ANATOMY

Detailed explanation-1: -Orthopnea is shortness of breath or difficulty breathing when you’re lying down. It comes from the Greek words “ortho, ” which means straight or vertical, and “pnea, ” which means “to breathe.” If you have this symptom, your breathing will be labored when you lie down. It should improve once you sit up or stand.

Detailed explanation-2: -When fluid builds up, it disrupts the exchange, making it harder for the lungs to distribute oxygen back into the bloodstream. It’s easier for the lungs to clear out excess fluid when they’re in an upright position, which is why orthopnea symptoms are relieved once the person stops lying down.

Detailed explanation-3: -Orthopnea means shortness of breath when lying down. It can result from various health conditions, including heart failure and obesity. Treatment will depend on the underlying cause. However, sleeping with the heads propped up on pillows may help manage symptoms.

Detailed explanation-4: -Orthopnea is the sensation of breathlessness in the recumbent position, relieved by sitting or standing. Paroxysmal nocturnal dyspnea (PND) is a sensation of shortness of breath that awakens the patient, often after 1 or 2 hours of sleep, and is usually relieved in the upright position.

Detailed explanation-5: -The most common cause of orthopnea is due to heart disease, such as congestive heart failure, coronary artery disease, or valvular dysfunction. In heart failure or coronary artery disease, the left ventricle may be unable to adequately pump blood into systemic circulation.
