Platypnea
Platypnea
Platypnea (/plætɪpˈniːə/; from the Greek platys meaning "flat" and pnoia meaning "breath") is a medical condition characterized by shortness of breath (dyspnea) that is relieved when lying down, and worsens when standing up or sitting.
Etymology
The term "platypnea" originates from the Greek words platys (flat) and pnoia (breath). It was first used in medical literature in the 20th century to describe a specific pattern of dyspnea that is opposite to the more common condition known as orthopnea.
Symptoms
The primary symptom of platypnea is shortness of breath that worsens upon standing or sitting up. This can be accompanied by orthodeoxia, a related condition where the level of oxygen in the blood decreases when a person stands up.
Causes
Platypnea can be caused by a variety of conditions, including liver disease, heart disease, and lung disease. It can also be a symptom of hepatopulmonary syndrome, a condition that affects the lungs in people with advanced liver disease.
Diagnosis
Diagnosis of platypnea involves a physical examination and a review of the patient's medical history. Additional tests may be required to determine the underlying cause of the condition, such as a chest X-ray, echocardiogram, or liver function tests.
Treatment
Treatment for platypnea is primarily focused on managing the underlying condition causing the symptom. This may involve medication, surgery, or other interventions depending on the specific cause.
