Arterial Oxygen Content Solution

STEP 0: Pre-Calculation Summary

Formula Used

Arterial Oxygen Content = (Hemoglobin*1.36*SaO2/1000)+(0.0031*PaO2 (mm/Hg))
CaO2 = (Hb*1.36*SaO2/1000)+(0.0031*PaO2)
This formula uses 4 Variables

Variables Used

Arterial Oxygen Content - The arterial oxygen content is the amount of oxygen bound to hemoglobin plus the amount of oxygen dissolved in arterial blood.
Hemoglobin - (Measured in Kilogram per cubic meter) - Hemoglobin is the oxygen-carrying pigment and predominant protein in the red blood cells.
SaO2 - SaO2 is the percentage of hemoglobin saturated with oxygen.
PaO2 (mm/Hg) - PaO2 (mm/Hg) is the arterial oxygen partial pressure.

STEP 1: Convert Input(s) to Base Unit

Hemoglobin: 13 Grams per Deciliter --> 130 Kilogram per cubic meter (Check conversion here)
SaO2: 95 --> No Conversion Required
PaO2 (mm/Hg): 85 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

CaO2 = (Hb*1.36*SaO2/1000)+(0.0031*PaO2) --> (130*1.36*95/1000)+(0.0031*85)

Evaluating ... ...

CaO2 = 17.0595

STEP 3: Convert Result to Output's Unit

17.0595 --> No Conversion Required

FINAL ANSWER

17.0595 <-- Arterial Oxygen Content

What is Arterial Oxygen Content?

Arterial blood oxygen content (CaO2) is measured by a co-oximeter after anaerobic collection of a heparinized arterial blood sample and is the sum of oxygen bound to hemoglobin and oxygen carried in physical solution in the blood. The equipment required to determine CaO2 requires frequent calibration and provides little additional information other than that produced by measuring hemoglobin concentration and PaO2. Arterial oxygen content depends on the concentration of hemoglobin and the binding affinity or degree of oxygen saturation (SaO2) of the hemoglobin present. The majority of arterial oxygen is delivered to tissues while bound to hemoglobin while a small fraction is dissolved in plasma.

How to Calculate Arterial Oxygen Content?

Arterial Oxygen Content calculator uses Arterial Oxygen Content = (Hemoglobin*1.36*SaO2/1000)+(0.0031*PaO2 (mm/Hg)) to calculate the Arterial Oxygen Content, The arterial oxygen content is the amount of oxygen bound to hemoglobin plus the amount of oxygen dissolved in arterial blood. Arterial Oxygen Content is denoted by CaO2 symbol.

How to calculate Arterial Oxygen Content using this online calculator? To use this online calculator for Arterial Oxygen Content, enter Hemoglobin (Hb), SaO2 (SaO2) & PaO2 (mm/Hg) (PaO2) and hit the calculate button. Here is how the Arterial Oxygen Content calculation can be explained with given input values -> 17.0595 = (130*1.36*95/1000)+(0.0031*85).

FAQ

What is Arterial Oxygen Content?

The arterial oxygen content is the amount of oxygen bound to hemoglobin plus the amount of oxygen dissolved in arterial blood and is represented as CaO2 = (Hb*1.36*SaO2/1000)+(0.0031*PaO2) or Arterial Oxygen Content = (Hemoglobin*1.36*SaO2/1000)+(0.0031*PaO2 (mm/Hg)). Hemoglobin is the oxygen-carrying pigment and predominant protein in the red blood cells, SaO2 is the percentage of hemoglobin saturated with oxygen & PaO2 (mm/Hg) is the arterial oxygen partial pressure.

How to calculate Arterial Oxygen Content?

The arterial oxygen content is the amount of oxygen bound to hemoglobin plus the amount of oxygen dissolved in arterial blood is calculated using Arterial Oxygen Content = (Hemoglobin*1.36*SaO2/1000)+(0.0031*PaO2 (mm/Hg)). To calculate Arterial Oxygen Content, you need Hemoglobin (Hb), SaO2 (SaO2) & PaO2 (mm/Hg) (PaO2). With our tool, you need to enter the respective value for Hemoglobin, SaO2 & PaO2 (mm/Hg) and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
