  2. Oxygen–hemoglobin dissociation curve - Wikipedia

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

    Specifically, the oxyhemoglobin dissociation curve relates oxygen saturation (SO 2) and partial pressure of oxygen in the blood (PO 2), and is determined by what is called "hemoglobin affinity for oxygen"; that is, how readily hemoglobin acquires and releases oxygen molecules into the fluid that surrounds it. Structure of oxyhemoglobin

  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. Photoacoustic microscopy - Wikipedia

    en.wikipedia.org/wiki/Photoacoustic_microscopy

    Visible light absorbers (λ = 400 to 700 nm) include oxyhemoglobin, deoxyhemoglobin, melanin, and cytochrome c. Visible light photoacoustic microscopy is particularly useful in determining hemoglobin concentration and oxygen saturation due to the difference in absorption profiles of oxyhemoglobin and deoxyhemoglobin.

  5. Multispectral optoacoustic tomography - Wikipedia

    en.wikipedia.org/wiki/Multispectral_optoacoustic...

    The endogenous photoabsorbers most often imaged are oxy- and deoxy-hemoglobin, key players in oxygen metabolism, myoglobin, lipids, melanin and water. Several exogenous contrast agents have also been used in MSOT, including some common histology dyes, fluorescent dyes, novel metal-based agents and non-metallic nanoparticles . [ 2 ]

  6. Functional near-infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Functional_near-infrared...

    The signal is often compared with the BOLD signal measured by fMRI and is capable of measuring changes both in oxy- and deoxyhemoglobin concentration, [2] but can only measure from regions near the cortical surface. fNIRS may also be referred to as Optical Topography (OT) and is sometimes referred to simply as NIRS.

  8. Hematocrit - Wikipedia

    en.wikipedia.org/wiki/Hematocrit

    The hematocrit (/ h ɪ ˈ m æ t ə k r ɪ t /) (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, [1] [2] measured as part of a blood test. [3] The measurement depends on the number and size of red blood cells. [3] It is normally 40.7–50.3% for males and 36.1–44.3% for ...
