'''Orthopnea''' is a medical condition characterized by [[dyspnea]], or difficulty breathing, that occurs when a person is lying flat. This condition is often relieved by sitting or standing up.

Difficulty breathing when lying flat
Orthopnea is a medical condition characterized by dyspnea, or difficulty breathing, that occurs when a person is lying flat. This condition is often relieved by sitting or standing up. Orthopnea is commonly associated with heart failure, but it can also be seen in other conditions such as obesity, asthma, and chronic obstructive pulmonary disease (COPD).
Pathophysiology[edit]
Orthopnea occurs due to the redistribution of body fluids when a person lies down. In a supine position, blood from the lower extremities is redistributed to the central circulation, increasing the volume of blood returning to the heart. In individuals with compromised cardiac function, such as those with heart failure, the heart may not be able to handle this increased preload, leading to pulmonary congestion and difficulty breathing.
Causes[edit]
Orthopnea is most commonly associated with:
- Heart failure: In heart failure, the heart's ability to pump blood is impaired, leading to fluid accumulation in the lungs when lying flat.
- Obesity: Excess body weight can restrict lung expansion and diaphragm movement, exacerbating breathing difficulties when supine.
- COPD: Patients with COPD may experience orthopnea due to increased airway resistance and reduced lung volumes.
- Asthma: Asthma can cause orthopnea due to airway inflammation and bronchoconstriction.
Symptoms[edit]
The primary symptom of orthopnea is difficulty breathing when lying flat. Patients may report needing to sleep propped up on pillows or in a chair to alleviate symptoms. Other associated symptoms can include:
Diagnosis[edit]
Diagnosis of orthopnea is primarily clinical, based on the patient's history and symptoms. A thorough physical examination and medical history are essential. Additional diagnostic tests may include:
- Chest X-ray: To assess for pulmonary congestion or other abnormalities.
- Echocardiogram: To evaluate cardiac function and structure.
- Pulmonary function tests: To assess lung function and identify obstructive or restrictive patterns.
Management[edit]
Management of orthopnea involves treating the underlying cause. General measures include:
- Positioning: Encouraging patients to sleep with the head elevated or in a sitting position.
- Medications: Diuretics, beta-blockers, and ACE inhibitors for heart failure; bronchodilators and corticosteroids for asthma and COPD.
- Lifestyle modifications: Weight loss in obese patients, smoking cessation, and avoiding allergens or irritants.
Prognosis[edit]
The prognosis of orthopnea depends on the underlying cause and the effectiveness of treatment. In heart failure, effective management can significantly improve symptoms and quality of life. In chronic respiratory conditions, controlling inflammation and airway obstruction is key to reducing symptoms.
