The compound formed when a molecule of hemoglobin binds with a molecule of oxygen. In vertebrate animals, oxyhemoglobin forms in the red blood cells as they take up oxygen in the lungs.

Automated oxyhemoglobin dissociation curve construction to assess sickle cell anemia therapy.
Near infrared spectroscopy (NIRS) is a non-invasive technique that measures changes in absorption of near infrared light by oxyhemoglobin and deoxyhemoglobin to determine the change of total hemoglobin (tHb) and tissue oxygen saturation (S[O.sub.2]) in a muscle over a period of time.
In the hyperacute and acute phase, the presence of oxyhemoglobin in the hematoma produces an isointense signal on T1-weighted images and a hyperintense signal on T2-weighted images (3).
The upper airway collapse that occurs is associated with episodes of fragmented sleep and repeated decreases in oxyhemoglobin saturation.
Besides, it estimates only oxyhemoglobin and reduced hemoglobin.
In comparing patients' extubated awake and deeply anesthetized, no difference in oxyhemoglobin saturation early after tracheal extubation or in the incidence of laryngospasm was detected.
The affinity of CO to hemoglobin is 240-fold that of O2, and the dissociation of carbonyl hemoglobin is only 1/3600 of oxyhemoglobin. As a non-cumulative toxin, CO can be gradually dissociated from carbonyl hemoglobin after contact and treatment, so it has no chronic toxic effects.13-15 Up to now, the pathogenesis for DEACMP remains unclear.
Oxygenated hemoglobin (oxyhemoglobin or Hb[O.sub.2] absorbs more infrared light than red light.
Data including pH, partial pressure of carbon dioxide (pC[O.sub.2]), partial pressure of oxygen (p[O.sub.2]), bicarbonate (HC[O.sub.3]), base excess (BE), and oxyhemoglobin saturation ([O.sub.2] saturation) were recorded.
The HVR also causes a decrease in the partial pressure of carbon dioxide (PaCO2); the resulting respiratory alkalosis causes a leftward shift of the oxyhemoglobin dissociation curve, which improves alveolar oxygen uptake and, to a lesser degree, reduces oxygen delivery to the tissues.
The researchers found that oxidation of ferrous plasma oxyhemoglobin to ferric methemoglobin was associated with reduced postoperative acute kidney injury from 64 percent in the control group to 50 percent in the treatment group.
