embolism/infarct didn't compromise your heart or lung function than unless you have another medical condition that would complicate your being in a sauna, it shouldn't be a significant problem. If you are really concerned you should contact your primary care physician. Otherwise if you do decide to go forth, if you have any shortness of breath or lightheadedness please leave! ...Read more

What to do if i recently had a chest X-ray to look at my lungs. Would a pulmonary embolism have shown up?

Unlikely: There are some secondary x-ray signs but usually ct scan or v/q scans are necessary to detect pulmonary clots. Plain chest x-ray can suggest an area with decreased lung markings, density of infarct, or peripheral lung contour abnormalities. ...Read more

Is pulmonary embolism an obstruction in the main artery to the lung?

Is pulmonary embolism an obstruction in the main artery to the lung?

Any artery: A pulmonary embolism (pe) is a clot in any of the arteries in the lungs. If the clot is large, it will lodge in one of the larger arteries, and can be fatal. If the clot is smaller, it will travel into the lung until the vessel is small enough to trap it, and may not even cause much in the way of symptoms. Any pe is serious, and the source of the clot needs to be found to prevent recurrences. ...Read more

What are the warning signs of a pulmonary embolism (pe or blood clot in the lung)?

What are the warning signs of a pulmonary embolism (pe or blood clot in the lung)?

Various: The usual warning signs of a pulmonary embolism (pe) include tachycardia (fast heart rate), dyspnea (shortness of breath), chest pain which can be pleuritic (ie hurts when you take a deep breath), fainting (known as syncope) and cyanosis (blue discoloration of the lips or nailbeds). ...Read more

What is the difference between septic embolisms in the lungs and a pulmonary embolism?

What is the difference between septic embolisms in the lungs and a pulmonary embolism?

Bacteria: Emboli are stuff (most commonly clots) that move from somewhere to somewhere else down a blood vessel, in this case from clots in veins of the body, down to the heart, and through its right side to the lungs, where they can block blood flow to these organs. Septic emboli are stuff that also has bacteria inside, and therefore can cause further infection in the lungs, and even greater damage. ...Read more

I have high lung pressure after pulmonary embolism, could I have pulmonary hypertension now?

I have high lung pressure after  pulmonary embolism, could I have pulmonary hypertension now?

PE and PH: While it is an uncommon condition, what you describe is certainly possible. Pulmonary hypertension (ph) is abnormally high blood pressure in the arteries of the lungs which can be caused by pulmonary embolism (pe) or blood clots that do not adequately resolve. ...Read more

After having a pulmonary embolism and taking warfarin, how long and how do they ttest to see if the clot has desolved in the lung?

After having a pulmonary embolism and taking warfarin, how long and how do they ttest to see if the clot has desolved in the lung?

Not useful: It is not useful to repeat testing, for most patients. Your body will remove the clot. The medication is used to make sure you do not get a new clot. Most important is to be followed by a lung doc who has expertise in lung clots. ...Read more

I had a pulmonary embolism in march 2012 and was intubated in icu...I continue to have tightness in my lungs upon deep breathing and pain in my back.

See a physician: After 1 year scar tissue may have developed or the original disease process needs t o be checked. See your physician and they probably will order a followup chest xray. ...Read more

I had 9 emboli's in my left lung. had all symptoms of a pulmonary embolism. I was later told that I had pneumonia. I was never sick nor had a fever.

I had 9 emboli's in my left lung. had all symptoms of a pulmonary embolism.  I was later told that I had pneumonia. I was never sick nor had a fever.

Occam's razor : If you were diagnosed with multiple pulmonary emboli (CT scan with PE protocol), it isn't unusual to develop pulmonary parenchymal changes and even pleural effusion. The emboli are causing lack of blood supply to the parenchyma and causing tissue death and a release of infammatory markers. Sometimes the changes can be construed as infection when not. Occam's razor applies. ...Read more

Will my mom, who has lung cancer, have a higher chance of getting a pulmonary embolism on a flight?

Will my mom, who has lung cancer, have a higher chance of getting a pulmonary embolism on a flight?

Yes: Patients with cancer are at a greater risk of developing blood clots. Ask your doctor about compression stockings that may reduce the risk clots in the legs. Also, i recommend to get up at least once an hour to walk around the plane. ...Read more

Any ideas why heart failures come from pulmonary embolism in the right upper lobe of the lung in arteriosclerosis?

Any ideas why heart failures come from pulmonary embolism in the right upper lobe of the lung in arteriosclerosis?

Several ways: The pe can cause low oxygen including what goes to the heart. It can put strain on the heart, dilate the right side, cause hormones to be released cause tachycardia and due to that chf, arrhythmia and failure of the heart to push blood if big enough. It can then cause paradoxical pressures in the ventricles collapsing the left ventricle due to right pressure. ...Read more

Will a CT scan of chest/lungs w/o contrast still show pulmonary embolism and what r my options for treatment? Will I be able to breathe better again?

Need CT angiogram: You really need a CT angiogram of the chest to reliably detect pulmonary embolism. IV contrast is needed to see blood clots in the pulmonary vessels. Anticoagulation is the main treatment for pulmonary embolism. ...Read more

Usually a blood clot that migrates from one area of the body to another. Most commonly a clot from a leg vein to the lung . It can also pertain to a clot, or atheromatous material that moves from one segment to another, such as cholesterol material in a carotid lesion moving into the ...Read more
