ox·y·he·mo·glo·bin

(ok'sē-hē'mŏ-glō'bin)
Hemoglobin in combination with oxygen; the form of hemoglobin present in arterial blood, scarlet or bright red when dissolved in water.
Synonym(s): oxyhaemoglobin.

oxyhaemoglobin

The bright red, oxygenated form of HAEMOGLOBIN in the red blood cells, in which a molecule of oxygen has attached itself reversibly to the iron atom in the haemoglobin molecule. Oxyhaemoglobin transports oxygen from the lungs to the tissues.

oxyhaemoglobin

HAEMOGLOBIN that is oxygenated.

ox·y·he·mo·glo·bin

(ok'sē-hē'mŏ-glō'bin)

Subjects with higher FRS had a larger neck circumference (40.48 [+ or -] 2.80 versus 39.15 [+ or -] 4.31 cm, p < 0.05), longer course of disease (12.77 [+ or -] 7.89 versus 9.36 [+ or -] 5.98 years, p < 0.05), increased AHI (47.61 [+ or -] 25.63 versus 34.01 [+ or -] 25.72 events/h, p < 0.01), lower minimum oxyhaemoglobin saturation during sleep (73.85 [+ or -] 11.10 versus 77.91 [+ or -] 9.77%, p < 0.05), longer time with oxyhaemoglobin saturation <90% (23.46 [+ or -] 24.46 versus 14.48 [+ or -] 18.85%, p < 0.05), and higher ODI (49.62 [+ or -] 23.75 versus 39.01 [+ or -] 24.87 events/h, p < 0.05) [18].
When oxyhaemoglobin reaches the oxygen-hungry tissues it releases its oxygen.
Compared to non-REM sleep, REM sleep is associated with longer apnoeic episodes and more frequent oxyhaemoglobin desaturation (Findley et al 1985).
(13,14) Central to retinal oximetry is the differing spectral properties of oxyhaemoglobin and deoxyhaemoglobin (see Figure 4).
The concentration changes of oxyhaemoglobin, [DELTA][Hb[O.SUB.2]], and deoxyhaemoglobin, [DELTA][HHb] were then derived with the MLBL.
The first one corresponds mainly to the bilirubin content and the second one to the oxyhaemoglobin content [3].
The mechanism involved in the dramatic increase in oxyhaemoglobin saturation observed after sternotomy is not entirely clear in the absence of more detailed information on pulmonary mechanics and haemodynamics.
Newer, multiple wavelength oximeters can distinguish carboxyhaemoglobin from oxyhaemoglobin, as well as give an indication of the total amount of Hb present.
Oxyhaemoglobin is diamagnetic, while deoxyhaemoglobin is paramagnetic; these different magnetic properties give rise to contrast in magnetic resonance images.
The higher [a.sup.*] values and the lower [L.sup.*] and [b.sup.*] values in the R1 and R4 NMCs are in agreement with a relationship among [a.sup.*] values, red fibre percentages (I-IIa MyHC isoforms) and oxyhaemoglobin values.
An abnormal breathing event during objectively measured sleep was defined according to the common clinical criteria of either a complete cessation of airflow lasting 10 sec (apnoea) or a discernible reduction in airflow accompanied by a decrease of 4 per cent in oxyhaemoglobin saturation (hypopnoea).The average number of episodes of apnoea and hypopnoea per hour of sleep, the apnoea hypopnoea index (AHI) was calculated.
