Oxygen Cylinder Duration

Because the total delivery of oxygen via the EVOLUTION conserver is related to breathing rates, it is user adaptive in that the total oxygen delivered per minute will automatically adjust with user need, as expressed by increased or decreased breathing rates. For example, in all settings, twice as much oxygen per minute will be delivered if one breathes twenty (20) times per minute as compared with ten (10) times per minute. The table below provides useful information to be used as a guide.

How to Install Drive Chad Conserver?

1. Loosen the cylinder adjustment handle.
2. Lower the EVOLUTION conserver over any CGA 870 post-valve cylinder with the alignment pins toward the holes on the cylinder neck.
3. Align the two (2) pins and seal the washer with the corresponding holes on the cylinder post valve.
4. While holding the unit in place, tighten the cylinder adjustment handle by turning it clockwise.

How to Operate this Oxygen Conserver?

1. Make sure the EVOLUTION conserver is set to the “PULSE” position. Battery-saving technology has eliminated the need for an “OFF” position. The unit will go to “Sleep Mode” after three minutes of non-use. The unit will turn on again when inspiration is detected or the Selector Button is pressed.
2. To reduce the risk of rapid oxygen recompression and fire, OPEN THE CYLINDER VALVE SLOWLY and completely so that the pressure gauge moves slowly as it indicates the cylinder pressure.
3. Listen for leaks. If a leak is present, close the cylinder valve, check the seal washer, and reinstall. If the leak persists, DO NOT USE THE EQUIPMENT. Contact your supplier for repair.
4. To select the setting on the EVOLUTION conserver (1-7) that corresponds to the appropriate delivery setting, press and hold the Selector Button in the center of the Selector Knob until the appropriate LED display light is illuminated.
   NOTE: To check your current setting, press and release the Selector Button in the center of the Selector Knob.
5. Place the nasal cannula into position with the prongs in the nostrils and begin breathing. The EVOLUTION conserver will now start to deliver oxygen. The amount of oxygen delivered is determined by the setting. Adequate oxygen delivery will be achieved because of the precise time in the breathing cycle that the pulse of oxygen is delivered.
   NOTE: To help prevent possible damage to the unit, keep the EVOLUTION conserver in a carrying bag. Several bags are available for use with different cylinder sizes and configurations.
6. When finished using the system, turn off the oxygen supply cylinder valve and continue breathing through the nasal cannula until no further oxygen is detected.
7. Remove the nasal cannula.
8. When not in use, store in a clean, dry location
