Oxyhemoglobin

"Blood diluted with water shows the well-known dark bands between D and E, known as the oxyhemoglobin absorption." ❋ Unknown (1908)

The goal of this study is to investigate the incidence of oxyhemoglobin desaturation (OHD) and explore its mechanisms. ❋ Unknown (2010)

Methemoglobinemia is treated with methylene blue which converts methemoglobin to oxyhemoglobin. ❋ Unknown (2010)

This is reflected in a leftward shift of the oxyhemoglobin dissociation curve. 17 Therefore, in cases of methemoglobinemia, a normal pO2 should be expected even in patients with cyanosis. ❋ Unknown (2010)

Functional magnetic resonance imaging (fMRI) (functional brainscanning), a variant of MRI, is based on the fact that oxyhemoglobin, the oxygen-carrying form of hemoglobin, has a different magnetic resonance signal than deoxyhemoglobin, the oxygen-depleted form of hemoglobin. ❋ Unknown (2008)

Activated brain areas utilize more oxygen, which transiently decreases the levels of oxyhemoglobin and increases the levels of deoxyhemoglobin, and within seconds the brain microvasculature responds to the local change by increasing the flow of oxygen-rich blood into the active area. ❋ Unknown (2008)

This local response thus leads to an increase in the oxyhemoglobin-deoxyhemoglobin ratio, which forms the basis for the fMRI signal in the fMRI technique. ❋ Unknown (2008)

And, just like the pulse-ox's SpO2 readout is just a proxy for oxyhemoglobin content, an output of carboxyhemoglobin in grams per dL is more reproducible and medically significant than a percentage full disclosure: I've worked with one of these authors, he's the same one who punctured the myth that nail polish tarnishes pulse oximetry readings. ❋ Unknown (2005)

In collaboration with Bohr and K.A. Hasselbalch the influence of the CO2 tension on the oxyhemoglobin dissociation curve of the blood was demonstrated. ❋ Unknown (1967)

The red blood corpuscles were drained of oxygen and now contained hemoglobin itself, not oxyhemoglobin, that bright red combination of hemoglobin and oxygen. ❋ Asimov, Isaac, 1920- (1966)

This discovery is also called the process of creating the compound oxyhemoglobin. ❋ Unknown (2010)

Absorption takes place at these wavelengths, and it decides the ratio of oxyhemoglobin -- hemoglobin loosely combined with oxygen to deoxyhemoglobin. ❋ Unknown (2010)

When oxyhemoglobin releases O2 in the cells of the body, the quaternary structure undegoesa change. ❋ Ashcraft (2010)

When oxyhemoglobin releases O2 in the cells of the body, the quaternary structure protein showing various subunits ❋ Ashcraft (2010)

The presence of the iron allows oxygen binding and transportation in the form of oxyhemoglobin during cellular respiration. ❋ Ashcraft (2010)
