Pneumonia And Blood Clots In Lungs

What Is The Clotting Problem That You And Other Doctors Are Seeing In Severe Covid

Pulmonary embolism: The route to recovery

Many COVID-19 patients in the ICU are developing blood clots, including clots in small vessels, deep vein thromboses in the legs, clots in the lungs, and stroke-causing clots in cerebral arteries. This has been happening even though these patients, in accordance with standard intensive care practice, are put on blood thinner drugs such as heparin to prevent clots as soon as they come to the ICU. This COVID-19-related clotting often does not respond well to standard prevention methods and, in some cases, to standard treatments, even with high doses of blood thinners.

Did This Years Flu Shot Cause Persistent Arm Pain

How can you keep from getting the flu? The answer from the CDC has long been get your flu shot. When people ask about side effects they are told reactions are rare and mild, disappearing within a day or two.

Starting last year, however, we began receiving complaints from readers who experienced long-lasting severe arm pain after getting their annual influenza vaccine. One nurse sent this message:

What Increases Your Risk Of Having A Pulmonary Embolism

If youve been inactive for a long time, your chance of getting a pulmonary embolism increases. This is because when youre inactive, blood tends to collect in the lower parts of your body, particularly in your lower legs.

This isnt usually a problem because when you start to move, your blood flow increases, and blood begins to move more evenly round your body. But if youre immobile for a long time, the flow of blood around your body can slow and clot, causing a DVT that can break off and cause a pulmonary embolism.

This can happen:

  • after an operation or a serious limb injury
  • after long periods of bed rest
  • during a long-haul flight or a long train or car journey lasting more than 4 hours

Around half of all people with a pulmonary embolism get it during a long stay in hospital.

Is It Possible To Prevent Pulmonary Embolism

  • Take blood thinners as usual. Its also crucial to visit your doctor on a frequent basis to ensure that the dosage of your medications is effective in preventing blood clots without causing bleeding.
  • Changes in your lifestyle that are good for your heart, such as heart-healthy eating, exercise, and, if you smoke, quit.
  • Compression stockings are used to prevent deep vein thrombosis . When sitting for long periods of time, move your legs
  • After surgery, you should be able to move around as quickly as possible rather than being restricted to a bed.

This is not a normal health issue, one should take it very seriously as this is a pretty serious issue and one should immediately consult the best lung specialist or a pulmonologist who can help them understand the severity of PE and the treatment according to it. Dr. Satya Ranjan Sahu is one of the best chest specialists in Delhi NCR whom you can consult if you are dealing with any type of lung problem. He is one of the best pulmonologists in Delhi who has years of experience in treating the problem of Pulmonary Embolism. So, refer to Dr. Satya Ranjan Sahu, the best pulmonologist in Delhi and Gurugram because if not treated immediately PE can quickly cause serious life-threatening consequences and death.

What Are The Complications Of A Pulmonary Embolism

Study finds COVID

A pulmonary embolism can cause a lack of blood flow that leads to lung tissue damage. It can cause low blood oxygen levels that can damage other organs in the body, too.

A PE, particularly a large PE or many clots, can quickly cause serious life-threatening problems and, even death.

Treatment of a PE often involves anti-coagulation medicines or blood thinners. These medicines can put you at a risk for excessive bleeding if they thin your blood too much. Excessive bleeding is bleeding that won’t stop after you apply pressure for 10 minutes. Other symptoms of bleeding to watch for include:

Signs of bleeding in the digestive system:

  • Bright red vomit or vomit that looks like coffee grounds

  • Bright red blood in your stool or black, tarry stools

  • Abdominal pain

Signs of bleeding in the brain:

  • Severe headache

  • Sudden loss of movement or feeling in your legs or arms

  • Memory loss or confusion

Treatment to prevent DVTs includes:

What Could Have Caused My Dog To Have A Pulmonary Thromboembolism

There are many important considerations and potential causes of PTE in dogs. Canine heartworm disease is one potential cause, emphasizing the need to provide appropriate monthly protection against heartworm disease. Other important potential causes of canine thromboembolism include cancer, excessive levels of steroids produced by the adrenal glands in Cushings disease, steroid medications, and kidney disease in which protein is lost into the urine.

Other potential causes of pulmonary thromboembolism include:

  • immune-mediated hemolytic anemia , in which the dogs immune system destroys the dogs own red blood cells
  • pancreatitis
  • clotting of the blood within the blood vessels, called disseminated intravascular coagulopathy

When Would I Need To Be Hospitalized For Pneumonia

If your case of pneumonia is more severe, you may need tostay in the hospital for treatment. Hospital treatments may include:

  • Oxygen
  • Fluids, antibiotics and other medicines given through an IV
  • Breathing treatments and exercises to help loosen mucus

People most likely to be hospitalized are those who are most frail and/or at increased risk, including:

  • Babies and young children
  • People with weakened immune systems
  • People with health conditions that affect the heart and lungs

It may take six to eight weeks to return to a normal level of functioning and well-being if youve been hospitalized with pneumonia.

What Do Blood Clots In The Lungs Feel Like

Blood clots in the lungs happen suddenly. If you pay attention to how abruptly your symptoms started, you will be able to help your doctor think about a blood clot in the lungs as the possible cause of your symptoms.

There are many possible symptoms of blood clots in the lungs. You may only have one or two symptoms, but it is important to pay attention to how you feel. Even with seemingly mild symptoms, you feel very distressed when you have blood clots in your lungs. You feel like something just took out all your energy.

What Is The Outlook For My Dog

Does Coronavirus Cause Permanent Lung Damage? Does COVID Cause Blood Clots?

The prognosis for dogs with pulmonary thromboembolism is generally guarded to poor, and it depends upon resolution of the underlying cause. Dogs for whom the cause of their pulmonary thromboembolism is trauma or generalized bacterial infection tend to have a better prognosis.

Future episodes of pulmonary thromboembolism are likely unless an underlying cause is identified and corrected. These blood clots are often fatal, and sudden death is not unusual. Treatment with anticoagulant medications can lead to bleeding.

Immune Dysfunction In Severe Covid

Could the bodyâs response to the virus cause more harm than good? Virus persisting in the body or significant damage to the lungs and blood vessels as described above may lead to inflammatory over-reaction in the most severe cases. Labels linked to overactive inflammatory responses to infection, such as hyper-inflammatory syndrome, cytokine storm and viral sepsis, have been repurposed for COVID-19, but a lack of current scientific understanding means that they do not have precise definitions.

As part of a healthy immune response, infection-fighting white blood cells recognise the virus. They release chemicals called cytokines that attract other immune cells to the site of an infection. These are activated so that they can kill cells infected with the virus. But if too many cytokines are released in a short period, cells not infected by virus may also be killed â causing collateral damage. In patients with severe COVID-19, cytokine levels are far higher than in patients with mild disease.

Treatments targeting the inflammatory response, rather than the virus itself, exist for severe COVID-19. Steroid therapy dampens the immune response in general, but newer treatments are emerging that can block specific cytokines involved in these harmful responses. The concern with these new treatments is that they may impede protective immune responses as well, which is why drug trials are underway to measure their benefits and risks.

How Is Pulmonary Thromboembolism In Dogs Treated

Many dogs with thromboembolism are first treated as inpatients until the oxygen levels in their blood return to normal. Oxygen therapy may be a part of their treatment, but response to oxygen therapy may be variable. Once the dog returns home, it is important to restrict activity to prevent worsening of low levels of oxygen in the blood or fainting.

“Once the dog returns home, it is important to restrict activity to prevent worsening of low levels of oxygen in the blood or fainting.”

There are some medications available for treating this disorder. Heparin is a medication to prevent blood from clotting that may help to prevent future clots from forming, but will not cause existing clots to break up. Warfarin is another anticoagulant that may be considered for long-term treatment. With it, dosage adjustments are necessary to keep blood clotting at a specific level, and carefully balancing the risk of further clots with the risk of bleeding complications is needed to prevent development of further clots.

Anti-platelet medications such as clopidogrel or Aspirin are also sometimes used as a preventive medication in dogs with disorders that might put them at increased risk for developing PTE.

Medications to dissolve existing clots have been tried but their effective use without complications is not clear.

Who Is At Risk For Getting Fluids In The Lungs From Pneumonia

Medical research has identified different groups of people that are at a higher risk of getting fluid buildup in the lungs from pneumonia.

Here are those gruops:

  • People who had a delay in starting antibiotics for their pneumonia: Those who were diagnosed late and received antibiotics more than six days from the start of pneumonia had higher risks of getting fluids in the lungs from pneumonia.
  • People with a history of alcoholism: Alcoholics are more likely to develop fluids in the lungs from pneumonia than non-alcoholics
  • Malnourished people: People who are malnourished are also more likely to get fluids in the lungs from pneumonia
  • Low sodium: If your sodium is lower than 130 mg/dl, you are at a high risk of getting fluids in the lungs
  • History of drug abuse: If you have a history of drug abuse, especially injections, you are at a higher risk of getting fluids in the lungs from pneumonia.
  • Very high inflammatory markers: There are certain blood tests that indicate the level of inflammation in the body. When you have very high levels of these inflammatory markers, you are more likely to get fluids in the lungs.

    What Is Life Like After Pulmonary Embolism

    Most patients can maintain a good quality of life after treatment. Depending on the underlying cause of the pulmonary embolism, patients remain on anticoagulation medication for several weeks to months after treatment to prevent clots from redeveloping, with periodic checkups for incidence of bleeding.

    In some cases, this may result in some dietary adjustments .

    Can Coronavirus Patients Lessen The Chance Of Lung Damage

    There are things patients can do to increase their chances for less severe lung damage, Galiatsatos says.

    If you have a health issue that puts you at higher risk, make sure youre doing everything you can to minimize the chance of contracting the virus. Also, make sure that your chronic health conditions are managed as well as they can be. For example, people living with diabetes, COPD or heart disease should be especially careful to manage those conditions with monitoring and taking their medications as directed.

    Galiatsatos adds that proper nutrition and hydration can also help patients avoid complications of COVID-19. Staying well fed is important for overall health. Proper hydration maintains proper blood volume and healthy mucous membranes in the respiratory system, which can help them better resist infection and tissue damage.

    What is Pulmonary embolism? Causes, Signs and Symptoms of Blood clot in Lungs

    What is a pulmonary embolism?

    A pulmonary embolism is a blood clot that occurs in the lungs.

    It can damage part of the lung due to:

    • restricted blood flow
    • effects on other organs

    Large or multiple blood clots can be life threatening. However, immediate emergency treatment for a PE greatly increases your chances of avoiding permanent lung damage.

    Explore the interactive 3-D diagram below to learn more about pulmonary embolism symptoms.

    Symptoms of a PE depend on the size of the clot and where it gets stuck in the lung.

    The most common symptom of a PE is shortness of breath. This may be gradual or sudden.

    Bacterial Pneumonia Causes Lesions In The Heart

    By analyzing the tissue of animals and humans sick with pneumonia, researchers were able to conclude that the bacteria that is responsible for pneumonia spreads across the endothelial cells in the cardiac arteries and infects the heart. The bacteria can cause tiny lesions within the myocardium of the heart. The myocardium is the muscular middle layer of the wall of the heart. The micro lesions leave the heart scarred and later lead to necrosis of myocardiocytes. The heart cells are killed off by a poisonous substance, pneumolysin, which is produced by the bacteria. It is still not clear whether these lesions increase the chance of death directly, or if they hurt cardiac function, thus creating heart problems.

    What Does It Mean To Have Fluid In The Lungs From Pneumonia

    Pneumonia is an infection of the lungs. It can have many complications. One of the complications of pneumonia is presence of fluids in the chest. Medically, it is called para-pneumonic effusion, which is a type of pleural effusion.

    Dont worry, I will explain in details what that means. I will also tell you where and how the fluid buildup occurs.

    Your lungs are covered by a double layered lining. There is a small amount of fluid in-between the two linings. This layer of fluid acts as a lubricant and helps make lung movement smooth.

    With pneumonia, sometimes the infection and inflammation may spread out from the lungs to reach the inner lining. The infection may then involve the layer of lubricating fluid. To fight the infection, your body tries to send more white blood cells in the area where the lubricating fluid lives. To do that, they widen the gap in the small arteries that supply blood to the area. More white blood cells rush to the area and take extra fluids with them. Eventually, fluid buildup begins in the lungs.

    As you can see, fluids in the lungs from pneumonia builds up in-between the two layers. This area is medically called pleural space, and thats why this type of fluid buildup is called pleural effusion. When pleural effusion is caused by pneumonia, it is called para-pneumonic effusion.

    What To Do Next

    After you get proper treatment for a lung embolism at the hospital, youll be advised to treat the underlying cause. This is typically deep vein thrombosis.

    Youll most likely start taking anticoagulant medications, such as heparin and warfarin, to prevent blood clots from returning. You may also have to use compression stockings or another device to prevent clots from forming in your legs.

    Frequently exercising your legs is likewise a key part of therapy after a lung embolism. Your doctor will provide you total instructions on how to look after yourself to prevent future blood clots.

    What Causes Blood Clots In The Lungs

    Student, 19, who suffered life

    Pulmonary embolism can be caused by many factors:

    • Surgery, especially surgery on the abdomen, hip, and knees
    • Bone fracture, especially long bone fractures such as of the thigh bone
    • A long period of confinement to the bed or a wheelchair
    • Prolonged hospitalization
  • Thrombolytic therapy to dissolve the existing clots.
  • Surgery may be needed to remove a very large, life-threatening clot.
  • Compression stockings may be useful to prevent the recurrence of pulmonary embolism, as most of the clots in the lungs originate in the legs.
  • A vena cava filter may be surgically placed in a large vein of the abdomen called the vena cava. It can filter out or catch blood clots from the legs before they reach the lungs.
  • Management of risk factors .
  • Suitable attention must be given to reduce the risk of bleeding while on anticoagulants. The doctor may advise avoiding certain foods, alcohol, or some over-the-counter medications .
  • People on blood thinners should not overexert themselves during exercises.
