If the patient is diagnosed with pericardial effusion, it is generally recommended that the patient remain in a semi-recumbent position, or with legs dangling, to reduce cardiac load and improve symptoms. This is because the main complication of pericardial effusion is the occurrence of myocardial ischemia, or myocardial necrosis. Additionally, the primary treatment for pericardial effusion is still based on pericardiocentesis to improve cardiac function. During this period, it is also essential to actively monitor changes in the patient's blood pressure. If the patient's blood pressure is too high, antihypertensive medications should be used. Generally, a semi-recumbent position is still recommended for patients with pericardial effusion.
