hy·pox·e·mi·a

(hī'pok-sē'mē-ă)
Subnormal oxygenation of arterial blood, short of anoxia.
Synonym(s): hypoxaemia.
[hypo- + oxygen, + G. haima, blood]

hypoxaemia

Deficiency of oxygen in the blood. This is usually due to relative failure of the passage of oxygen from the atmosphere to the blood because of lung disease, or inadequate or inappropriate movement of blood through the lungs because of heart disease, either congenital or acquired. Hypoxaemia often causes CYANOSIS.

hypoxaemia

lower than normal oxygen tension ( P O2) in the arterial blood, therefore lower than normal saturation of haemoglobin and oxygen content per unit volume. See also oxyhaemoglobin dissociation curve.

In our studies, 16% of patients have pulse oximetry evidence of hypoxaemia.
The risk of serious adverse outcomes associated with hypoxaemia and hyperoxaemia in acute exacerbations of COPD.
Patients with EF <50% present with higher levels of CRP and fibrinogen and have a 3-fold increased risk for hospital mortality that is independent of age and levels of hypoxaemia and pro-inflammatory biomarkers.
Hypothermia, acidosis, polycythaemia, hypoglycaemia, hypocalcaemia and hypomagnesaemia should be corrected appropriately) [3,10] Correction of acidosis with controlled alkalosis using an alkali infusion and hyperventilation is no longer advocated due to the association with sensorineural hearing loss and impaired cerebral perfusion) [3,10] Minimal handling and judicious sedation is advised to avoid labile hypoxaemia.
In Australia the guidelines for the management of LTOT recommend that it is prescribed for at least 18 hours per day and it has been found to be the only component in the management of COPD patients with severe daytime hypoxaemia that improves survival, quality of life and reduces mortality (McDonald et al 2014).
This V/Q mismatch triggers responses that reduce ventilation and increase cardiac output, actually worsening the hypoxaemia.
The associated chronic fetal hypoxaemia results in redistribution of blood flow in favour of vital organs including the brain, initially characterised by decreasing MCA impedance due to increasing vasodilatation with worsening hypoxaemia.
4%) children needed hospitalization during the follow-up period due to severe pneumonia with hypoxaemia (n = 5), ventricular septal defect (VSD) with cyanosis (n = 2), pulmonary tuberculosis (n = 1), severe pallor (n = 1), vesical calculus (n = 1), and severe pneumonia with SAM (n = 1) (Figure).
1) Most patients demonstrate impaired gas exchange, as evidenced by low oxygen-haemoglobin saturation at rest or on exercise; hypoxaemia on arterial blood gas sampling; or impaired diffusing capacity (DLCO).
The effects of ageing, smoking and hypoxaemia on brain function are likely to contribute to its genesis.

Three days later, he was transferred to the ICU at our hospital with severe hypoxaemia and a clinical presentation suggestive of septic shock.
