Oxygen–hemoglobin dissociation curve - Wikipedia
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 understanding how our blood carries and releases oxygen.

Oxyhemoglobin | definition of oxyhemoglobin by Medical ...
Since Frans Jobsis first demonstrated the feasibility of monitoring the concentration change of oxyhemoglobin (oxy-Hb) and deoxyhemoglobin (deoxy-Hb) in 1977 , functional near-infrared spectroscopy (fNIRS) is getting more and more attentions in the past 20 years as an effective research and clinical tool [4-7].

Point-of-care hemoglobin testing: Methods and relevance to ...
POC hemoglobin analyzers using reagent-less cuvettes were developed to overcome these limitations. They either measure the absorbance of whole blood photometrically at the isosbestic point—the wavelength in which the absorbance the two main hemoglobin derivatives, oxy-hemoglobin (HbO2) and deoxy-hemoglobin (Hb), is the same—or, more ...

Point-of-Care Tests for Anemia | Labcompare.com
The determination of hemoglobin concentration in this system is based on measuring the absorbance of whole blood at an oxyhemoglobin-deoxyhemoglobin isobestic point. ... Point of care (POC) diagnostic devices are used to obtain diagnostic results while with the patient or close to the patient. Used in …

What is Oxyhemoglobin? (with pictures) - wiseGEEK
Oxyhemoglobin is the form of hemoglobin that carries oxygen. It also causes the blood to be bright red. The hemoglobin of unborn babies has a higher affinity for oxygen than the hemoglobin of the mother. When the oxyhemoglobin reaches the tissues of the body, the oxygen is released into the cells.

Difference Between Oxyhemoglobin and Deoxyhemoglobin ...
The main difference between oxyhemoglobin and deoxyhemoglobin is that the oxyhemoglobin is the form of hemoglobin loosely combined with oxygen whereas the deoxyhemoglobin is the form of hemoglobin that has released its bound oxygen. Furthermore, the oxyhemoglobin is bright red in color while the deoxyhemoglobin is purplish in color. ...

Hemoglobin Test: Normal, High, Low Levels & Results
Hemoglobin (sometimes abbreviated as Hb) is a complex protein found in red blood cells that contains an iron molecule. The main function of hemoglobin is to carry oxygen from the lungs to the body tissues, and to exchange the oxygen for carbon dioxide, and then carry the carbon dioxide back to the lungs and where it is exchanged for oxygen. The iron molecule in hemoglobin helps maintain the ...
