  2. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    The oxyhemoglobin has significantly lower absorption of the 660 nm wavelength than deoxyhemoglobin, while at 940 nm its absorption is slightly higher. This difference is used for the measurement of the amount of oxygen in a patient's blood by an instrument called a pulse oximeter .

  3. Blood-oxygen-level-dependent imaging - Wikipedia

    en.wikipedia.org/wiki/Blood-oxygen-level...

    Other methods which propose to measure neural activity directly have been attempted (for example, measurement of the Oxygen Extraction Fraction, or OEF, in regions of the brain, which measures how much of the oxyhemoglobin in the blood has been converted to deoxyhemoglobin [3]), but because the electromagnetic fields created by an active or ...

  4. Oxygen–hemoglobin dissociation curve - Wikipedia

    en.wikipedia.org/wiki/Oxygen–hemoglobin...

    The oxygen–hemoglobin dissociation curve, also called the oxyhemoglobin dissociation curve or oxygen dissociation curve (ODC), is a curve that plots the proportion of hemoglobin in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis. This curve is an important tool for ...

  5. Haldane effect - Wikipedia

    en.wikipedia.org/wiki/Haldane_effect

    In the oxygen-rich capillaries of the lung, this property causes the displacement of carbon dioxide to plasma as low-oxygen blood enters the alveolus and is vital for alveolar gas exchange. The general equation for the Haldane Effect is: H + + HbO 2 ⇌ H + Hb + O 2; However, this equation is confusing as it reflects primarily the Bohr effect.

  6. Haemodynamic response - Wikipedia

    en.wikipedia.org/wiki/Haemodynamic_response

    The most common functional imaging signal is the blood-oxygen-level dependent signal (BOLD), which primarily corresponds to the concentration of deoxyhemoglobin. [13] The BOLD effect is based on the fact that when neuronal activity is increased in one part of the brain, there is also an increased amount of cerebral blood flow to that area which ...

  7. CO-oximeter - Wikipedia

    en.wikipedia.org/wiki/CO-oximeter

    Finger tip carboxyhemoglobin saturation monitor.. A CO-oximeter is a device that measures the oxygen carrying state of hemoglobin in a blood specimen, including oxygen-carrying hemoglobin (O2Hb), non-oxygen-carrying but normal hemoglobin (HHb) (formerly, but incorrectly, referred to as 'reduced' hemoglobin), as well as the dyshemoglobins such as carboxyhemoglobin (COHb) and methemoglobin (MetHb).

    For the 12th consecutive quarter, Best Buy posted negative same-store sales growth. Net sales and earnings per share also missed estimates.

  9. Hemocyanin - Wikipedia

    en.wikipedia.org/wiki/Hemocyanin

    The study compared oxyhemocyanin levels in the blood of white shrimp housed in an indoor pond with a commercial diet with that of white shrimp housed in an outdoor pond with a more readily available protein source (natural live food) as well. Oxyhemocyanin and blood glucose levels were higher in shrimp housed in outdoor ponds.
