n
(Biochemistry) biochem the bright red product formed when oxygen from the lungs combines with haemoglobin in the blood
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.oxyhaemoglobin - the bright red hemoglobin that is a combination of hemoglobin and oxygen from the lungs; "oxyhemoglobin transports oxygen to the cells of the body"
haemoglobin, Hb, hemoglobin - a hemoprotein composed of globin and heme that gives red blood cells their characteristic color; function primarily to transport oxygen from the lungs to the body tissues; "fish have simpler hemoglobin than mammals"

At the completion of the warm-up, participants stood quietly on the treadmill for 7 min and were instrumented with the near-infrared spectroscopy (NIRS) probe (Oxymon MKIII, Artinis, Netherlands) to assess changes in the concentrations of total haemoglobin ([DELTA][THb]), oxyhaemoglobin ([DELTA][[O.sub.2]Hb]) and deoxyhaemoglobin ([DELTA][HHb]) in cerebral tissue.
[10-12,24] Oxygenated blood (oxyhaemoglobin) and deoxygenated blood (deoxyhaemoglobin) differ in their absorption spectra.
Continuous monitoring of cardiac rhythm, heart rate, respiratory rate, oxyhaemoglobin saturation and blood pressure is usually done after the procedure until the effects of sedation and upper airway anaesthesia have been resolved.
Furthermore, [Pb.sup.2+] effect may be seen in the increased production of reactive oxygen species (ROS) by accelerating of oxidation of oxyhaemoglobin to methaemoglobin and thus induces oxidative stress by generating imbalance between production of free radicals in tissues and cellular components and their ability to detoxify the extremely reactive intermediates that causing damage to membranes, DNA and proteins [1].
Recording of the oxyhaemoglobin saturation (Sa[O.sub.2]) and duration of saturation below 90% Sp[O.sub.2] (minutes) were obtained.
Obstructive sleep apnea syndrome (OSAS) is characterized by recurrent episodes of partial or complete collapse of the upper airway during sleep, leading to oxyhaemoglobin desaturation, frequent arousals, and sleep fragmentation [1].
Another study by Watmough in 1982 [27] showed that due to the associated angiogenesis that supplies oxygen and nutrients to cancer cells, optical images of breast cancer can be seen when red blood cells (oxyhaemoglobin) absorb light at about 615 nm.
Indeed, patients undergoing RSI may benefit from pre-oxygenation to increase the oxygen reservoir in the lungs to reduce intubation-related oxyhaemoglobin desaturation (5).
