When a person is recumbent, or is lying down, blood is redistributed from the lower extremities and abdominal cavity (splanchnic circulation) to the lungs. [5] Failure to accommodate this redistribution results in decreased vital capacity and pulmonary compliance , further causing the shortness of breath experienced in PND.
A related condition, orthodeoxia, describes the clinical finding of low oxygen saturation in the upright position, which improves when lying down. [3] Platypnea and orthodeoxia (low oxygen levels when in upright posture) can co-exist, and this combination is named platypnea-orthodeoxia syndrome. [4] [5] The syndrome is considered extremely rare ...
"That can cause a sharp chest pain that can also spread to your left arm or shoulder," Lala says. "It can be worse when you're lying down or when you're taking deep breaths." Coronary artery ...
Other signs include end-inspiratory crackles (crackling sounds heard at the end of a deep breath) on auscultation and the presence of a third heart sound. [3] Shortness of breath can manifest as orthopnea (inability to breathe sufficiently when lying down flat) and/or paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at ...
Also known as 'effort angina', this refers to the classic type of angina related to myocardial ischemia.A typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin.

Whether you’re starting a new running workout or have been pounding the pavement for years, you’re probably inclined to think sharp chest pain means the worst—a heart attack. Here’s what ...
Psychogenic causes of chest pain can include panic attacks; however, this is a diagnosis of exclusion. [12] In children, the most common causes for chest pain are musculoskeletal (76–89%), exercise-induced asthma (4–12%), gastrointestinal illness (8%), and psychogenic causes (4%). [13] Chest pain in children can also have congenital causes.
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
