Sevoflurane also affects the respiratory system. It causes a relaxation of the muscles in the airways, which can lead to a decrease in respiratory effort. To counteract this effect, patients are typically provided with mechanical ventilation, where a ventilator assists with breathing throughout the surgery. This ensures that the patient receives enough oxygen and expels carbon dioxide efficiently.
The pH level of water can significantly impact its chemistry and usability. In many cases, it is necessary to adjust the pH to neutral levels for optimal treatment and safety. Chemicals like sulfuric acid or sodium hydroxide are commonly used for this purpose. By balancing the pH, water becomes less corrosive and more effective for disinfection processes. This adjustment also helps in preventing the leaching of heavy metals from distribution pipes, thereby protecting water quality.

The mechanism by which NMU induces mutations is primarily through its alkylating properties. Upon exposure, NMU can add alkyl groups to DNA bases, leading to mispairing during DNA replication. This results in transitions or transversions in the nucleotide sequence, which can ultimately lead to permanent mutations. If these mutations occur in critical genes responsible for regulating cell growth and division, such as proto-oncogenes and tumor suppressor genes, they may lead to uncontrolled cell proliferation and cancer.
