When a blood clot forms within a vein and remains in place, it is referred to as a thrombus. However, if this clot dislodges from the vein wall and travels to another part of the body, it is known as an embolus. In the case of a pulmonary embolus, the embolus has originated from a different location in the body and is now obstructing an artery within the lung. This condition, known as pulmonary embolism, is a grave medical concern that can pose a life-threatening risk, particularly when the clot is sizable or when multiple blockages occur simultaneously.
Identifying Common Symptoms of a Pulmonary Embolism
When it comes to a pulmonary embolism, the symptoms can differ based on factors such as the size of the clot, the extent of lung tissue involvement, and the presence of any pre-existing heart or lung conditions. Recognizing the signs is crucial, and they often include a sudden onset of shortness of breath that worsens with physical activity, significant chest pain, and a persistent cough that may produce secretions tinged with blood. However, it is important to note that approximately half of all individuals with a pulmonary embolism may not experience any symptoms at all.
Other Possible Symptoms of Pulmonary Embolism
Aside from the common symptoms mentioned earlier, there are additional signs that can manifest depending on the seriousness of the pulmonary embolism. It is important to be aware of these symptoms as they can provide further insight into the condition. Some individuals may notice that their skin becomes clammy or discolored. Others may experience a fever, excessive sweating, feelings of lightheadedness, or an irregular or rapid heart rate. It is also possible to develop pain or swelling in one or both calves, which could indicate the presence of deep vein thrombosis – a condition that may have caused the initial blood clot.
