You may start to feel dizzy and/or weak. Then if you don't get help or emergency attention and the level of CO2 is far higher than the oxygen level, you can pass out.
The atmospheric temperature will decrease
Chemoreceptors detect the levels of carbon dioxide in the blood.
Any time you use electricity you contribute to carbon dioxide levels in the atmosphere, as most electricity is generated by burning fossil fuels. This also happens when you drive a vehicle, or fly in a plane.
This is respiratory acidosis. The patient will be unable to perform proper gas exchange due to the obstruction (food). As a result, the carbon dioxide levels will rise, and the pH will drop.
In the mid-1700s the levels of carbon dioxide in the atmosphere were about 280 ppm (parts per million).In 2004 the levels of carbon dioxide in the atmosphere were about 375 ppm.In 2012 the levels of carbon dioxide in the atmosphere were about 393 ppm.
blood carbon dioxide levels
Acute respiratory failure with high carbon dioxide levels
Respiratory system
Primarily it is the cabon dioxide levels that trigger respiratory drive, however in some disease states such as COPD increased oxygen levels can decrease respiratory drive.
Respiratory system
Carbon dioxide levels increas
With increased breathing, levels of carbon dioxide in the blood drop and levels of oxygen rise.
The levels of carbon dioxide in the body are monitored by chemoreceptors, (they do this by measuring pH - lower pH means more carbon dioxide). If the levels of carbon dioxide are too high then the respiratory centre of the brain (in the medulla oblongatis) sends signals to the lungs and diaphragm to increase the breathing rate.

The atmospheric temperature will decrease
eutrophication
Oxygen is very sparingly soluble. Carbon dioxide is highly soluble in water or plasma. The respiratory center is stimulated by high level of the carbon dioxide. The respiratory center probably does not analyse the oxygen level.
