* Oxygen saturation, a relative measure of the oxygen dissolved or carried in a medium ; a measure of the severity of hypoxic conditions.
* Oxygen toxicity ( hyperoxia ), the opposite condition of hypoxia, an excess of oxygen in body tissues.
Oxygen ( O < sub > 2 </ sub >) levels in the exhaust stream were generally insufficient for the catalytic reaction to occur efficiently, so most installations included secondary air injection which injected air into the exhaust stream to increase the available oxygen and allow the catalyst to function.
Oxygen sensors are used to monitor the exhaust oxygen content before and after the catalytic converter and this information is used by the Electronic control unit to adjust the fuel injection so as to prevent the first ( NO < sub > x </ sub > reduction ) catalyst from becoming oxygen-loaded while ensuring the second ( HC and CO oxidization ) catalyst is sufficiently oxygen-saturated.
