What is Pulmonary Embolism?


Known as blood clots in the lungs, a pulmonary embolism is one of the larger blood clots that can develop and stop blood flow to an artery in one of the lungs. These blood clots often initiate in a limb like a leg or arm and travel to the lung. Blood clots in the lungs are life-threatening and need immediate medical assistance. This can cause significant pain and shortness of breath and put the body in a dire state of emergency.


Pulmonary Embolism Symptoms 


If you aren’t sure if you have a pulmonary embolism, some symptoms will give you insight into something wrong. The common symptoms include the following:

  • Unexplained sharp pains in the back, shoulder, chest, or neck
  • Shortness of breath at any time, during rest or activeness
  • Steady wheezing
  • Bloody mucus with coughing
  • Rapid heartbeats
  • Wheezing
  • Fainting or lightheaded
  • Pale or blue-looking skin
  • Steady sweating

These signs may not all happen at once, but they will start to add up, and the longer you have the blood clot in your lung, the more symptoms you’ll develop from the pulmonary embolism. Some of these symptoms may seem minor, like excessive sweating, but if this isn’t common for you when you’re feeling well, something is wrong within the body.


PE Causes


There are a few things that can cause a pulmonary embolism, and you must think about if you’ve gone through any of these recently. Blood pooling in a certain part of your body is one of the most common reasons for these blood clots, as it is due to long periods of not being active following surgery, very long plane rides, or bed rest due to a condition. Also, if you’ve recently experienced a vein injury that was severe during surgery or a fracture, you could be at risk for developing a pulmonary embolism.

Some other causes include having a stroke or heart attack in the last few weeks, where blood pooled after a blockage. For those who have issues with blood clotting, especially following chemotherapy, there is a chance that they are at risk for a pulmonary embolism.


PE Risk Factors


Anyone who’s been diagnosed with DVT or deep vein thrombosis should be aware of blood clots in the lungs, as they are at a higher risk. Those who’ve undergone surgery recently that’s left them with extensive bed rest and vein injuries should also watch for signs of a pulmonary embolism. If you’re relatively healthy but you’ve been taking hormone replacement drugs or birth control, there could be some side effects with blood clotting and could put you at a higher risk for a pulmonary embolism. Read more about the relationship between DVT vs. Pulmonary Embolism.


Receiving a Pulmonary Embolism Diagnosis


If your healthcare professional or doctor thinks that you might have a pulmonary embolism, there are a few tests that can determine if you have one or more blood clots in your lungs.  The first test will be blood work that checks the D-dimer test for clots. Other tests will include a CT scan of your lungs to look for a blockage. If the CT scan is inconclusive, your medical team will use the VQ scan to do a nuclear scan of your lungs for a clot.

Ultrasounds are also used on your limbs to see if a blood clot is on the move to the lungs. To check the condition of your heart, they will also do an echocardiogram to make sure there isn’t any extra stress on the heart, and if there is, locate it for treatment.

When to Worry About Pulmonary Embolism


If you’ve started to experience any of the symptoms above for a couple of days, it may be a possible sign that something is wrong. You’ll need to reach out and receive medical attention right away and have your lungs checked for a blockage so that you can begin treatment.

Preventing a Pulmonary Embolism


If you’ve experienced a recent surgery, a long plane ride, or gone through chemotherapy, you will want to make compression socks a part of your daily routine to prevent a pulmonary embolism until you can become more active. These compression socks will encourage positive blood flow. You’ll want to get as much physical activity as possible when you can. If you’ve noticed any swelling in your legs, keep your feet elevated twice a day for a half hour, as that also encourages positive blood flow in your legs.

To reduce your risk of pulmonary embolism, you’ll also need to maintain the following like most conditions:

  • Drinking plenty of water and healthy fluids daily
  • Avoiding poor conditions such as smoking or using other tobacco products.
  • Keeping your weight manageable and not overweight

Treatments For a Pulmonary Embolism


The most common treatment that patients receive when diagnosed with a pulmonary embolism is a round of blood thinners. Depending on the severity and location of the blood clot, you may have to stay overnight at the hospital where you’re being monitored. Some severe cases may need thrombolytic therapy, where an IV line is used to prevent blood clots and reduce the long-term damage to the lungs and heart if it causes a heart attack. Some patients will require cloot removal using catheters and other clot removal devices. Long-term treatment options may keep you on blood thinners for an extended period.
