The Claim
An increase in temperature from 26°C to 42°C results in a 7% increase in the apparent buffering value of deoxygenated human whole blood for CO2 relative to its value at 26°C, although this change is not statistically significant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When deoxygenated human blood is heated from 26°C to 42°C, its ability to buffer carbon dioxide increases by 7% compared to its buffering capacity at 26°C, but this change is not statistically significant.
See the scientific wording
When temperature increases from 26°C to 42°C, the apparent buffering value of deoxygenated human whole blood for CO2 increases by 7% of its value at 26°C, though this change is not statistically significant, suggesting limited capacity for temperature-driven changes in CO2 buffering under low oxygen conditions.
When blood gets warmer, the shape of hemoglobin changes slightly when it is not carrying oxygen, making it hold onto carbon dioxide more tightly, which allows the blood to absorb a little more carbon dioxide.
What the research says
1 studyStudy: The apparent buffer value of human blood for CO2 as a function of temperature.
When blood with little oxygen gets warmer, it can absorb a little more carbon dioxide — about 7% more — but the change is so small that scientists can’t be sure it’s real. The study confirms this exact finding.
