TECHNICAL DESCRIPTION
HOW THE DEVICE FUNCTIONS
The device includes a low-pressure regulator. It is designed
for use with a cylinder as an ambulatory oxygen system. This
system takes high pressure Oxygen and reduces the pressure
to a usable pressure. It provides continuous flow through a
fixed orifice and is determined by the numerical settings on
the flow selector (example: a setting of 2 is equal to 2 liters
per minute of oxygen flow). This oxygen is then delivered to
the patient through a nasal cannula.
NOTE: The components in the medical gas path and the
nasal cannula are considered applied parts.
