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.
Platypnea or platypnoea is shortness of breath (dyspnea) that is relieved when lying down, and worsens when sitting or standing upright. It is the opposite of orthopnea. [1] The condition was first described in 1949 and named in 1969.
Orthopnea or orthopnoea [1] is shortness of breath (dyspnea) that occurs when lying flat, [2] causing the person to have to sleep propped up in bed or sitting in a chair. It is commonly seen as a late manifestation of heart failure, resulting from fluid redistribution into the central circulation, causing an increase in pulmonary capillary pressure and causing difficulty in breathing.
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 ...
A great technique for easing stress is 4-7-8 breathing. It's easy to learn and could help ease inflammation and immunity. Here's how to do it.
Catathrenia begins with a deep inspiration. The person with catathrenia holds his or her breath against a closed glottis, similar to the Valsalva maneuver. Expiration can be slow and accompanied by sound caused by vibration of the vocal cords or a simple rapid exhalation. Despite a slower breathing rate, no oxygen desaturation usually occurs.
According to a new study published in Neurology, poor sleep is linked to a higher risk of dementia. Neurologists explain the link—and how to prevent dementia.
Here's how to distinguish "sundowning"—agitation or confusion later in the day in dementia patients—from typical aging, from doctors who treat older adults.
