The Bohr Effect

Find out more about the Bohr Effect with these YouTube videos. I always like to source multiple opinions so I have included the description from a variety of different teachers.

 The Bohr effect is a physiological phenomenon first described in 1904 by the Danish physiologist Christian Bohr, stating that hemoglobin’s oxygen binding affinity is inversely related both to acidity and to the concentration of carbon dioxide. That is to say, a decrease in blood pH or an increase in blood CO2 concentration will result in hemoglobin proteins releasing their loads of oxygen and a decrease in carbon dioxide or increase in pH will result in hemoglobin picking up more oxygen. Since carbon dioxide reacts with water to form carbonic acid, an increase in CO2 results in a decrease in blood pH.

Bohr Effect: Healthy vs. Sick People and Oxygen Transport

The Bohr effect is a part of oxygen transport. The Bohr effect works well in healthy people. Dr. Buteyko found that people with heart disease, diabetes and many other problems suffer from low cells oxygenation due to the reduced Bohr effect caused by their deep breathing. This effect explains why sick people breathe more air (hyperventilation), but have less oxygen delivered to their cells of all vital organs…

The Bohr Effect

In this video, Leslie talks about the bohr effect, showing how a combination of an increase in CO2 production, combined with a reduction in pH results in an increase in Oxygen delivery by Hemoglobin.
