Step-by-step explanation:
Xe133, also known as Xenon-133, can be used in various settings in hospitals. It can be used in rooms that are held at a positive pressure to surrounding areas, such as operating rooms or isolation units. Additionally, Xe133 can be used in patient rooms if they are private, and in imaging rooms that have a ceiling vent. Lastly, Xe133 can also be used in rooms that are held at a negative pressure to surrounding areas, such as burn units. However, it should not be used in rooms where oxygen is in use.
