Cellular toxicity
The cellular toxicity was a measurement of the pathogenic, toxic alteration of the s when lacking oxygen.

In 2371, the cellular toxicity of Neelix went over 86 percent due to his removed lungs. His body could not oxygenate and remove wastes from his bloodstream. The Doctor activated the holographic program Neelix One and took him off the blood-gas infuser. The generated holographic lungs were working and the cellular toxicity was dropping. ()
