Definition of Oxyhemoglobin - MedicineNet
Oxyhemoglobin: The oxygen-loaded form of hemoglobin, the predominant protein in red blood cells. Hemoglobin is a protein molecule that binds to oxygen. Hemoglobin forms an unstable, reversible bond with oxygen. In its oxygen-loaded form, it is called oxyhemoglobin and is bright red.

Oxyhemoglobin - an overview | ScienceDirect Topics
Michael J. Krowka, in Reference Module in Biomedical Sciences, 2019. Screening for Hypoxemia. Oxyhemoglobin saturation (SaO 2) measured by finger pulse oximetry, and arterial l blood gas assessments of the arterial partial pressure of oxygen (PaO 2) and the alveolar-arterial (A-a) oxygen gradient are different means to characterize the degree of arterial hypoxemia in patients with liver disease.

Laboratory Assessment of Oxygenation in Methemoglobinemia ...
The fractional oxyhemoglobin can only be measured by a multiwavelength spectrophotometer such as a CO-oximeter. The FO 2 Hb represents the fraction of oxyhemoglobin in relation to the total hemoglobin (tHb) present (including the non-oxygen-binding hemoglobins). The fraction of any of the hemoglobin derivatives may be calculated in the same manner.

Decoding the oxyhemoglobin dissociation curve
The normal oxyhemoglobin dissociation curve (OHDC), shown here by the solid blue line, indicates that when the partial pressure of arterial oxygen (Pa O2) is 40 mm Hg, oxy - gen saturation of hemoglobin (Sa O2) is 75%. At the tissue or capillary level, a Pa O2of 40 mm Hg is normal. At this point, about 25% of the oxygen carried on hemoglobin from

Blood Gas Panel | Test Detail | Quest Diagnostics
Blood Gas Panel - Cardiac catheterization laboratories and intensive care units routinely use oxyhemoglobin saturation (%HBO2) total hemoglobin (THB), and oxygen content (O2C) for 2 purposes: 1) To detect intracardiac and great vessel shunts 2) Compute cardiac output by the fick principle

Hemoglobin - Wikipedia
Hemoglobin (American English) or haemoglobin (British English) (Greek αἷμα (haîma, “blood”) + -in) + -o- + globulin (from Latin globus (“ball, sphere”) + -in) (/ ˈ h iː m ə ˌ ɡ l oʊ b ɪ n, ˈ h ɛ-,-m oʊ-/), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells (erythrocytes) of almost all vertebrates (the exception being the ...

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 ...
