Hypoxemia (also spelled hypoxaemia) is an abnormally low level of oxygen in the blood. [1] [2] More specifically, it is oxygen deficiency in arterial blood. [3] Hypoxemia is usually caused by pulmonary disease. Sometimes the concentration of oxygen in the air is decreased leading to hypoxemia.
Potentially life-threatening hypoxemia is common in critically ill patients. [113] Localized hypoxia may be a complication of diabetes, decompression sickness, and of trauma that affects blood supply to the extremities. Hypoxia due to underdeveloped lung function is a common complication of premature birth.
The tissue in the lungs becomes thick and stiff, which affects the tissue that surrounds the air sacs in the lungs. [7] Symptoms typically include gradual onset of shortness of breath and a dry cough. [1] Other changes may include feeling tired, and clubbing abnormally large and dome shaped finger and toenails.

Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
By redirecting blood flow from poorly-ventilated lung regions to well-ventilated lung regions, HPV is thought to be the primary mechanism underlying ventilation/perfusion matching. [ 1 ] [ 2 ] The process might initially seem counterintuitive, as low oxygen levels might theoretically stimulate increased blood flow to the lungs to increase gas ...
Pulmonary fibrosis is a condition in which the lungs become scarred over time. [1] Symptoms include shortness of breath , a dry cough, feeling tired, weight loss, and nail clubbing . [ 1 ] Complications may include pulmonary hypertension , respiratory failure , pneumothorax , and lung cancer .
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.
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 ...
