| 1. | To use, open the cylinder valve (the black hand wheel at the top of the oxygen cylinder) by turning it counter-clockwise. Check the pressure reading of the oxygen meter to see if there is sufficient pressure inside the cylinder. When a cylinder is full the pressure should read 120 kg/c㎡. The pressure reading will gradually decrease with use. |
| 2. | Connect one end of the nasal cannula to the vent of the flow meter and it is ready for use (keep the distilled water inside the humidifier bottle below the fill line).
|
| 3. | Turn the flow adjustment knob (the green knob in front of the oxygen flow meter) to adjust the oxygen flow rate per minute. Turn counter-clockwise to open, and clockwise to close. The unit of measurement LPM (Liter per Minute) on the oxygen flow meter indicates the number of liters per minute. A flow rate of 1 ~ 3 LPM is generally recommended or as prescribed by the doctor.
|
| 4. | After use, close the hand wheel by turning it clockwise. Once the residual pressure in the canula has been vented the pressure reading will revert to zero. Now turn the flow rate adjustment knob in the clockwise direction and close it tightly.
|
| 5. | The duration of this oxygen cylinder's oxygen supply will depend on its LMP setting. |
