Hypoxic hypoxia – Limited oxygen in the environment causes reduced brain function. Divers, aviators, [24] mountain climbers, and fire fighters are all at risk for this kind of cerebral hypoxia. The term also includes oxygen deprivation due to obstructions in the lungs. Choking, strangulation, the crushing of the windpipe all cause this sort ...
Hypoxia can be due to external causes, when the breathing gas is hypoxic, or internal causes, such as reduced effectiveness of gas transfer in the lungs, reduced capacity of the blood to carry oxygen, compromised general or local perfusion, or inability of the affected tissues to extract oxygen from, or metabolically process, an adequate supply ...
Tissue hypoxia refers to low levels of oxygen in the tissues of the body and the term hypoxia is a general term for low levels of oxygen. [2] Hypoxemia is usually caused by pulmonary disease whereas tissue oxygenation requires additionally adequate circulation of blood and perfusion of tissue to meet metabolic demands.
Symptoms include chest pain or pain that comes and goes, radiating to the jaw and either arm, fatigue, heart palpitations (myocarditis can cause heart arrhythmias), lightheadedness, shortness of ...
Generalized hypoxia is a medical condition in which the tissues of the body are deprived of the necessary levels of oxygen due to an insufficient supply of oxygen, which may be due to the composition or pressure of the breathing gas, decreased lung ventilation, or respiratory disease, any of which may cause a lower than normal oxygen content in the arterial blood, and consequently a reduced ...
Fibromyalgia, which causes pain and fatigue throughout the body Lupus, which can cause inflammation in many parts of the body, such as your joints, blood cells and organs Multiple sclerosis, which ...
Type I respiratory failure is caused by conditions that affect oxygenation and therefore lead to lower-than-normal oxygen in the blood. These include: Low ambient oxygen (e.g. at high altitude). [1] Ventilation-perfusion mismatch (parts of the lung receive oxygen but not enough blood to absorb it, e.g. pulmonary embolism, Acute respiratory ...
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.
