If the engine has recently had cylinder head gasket damage, the O2 sensors may need to be replaced due to contamination. A good O2 sensor should exhibit high switching activity, with readings ranging from volts or less to volts. If the sensor is sluggish or shows a low level, it should be replaced.
Test for carbon dioxide
A CO2 blood test measures the amount of carbon dioxide (CO2) in your blood serum, the liquid part of your blood. The CO2 test can also be called - you can take the CO2 test as part of the metabolic panel. The metabolic panel is a group of tests that measure electrolytes and gases in the blood. There are two main forms of CO2 in the body:.
What are the tests used to identify carbon dioxide?
There are two tests for carbon dioxide. The flame is extinguished first, but since any gas without oxygen will also extinguish the flame, this is a bad gas test and can lead to misidentification. The best way to test for carbon dioxide is with bubbles in the lime water. A positive test result makes lime water milky.

High CO2 levels indicate breathing problems such as emphysema, asthma or sleep apnea.
What does high CO2 blood test result mean?
High levels of CO2 in the blood. A condition associated with high levels of carbon dioxide (CO2) in the blood is called hypercapnia. This may be due to a low level of oxygen in the blood, which is called hypoxia. Medical intervention is necessary if there is a clear imbalance in the levels of CO2 and O2 in the blood.
What are the symptoms of too much CO2?
Symptoms of excess carbon dioxide in the blood include dizziness, nausea, vomiting, headache, shortness of breath and fatigue. Blood gas measurements may also be taken in people with breathing problems or problems with normal kidney function.
