n.
A bright-red chemical complex of hemoglobin and oxygen that transports oxygen to the tissues.

oxyhemoglobin  (ks-hm-glbn)
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. See Note at hemoglobin.

Impact of oxyhemoglobin dissociation curve Hypoxemic patients at baseline (as measured by PaO2) are more likely to drop their SaO2 with hypoventilation during sleep, compared to normoxic patients at baseline due to the effect of the oxyhemoglobin dissociation curve 23.
The result is a leftward shift of the oxyhemoglobin dissociation curve, and a compromised tissue O2 delivery.
2] delivery occurs from two mechanisms: 1) metHb is incapable of carrying oxygen, and 2) metHb shifts the oxyhemoglobin dissociation curve to the left, thereby further decreasing [O.
