The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of oxygen, but also of carbon dioxide.Furthermore, it is also sensitive to changes in pH and temperature.he output of the carotid bodies is low at an oxygen partial pressure above about 100mmHg (13,3 k Pa) (at normal physiological pH), but below 60mmHg the activity of the type I (glomus) cells increases rapidly due to a decrease in hemoglobin-oxygen saturation below 90%.
