The maximum amount of oxygen that can be carried in arterial blood is approximately 20.2 mmol/L. This is equivalent to about 98.5% of the oxygen that is dissolved in the plasma. The remaining 1.5% is bound to hemoglobin and is termed oxyhemoglobin. The amount of oxygen that can be carried by the blood is dependent on the concentration of hemoglobin in the blood as well as the oxygen saturation of hemoglobin. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment which is why the amount of oxygen that can be carried varies in different environments.
The following factors affect the amount of oxygen that can be carried in arterial blood:
- Hemoglobin concentration
- Oxygen saturation of hemoglobin
- Partial pressure of oxygen in the environment
Hemoglobin is a protein in red blood cells that binds to oxygen and carries it throughout the body. The concentration of hemoglobin in the blood is an important factor in determining how much oxygen can be carried. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment. This means that the amount of oxygen that can be carried in the blood varies in different environments. For example in a high-altitude environment where the partial pressure of oxygen is lower the oxygen saturation of hemoglobin is also lower resulting in less oxygen being carried in the blood.

What does arterial mean as in arterial o2 saturations?
Arterial is a reference to the blood in the arteries, as opposed to blood in the veins.
How does emphysema affect arterial blood gases?
O2 sat on room air or arterial blood would be lower than normal. CO2 levels would be higher.
Is capillary blood more like arterial blood than venous blood?
yes bcz O2-bound heamoglobin (called oxyheamoglobin) is bright red in colour.
What are the three types of blood vessels and what type of blood is carried in each?
The three types of blood vessels are: 1. arteries which usually carry O2 blood 2. veins which usually carry low O2 blood 3. capillaries which carry high O2 blood at the begging of the "bed" and low O2 at the end of the "bed"
In what form is o2 carried in blood?
Oxygen is bound to a protein (a respiratory pigment), called hemoglobin.
What purpose do arterial venous lines serve?
Since one of the ideas of an arterial line is to check on blood gases (O2 saturation mainly), placing a line in the pulmonary artery would counteract this idea. Arteries are called such since they carry blood AWAY from the heart, etc.
In PA02 Does the P stand for Pulmonary what is the A I know O2 stand for oxygen please help.?
PaO2 is the partial pressure of oxygen in arterial blood. Pa is the abbreviation of partial.
What does O2 saturation mean?
In medicine it refers to the percent O2 attached to (arterial) hemoglobin as a comparison to the maximum that could be attached. In a healthy person the blood leaving the lungs (and/or the left ventricle) should be 100% (or not less than 99%).
What is the difference between pco2 and paco2?
PCO2 refers to the partial pressure of carbon dioxide in the blood, while PaCO2 specifically refers to the partial pressure of carbon dioxide in arterial blood. Arterial blood is the blood that has been oxygenated in the lungs and is then circulated to the rest of the body. The PaCO2 measurement is more precise and important in clinical assessments compared to just PCO2.
What are the functions of blood in respiration?
Blood in the body carried respiratory gases (i.e. O2 and CO2) around the body to cells where it's needed for cellular respiration.
What carries o2 and co2 in the blood?
Oxygen is carried in the blood by hemoglobin, a protein in red blood cells that binds to oxygen molecules. Carbon dioxide, on the other hand, is carried in the blood in different forms - either dissolved in plasma, bound to hemoglobin, or as bicarbonate ions.
Which blood vessel carries oxygen-rich blood to the body?
Pulmonary veins and systemic arterial system.
