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.
In COVID-19, the arterial and general tissue oxygen levels can drop without any initial warning.The chest x-ray may show diffuse pneumonia.Cases of silent hypoxia with COVID-19 have been reported for patients who did not experience shortness of breath or coughing until their oxygen levels had depressed to such a degree that they were at risk of acute respiratory distress (ARDS) and organ failure.
Oxygen therapy may be used if oxygen levels are low. [11] Each year, pneumonia affects about 450 million people globally (7% of the population) and results in about 4 million deaths. [12] [13] With the introduction of antibiotics and vaccines in the 20th century, survival has greatly improved. [12]

Hypoxia can result from a failure at any stage in the delivery of oxygen to cells. This can include low partial pressures of oxygen in the breathing gas, problems with diffusion of oxygen in the lungs through the interface between air and blood, insufficient available hemoglobin, problems with blood flow to the end user tissue, problems with ...
Hypopnea is overly shallow breathing or an abnormally low respiratory rate. 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.
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...
Untreated or prolonged upper airway obstruction can cause severe, life-threatening complications. Hypoxia: Low blood oxygen can cause confusion and unconsciousness. It can also lead to cardiac arrest if not treated. [1] [page needed] Aspiration pneumonia: Particles entering the lungs can cause infections. [8]
