Definition of Oxyhemoglobin - MedicineNet
https://www.medicinenet.com/oxyhemoglobin/definition.htm
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.

Misconceptions in reporting oxygen saturation
https://pubmed.ncbi.nlm.nih.gov/18048899/
In 1980, oxygen saturation was incorrectly redefined in a report of a new instrument for analysis of hemoglobin (Hb) derivatives. Oxygen saturation (sO2) was redefined as the ratio of oxyhemoglobin (O2Hb) to total Hb instead of the ratio of O2Hb to active Hb (O2Hb + desoxyhemoglobin).

Changes in Oxyhemoglobin Concentration in the Prefrontal ...
https://www.ncbi.nlm.nih.gov/pubmed/28685452
The present study investigated whether changes in oxyhemoglobin (O2Hb) concentration over time differed across brain regions according to differences in gross movement intensity. Thirteen healthy adults (21.2 ± 1.0 years, 8 women) participated in this study. After 180 s of rest, the participants performed 600 s of exercise on a cycle ergometer.

Fraction of oxygenated haemoglobin | Deranged Physiology
https://derangedphysiology.com/main/cicm-primary-exam/required-reading/respiratory-system/Chapter%201112/fraction-oxygenated-haemoglobin
The fraction of oxygenated haemoglobin is a parameter which is calculated from values directly measured by absorption spectrophotometry. It is expressed as FO2Hb. As you can see, oxygen saturation and the fraction of oxygenated haemoglobin are not interchangeable.

Oxygen-Haemoglobin Dissociation Curve • LITFL • CCC ...
https://litfl.com/oxygen-haemoglobin-dissociation-curve/
sigmoid shape of the oxy-Hb dissociation curve results from the allosteric interactions of the globin monomers that make up the haemoglobin tetramer as each one binds O2. Multiple factors can affect the affinity of Hb for oxygen, thus causing the curve to shift to the left (increased oxygen affinity) or to the right (decreased O2 affinity)

LOINC 24339-4 — Gas panel - Venous blood
https://loinc.org/24339-4/
Hemoglobin oxygen saturation = is the amount of oxyhemoglobin expressed as the percent of the hemoglobin able to bind oxygen, i.e. oxyhemoglobin (O2Hb) + deoxyhemoglobin (HHb). sO2 = 100 x O2Hb/ (O2Hb + HHb)

1. Fractional oxyhemoglobin, FO 2 Hb, is defined as the fraction of oxygenated hemoglobin in relation to the total of all hemoglobins present (including the non-oxygen binding dyshemoglobins) FO 2 Hb = cO 2 Hb = ctHb cO 2 Hb cO 2 Hb + cHHb + cCOHb + cMetHb . 2.

Oxygen–hemoglobin dissociation curve - Wikipedia
https://en.wikipedia.org/wiki/Oxygen%E2%80%93hemoglobin_dissociation_curve
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.

What Pulse Oximeter Measure, Normal Range - Health Jade
https://healthjade.net/oximeter/
Oxyhemoglobin (O2Hb) absorbs greater amounts of infrared light and lower amounts of red light than does deoxyhemoglobin (HHb); this is consistent with experience – well-oxygenated blood with its higher concentrations of oxyhemoglobin (O2Hb) appears bright red to the eye because it scatters more red light than does deoxyhemoglobin (HHb).
