Pulmonary embolism (PE) is a life-threatening condition that requires immediate medical attention. It occurs when a blood clot forms in a blood vessel, often in the leg, and travels to the lung, causing a blockage in the pulmonary artery. The best way to prevent PE is to minimise the risk factors associated with blood clots, such as deep vein thrombosis (DVT). Leading a healthy and active lifestyle, quitting smoking, and maintaining mobility can significantly reduce the chances of developing PE. Hospitalised patients are typically treated with injections of blood thinners or anticoagulants to prevent the clot from growing and to avoid the formation of new clots.

What You'll Learn
Prevent deep vein thrombosis (DVT)
Deep vein thrombosis (DVT) is a blood clot that develops in a deep vein, usually in the leg. It is a serious condition that requires immediate medical attention as it can lead to pulmonary embolism (PE) if left untreated. PE occurs when the clot breaks loose, travels through the bloodstream to the lungs, and forms a blockage in the lung artery, restricting blood flow and oxygen supply to the lungs.
To prevent DVT and the subsequent risk of PE, it is important to maintain an active lifestyle and healthy blood flow. If you have a desk job or are required to sit for long periods, it is recommended to frequently stand, stretch, and take walking breaks. While seated, flex and move your legs and feet to promote circulation. When travelling on long car or plane rides, it is advised to move as much as possible. Avoid crossing your legs for extended periods. If flying, perform simple leg exercises such as lifting your knees and rotating your ankles, and stand up and walk when safe to do so. During car journeys, take regular breaks to stretch and move around.
Staying properly hydrated is another way to reduce the risk of blood clots. Drinking plenty of water is always important, especially when you've been inactive for several hours. Dehydration can increase the likelihood of clotting.
Quitting smoking is also recommended to reduce the risk of DVT and PE. Toxic chemicals in cigarettes harm blood cells and blood vessels, making it easier for clots to form and increasing your susceptibility to DVT and PE.
Additionally, being aware of and managing other risk factors can help prevent DVT. These factors include family history, age (over 60), certain cancers, use of oral contraceptives or hormone therapy, and being overweight. If you have concerns about these risk factors, consult your doctor to discuss alternatives and personalised advice.

Stay active and hydrated
Staying active and hydrated is crucial for preventing pulmonary embolism, especially if you're at risk due to prolonged immobility. Here are some ways to do that while in hospital:
Stay Active
If you're in hospital and confined to a bed, it's important to move your legs and feet as much as possible. Simple exercises like flexing and rotating your ankles can help promote healthy blood flow. You can also try lifting your knees and moving your legs and feet in a marching motion. If you're able to get out of bed, take walks around the ward or hospital, but always follow your doctor's advice and move within your capacity.
Take Breaks from Sitting
If you're sitting in a chair, avoid crossing your legs for long periods. Get up and walk around as often as you're able. If you're in a wheelchair, ask a nurse or caregiver about safe ways to stretch and move your legs to improve blood flow.
Stay Hydrated
Drinking plenty of water is crucial, especially when you've been inactive for a while. Dehydration increases the risk of blood clots, so make sure you have easy access to water and drink regularly throughout the day.
Preventative Measures
If you're at risk of developing blood clots, your doctor may recommend compression stockings to improve blood flow and prevent clots from forming in your legs. It's important to follow their advice and wear them as directed. Additionally, if you smoke, quitting can significantly reduce your risk of pulmonary embolism.
Remember, if you're in hospital, your healthcare team will provide specific advice and support to prevent pulmonary embolism based on your individual needs and risk factors.

Avoid crossing legs for long periods
Crossing your legs for extended periods can increase your risk of developing a pulmonary embolism (PE). This is because the position can restrict blood flow and oxygen levels in your legs, which can lead to the formation of blood clots. These blood clots can then travel to the lungs and cause a pulmonary embolism.
A pulmonary embolism is a blockage in the arteries of the lungs, usually caused by blood clots that develop in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can break loose and travel through the bloodstream to the lungs, where they block blood flow and starve lung tissue of oxygen. As a result, the lungs cannot provide enough oxygen to the rest of the body, leading to serious complications or even death.
To prevent pulmonary embolism, it is crucial to minimise the risk of developing blood clots in the legs. This includes avoiding crossing your legs for long periods and maintaining active and mobile habits. Simple actions such as standing, stretching, and taking walking breaks throughout the day can promote healthy blood flow and reduce the likelihood of clot formation.
If you must remain seated for extended periods, there are still ways to improve blood flow in your legs. You can flex and move your legs and feet while seated. Additionally, staying hydrated by drinking plenty of water is essential, especially after long periods of immobility.
In summary, avoiding crossing your legs for long periods is an important step in preventing pulmonary embolism. This is because the position can restrict blood flow and oxygen levels in the legs, increasing the risk of blood clot formation. By maintaining active habits and staying hydrated, you can help reduce the chances of developing a pulmonary embolism.

Discuss medication risks
Medication is a crucial aspect of preventing and treating pulmonary embolism (PE), but it also comes with certain risks that patients and healthcare providers should carefully consider.
One of the primary medications used to prevent and treat PE is anticoagulants, also known as blood thinners. While these medications are highly effective in preventing blood clots, they also increase the risk of bleeding. Patients on anticoagulants may be advised to avoid certain foods rich in vitamin K, alcohol, and some over-the-counter medicines like aspirin and sleeping pills. It is crucial for patients to understand how and when to take their medication and to follow their doctor's guidelines closely.
Thrombolytic medications, also known as "clot busters," are another option for treating PE. These medications, including tissue plasminogen activator (TPA), dissolve blood clots. However, they are typically used in emergency situations or intensive care settings where patients can be closely monitored due to the potential risks associated with their use. Thrombolytics may be considered for patients with special situations, such as low blood pressure or unstable conditions due to PE.
In addition to medication, preventive measures are essential to reduce the risk of PE. Leading an active lifestyle, staying mobile, and avoiding prolonged immobility can decrease the chances of developing blood clots. For those who work at desks or travel frequently, it is important to take breaks, stretch, and move their legs and feet to promote healthy blood flow. Staying hydrated is also crucial, as dehydration can increase the risk of blood clots.
For patients who smoke, quitting is strongly recommended as toxic chemicals in cigarettes harm blood cells and blood vessels, making individuals more susceptible to deep vein thrombosis and PE. Hormone replacement therapy and oral contraceptives are also associated with an increased risk of developing blood clots, especially when combined with smoking or being overweight. It is important for patients to discuss these risks with their doctors and explore alternative treatments if necessary.
