Definition. CO2 is carbon dioxide. This article discusses the laboratory test to measures the amount of carbon dioxide in the liquid part of your blood, called the serum.

Potassium can cause stomach upset, nausea, diarrhea, vomiting, intestinal gas, and other side effects. Too much potassium is UNSAFE and can cause feelings of burning or tingling, generalized weakness, paralysis, listlessness, dizziness, mental confusion, low blood pressure, irregular heart rhythm, and death.
As kidneys become less able to remove potassium from your blood, too much potassium may build up. Often, like high blood pressure, there arenât many symptoms of high potassium (hyperkalemia). Feeling sick to your stomach, a low, weak or irregular pulse and fainting may occur with high levels of potassium. Consult with a healthcare professional before taking any over-the-counter potassium supplement.
