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.

oxyhaemoglobin

oxygenated haemoglobin, e.g. arterial blood

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.
Synonym(s): oxyhaemoglobin.

For the purpose of retinal oximetry, this requires the measurement of light absorption at a minimum of two wavelengths to determine the relative concentrations of oxyhaemoglobin and deoxyhaemoglobin, and, therefore, enabling the oxygen saturation of a blood vessel to be determined.
Gastric mucosal NOS activity was measured spectrophotometrically using the oxidation of oxyhaemoglobin to methaemoglobin by NO as described previously (Knowles et al.
The absorption of oxyhaemoglobin and deoxyhaemoglobin at these two wavelengths is very different.
Three-dimensional fourier synthesis of horse oxyhaemoglobin at 2.
The level of oxygen in the blood is calculated from the ratio of absorbed red to infrared light using the ratio of oxyhaemoglobin to the sum of all the functional haemoglobin.
In severely anaemic patients, CT may miss a haemorrhagic lesion due to low oxyhaemoglobin.
Maximal or minimum values during the exercise period were used to determine absolute concentration changes for deoxyhaemoglobin ([DELTA]HHb), oxyhaemoglobin (DELTA]O2Hb), total haemoglobin (DELTA]cHb), and tissue oxygenation index (TOI, the ratio of oxygenated to total tissue haemoglobin) and normalised tissue haemoglobin index (nTHI, the relative concentration of total haemoglobin).
When oxyhaemoglobin reaches the body's oxygen-hungry tissues, it then releases its oxygen.
1) Since then, near-infrared spectroscopy (NIRS) has been used to monitor oxyhaemoglobin, deoxyhaemoglobin, blood volume and cytochrome oxidase for a variety of clinical and research applications.
Hypopnoea was defined as a discernible reduction in respiratory airflow during a preceding period of normal breathing for [greater than or equal to] 10 sec accompanied by a decrease of 4 per cent or more in oxyhaemoglobin saturation during sleep.
Sleep Disordered Breathing (SDB) is characterized by repetitive upper airway obstruction and consequent oxyhaemoglobin desaturation during deep stages of sleep.
Blood pressure was monitored non-invasively every five minutes throughout surgery and heart rate via electrocardiogram and oxyhaemoglobin saturation (pulse oximetry) monitored continuously.
