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.
On the other hand, HALS are a unique class of stabilizers that work by scavenging free radicals generated during the photodegradation process. By trapping these free radicals, HALS significantly slow down the degradation of the polymer chains, preserving the mechanical properties of the plastic. This mechanism allows HALS to be effective even in small concentrations, making them a popular choice in various applications.
