CO2, brainstem chemoreceptors and breathing

The regulation of breathing relies upon chemical feedback concerning the levels of CO2 and O2. The carotid bodies, which detect O2, provide tonic excitation to brainstem respiratory neurons under normal conditions and dramatic excitation if O2 levels fall. Feedback for CO2 involves the carotid body …

How does an NDIR CO2 Sensor Work? |

Today's newest generation of CO2 sensors has even more optimized waveguides, allowing a longer optical light path to be folded into an even smaller. 8 mm x 33 mm x 20 mm footprint. In addition to a smaller size, new mid-range infrared light-emitting diode (LED) light sources have been developed that allow NDIR sensors to operate at much lower power levels. Combined with a photo-diode light ...

How Inhaled Carbon Dioxide Affects the Body Fact Sheet

in each breath is ~%, and the “average” person produces approximately two pounds of carbon dioxide each day. More CO 2 is given off by strenuous activity. Hypercapnia, hypercarbia, or hypercapnea, is the physiological term for the condition of, and the body’s response to, excessive carbon dioxide. When CO 2 is breathed into the lungs, it dissolves in the water there, diffuses across ...
