  2. Oxygen–hemoglobin dissociation curve - Wikipedia

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

    The T state has a lower affinity for oxygen than the R state, so with increased acidity, the hemoglobin binds less O 2 for a given P O2 (and more H +). This is known as the Bohr effect . [ 4 ] A reduction in the total binding capacity of hemoglobin to oxygen (i.e. shifting the curve down, not just to the right) due to reduced pH is called the ...

  3. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    The Bohr effect favors the T state rather than the R state. (shifts the O 2-saturation curve to the right). Conversely, when the carbon dioxide levels in the blood decrease (i.e., in the lung capillaries), carbon dioxide and protons are released from hemoglobin, increasing the oxygen affinity of the protein.

  4. Bohr effect - Wikipedia

    en.wikipedia.org/wiki/Bohr_effect

    In the R state, the ionic pairings are absent, meaning that the R state's stability increases when the pH increases, as these residues are less likely to stay protonated in a more basic environment. The Bohr effect works by simultaneously destabilizing the high-affinity R state and stabilizing the low-affinity T state, which leads to an overall ...

  5. Fick principle - Wikipedia

    en.wikipedia.org/wiki/Fick_principle

    Measuring the content of hemoglobin in the blood and the percentage of saturation of hemoglobin (the oxygen saturation of the blood) is a simple process and is readily available to physicians. Using the fact that each gram of hemoglobin can carry 1.34 mL of O 2 , the oxygen content of the blood (either arterial or venous) can be estimated by ...

  6. Red blood cell indices - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell_indices

    Mean corpuscular volume (MCV) is the average volume of a red blood cell and is calculated by dividing the hematocrit (Hct) by the concentration of red blood cell count. [citation needed] = [] Normal range: 80–100 fL (femtoliter)

  7. Near-infrared window in biological tissue - Wikipedia

    en.wikipedia.org/wiki/Near-infrared_window_in...

    In addition to the total concentration of hemoglobin, the oxygen saturation will define the concentration of oxy- and deoxyhemoglobin in tissue and so the total absorption spectrum. Depending on the type of tissue, we can consider different situations. Below, the total concentration of hemoglobin is assumed to be 2.3 mM.

    For example, Erivo tried on multiple versions of Elphaba's hat before settling on the one she liked best. Ariana Granda is Glinda in "Wicked," holding the hat Erivo chose for her character.

  9. 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).
