FLOW RATE VS OXYGEN CONCENTRATION
The concentration of oxygen delivered is controlled by the flow rate which can be adjusted by the knob on the flow meter, which is
located on the right hand side of the machine. The higher the flow rate, the lower the oxygen concentration. Please refer to the chart
below for details. Turn the knob anti-clockwise to increase the flow rate and decrease the oxygen concentration. The flow rate is
indicated by a black bead inside the glass tube of the flow meter. Please use the concentration and flow rate as prescribed by your
physician.
