• Orthopnea is often a symptom of left ventricular heart failure and / or pulmonary edema.
• The consequences of this are dyspnea ( shortness of breath ), orthopnea and paroxysmal nocturnal dyspnea.
• Orthopnea is the opposite of platypnea, shortness of breath that worsens when sitting or standing up.
• "' Orthopnea "'fluid redistribution into the central circulation, causing an increase in pulmonary capillary pressure.
• Thus, left-sided heart failure often presents with respiratory symptoms : shortness of breath, orthopnea and paroxysmal nocturnal dyspnea.
• It is often measured in the number of pillows required to lie comfortably, and in orthopnea, the patient may resort to sleeping while sitting up.
