The Variable flow devices deliver an uncontrolled amount of oxygen, in other words, they are the system allows for mixing of the oxygen with air drawn into the system opposite to fixed flow devices. They are used in cases where the patient does not need a controlled through holes in the adaptor. amount of oxygen. Hudson delivery device This is the mask shown in the first image above.
