  2. 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).

  3. 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

  4. 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 .

  5. Methemoglobinemia - Wikipedia

    en.wikipedia.org/wiki/Methemoglobinemia

    The SaO2 calculation in the arterial blood gas analysis is falsely normal, as it is calculated under the premise of hemoglobin either being oxyhemoglobin or deoxyhemoglobin. However, co-oximetry can distinguish the methemoglobin concentration and percentage of hemoglobin. [ 3 ]

    The USMLE parent organizations, including the AAFP, AMSA, [29] and AAMC wrote letters to the USMLE recommended broad, systemic changes to the medical program including changing Step 1 to Pass/Fail. "The current overemphasis on USMLE Step 1 is having an overwhelmingly negative impact on students. This should be addressed immediately.

  9. Arterial blood gas test - Wikipedia

    en.wikipedia.org/wiki/Arterial_blood_gas_test

    An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle , [ 1 ] but sometimes the femoral artery in the groin or another site is used.
