If urgent treatment is needed, supplemental oxygen is given to the individual. Treatments can range from surgery to correct dangerous intracranial pressure, to stays in rehabilitation facilities for bradypnea caused by addiction problems.
The alveolar oxygen is transferred to hemoglobin, a carrier protein inside red blood cells, with an efficiency that decreases with the partial pressure of oxygen in the air. Altitude. The external partial pressure of oxygen decreases with altitude, for example in areas of high altitude or when flying.
Hypopnea is typically defined by a decreased amount of air movement into the lungs and can cause hypoxemia (low levels of oxygen in the blood.) It commonly is due to partial obstruction of the upper airway, but can also have neurological origins in central sleep apnea.
Following are terms that specify a type of lung size and/or activity. More specific definitions may be found in individual articles. Eupnea – normal breathing; Apnea – absence of breathing
Venous oxygen saturation (SvO 2) is the percentage of oxygenated hemoglobin returning to the right side of the heart. It can be measured to see if oxygen delivery meets the tissues' demands. SvO 2 typically varies between 60% and 80%. [9] A lower value indicates that the body is in lack of oxygen, and ischemic diseases occur.
As a side effect of medicines or recreational drugs, hypoventilation may become potentially life-threatening.Many different central nervous system (CNS) depressant drugs such as ethanol, benzodiazepines, barbiturates, GHB, sedatives, and opioids produce respiratory depression when taken in large or excessive doses, or mixed with other depressants.

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 ...
