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.
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 ...
Hypoxemia normally stimulates ventilation and produces dyspnea, but these and the other signs and symptoms of hypoxia are sufficiently variable in COPD to limit their value in patient assessment. Chronic alveolar hypoxia is the main factor leading to development of cor pulmonale — right ventricular hypertrophy with or without overt right ...
Silent hypoxia (also known as happy hypoxia) [1] [2] is generalised hypoxia that does not coincide with shortness of breath. [ 3 ] [ 4 ] [ 5 ] This presentation is known to be a complication of COVID-19 , [ 6 ] [ 7 ] and is also known in walking pneumonia , [ 8 ] altitude sickness , [ 9 ] [ 10 ] [ 11 ] and rebreather diving .
Generally, old age tends to reduce the efficiency of the pulmonary system, and can cause the onset of hypoxia symptoms sooner. [3] Smoking drastically reduces oxygen intake efficiency, and can have the effect of reducing tolerance by 1,000–2,000 metres (3,300–6,600 ft). [4] Hypoxia can be produced in a hypobaric chamber. This can be useful ...
