A decreased respiratory drive can also be the result of metabolic alkalosis, a state of decreased carbon dioxide in the blood; Central sleep apnea. During sleep, the breathing centers of the brain can pause their activity, leading to prolonged periods of apnea with potentially serious consequences. Hyperventilation followed by prolonged breath ...
Decreasing metabolic rate by reducing body temperature lowers oxygen demand and consumption, and can minimise the effects of tissue hypoxia, especially in the brain, and therapeutic hypothermia based on this principle may be useful. [8] Where the problem is due to respiratory failure. it is desirable to treat the underlying cause.
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 ...

The term is sometimes inaccurately used to refer to labored, gasping breathing patterns accompanying organ failure, systemic inflammatory response syndrome, septic shock, and metabolic acidosis. End-of-life inability to tolerate secretions, known as the death rattle , is a different phenomenon.
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
Severe respiratory disorders, where spontaneous breathing is not enough to maintain life, may need the use of mechanical ventilation to ensure an adequate supply of air. Cancers Lung cancer can either arise directly from lung tissue or as a result of metastasis from another part of the body.
The tunicate epicardium separates digestive organs from the pharynx and heart, but the anus returns to the upper compartment to discharge wastes through an outgoing siphon. Thus the diaphragm emerges in the context of a body plan that separated an upper feeding compartment from a lower digestive tract, but the point at which it originates is a ...
