How SmartDose Works

SmartDose® extends the use time from a supply of oxygen by only delivering oxygen during the portions of the breath that put the gas into the lungs. SmartDose delivers a volume of oxygen on each breath, right at the start of inhalation. It delivers the full dose (bolus) of oxygen within 2/3 of the inhale cycle. By doing so, it is not delivering oxygen at the end of inhalation or during exhalation, as other devices do.
The normal volume of oxygen that SmartDose delivers is 16 ml per setting, so that a setting of 2 delivers 32 ml of oxygen on each breath, in the first 2/3 of the inhale cycle.
SmartDose monitors a patient’s breathing patterns and automatically turns up the oxygen volume by one setting during exertion, and if breath rate continues to rise, by another setting. Many patients turn their settings up and down throughout the day, but this self administered approach is inconsistent and by the time most patients feel the need to turn it up, their oxygen levels have already dropped. SmartDose responds more quickly and consistently. SmartDose recognizes when exertion stops and lowers the volume back down to normal levels thus saving oxygen. Again, this is often an improvement over manual adjustments since patients often forget to turn the volume down after exerting. Most patients are able to be titrated at lower base settings due to SmartDose’s efficient delivery and auto-adjusting features.This extends the use time of your oxygen supply.
SmartDose also uses a multi-valve system that has multiple delivery flow rates. The unit can deliver a volume at two flow choices. The unit constantly monitors the patient’s breath rate and determines the lowest flow option to “fit” the oxygen into the first 2/3 of the inhalation cycle. By delivering at lower flows, the unit is more comfortable, and quieter than units that deliver at higher flows all the time.

SmartDose Mini Auto-Adjusting Oxygen Conserver Delivery Modes

The SmartDose Mini Auto-Adjusting Oxygen Conserver has two modes: SmartDose and Continuous Flow.
To receive the benefits of SmartDose technology, set your SmartDose Mini Auto- Adjusting Oxygen Conserver to SmartDose mode. Continuous flow mode is offered as a backup option in case your batteries run out of power. Continuous Flow mode provides a steady flow of oxygen until you can replace the batteries; it does not offer the benefits of SmartDose technology. Also, be aware that your oxygen supply will be depleted rapidly when set to operate in Continuous Flow mode.

With the Portable in SmartDose mode, SmartDose technology detects changes in your breath rate and automatically adjusts the oxygen dose using a unique valving system. In this way, the Conserver automatically adapts the oxygen flow to meet your needs as your activity level goes up and down throughout the day. After you have set the flow rate to your prescribed dose, there is no need to manually change the oxygen flow rate during the day— SmartDose technology does it for you.

SmartDose Technology helps you in two ways:

When you are active, a higher oxygen dose helps reduce feelings of breathlessness and stay active. When you are at rest and your breathing rate slows down, SmartDose technology adjusts the oxygen dose to the lower level that meets your needs. Keeping the oxygen flow rate as low as possible helps to extend oxygen duration, minimize nasal dryness and provide quieter therapy.

Changing the Batteries

When the red battery indicator light begins blinking red, it means the Conserver’s batteries are low and it’s time to replace them.
Continuous Flow mode does not require batteries and will deliver a continuous flow of oxygen, but this mode also significantly shortens the oxygen duration of your cylinder.

Follow These Steps to Replace the Batteries:

1. Remove the battery cover by pressing the clip on the top of the unit and pull the cover out.
2. Remove old batteries from the compartment and discard properly.
3. Insert 2 “AA” Alkaline with the polarity as indicated on the holder.
4. Insert the battery cover back onto the unit and push until the retaining clip snaps into place.

CAUTION Do not mix battery types.
WARNING Using the SmartDose Mini Auto-Adjusting Oxygen Conserver in ContinuousFlow mode (CF Switch pulled out) will use oxygen at a faster rate than using it in SmartDose mode. Monitor the contents of your cylinder so you do not run out of oxygen.
NOTE When using the SmartDose Mini Auto-Adjusting Oxygen Conserver in Continuous Flow mode, the indicator light will NOT light up green or red with each breath. Turning the On/Adjust button all the way down will not completely stop the flow of oxygen. To stop the flow of oxygen push the CF switch in & turn the cylinder valve off.

Attaching the SmartDose Mini Auto-Adjusting Oxygen Conserver to a

Cylinder

1. Make sure that sealing gasket is clean & no damage or tearing is present. If the gasket is damaged in any way, do not use & call your home medical equipment provider immediately.

2. Loosen the knob on the Conserver & check cylinder valve port for damage & debris.

3. Carefully lower the Conserver over the valve post of the cylinder.
   CAUTION Alignment pins can damage sealing surfaces of the valve post increasing the chance of oxygen leaking.

4. Align the pins in the Conserver to the holes in the cylinder valve post as you would a standard regulator.

5. Hand tighten the knob until the conserver is secure.
   

Starting Oxygen Delivery from the SmartDose Mini Auto-Adjusting Oxygen

Conserver

To receive oxygen from your Conserver, follow these steps.

1. Push the cannula breathing tube firmly onto the oxygen outlet port.
   

2. Open the cylinder valve by turning counter-clockwise.
   WARNING To prevent injury from cylinders tipping over, do not use cannula tubing lengths over 7 feet with small compressed oxygen cylinders. Unattended cylinders should be secured in a cylinder stand.
   A mask should not be used with the conserving device when in SmartDose mode as it may not allow triggering of the unit.
   Pediatric or low-flow cannula tubing should not be used in SmartDose mode due to increased back pressure. SmartDose delivers a volume of oxygen at the start of inhalation, but does not deliver oxygen throughout the entire inhale. Both the volume of oxygen, as well as the flow rate can vary from breath to breath.

3. Attach your nasal cannula to the cannula fitting on the Conserver.
   Up to 7 feet of cannula tubing can be used.

4. Turn on the SmartDose Mini Auto-Adjusting Oxygen Conserver by pressing and holding the On/Adjust button until all of the numerical LEDs (1 through 5) light up. SmartDose Mini Auto-Adjusting Oxygen Conserver is ready by pulsing three times.

5. Set the Indicator light to your prescribed setting (1 to 5). Be sure that the CF (Continuous Flow/SmartDose) switch is pushed in as shown, confirming that your SmartDose Mini Auto-Adjusting Oxygen Conserver is in SmartDose mode. (See figures on page 10.)

6. Place the cannula near the nose after turning on the SmartDose Mini Auto-Adjusting Oxygen Conserver.

7. Gaseous oxygen is now ready to flow from your SmartDose Mini Auto-Adjusting Oxygen Conserver, and with each breath you should receive your set dose of oxygen. Adjust the cannula breathing tube to the proper position on your nose so that you will be able to breathe the oxygen comfortably.

8. Low Battery
   • When the battery indicator lights up red with each breath, it is time to replace the batteries.
   • 2 AA batteries should last approximately 1000 hours
   NOTE If the batteries are dead and you cannot replace them, switch to Continuous Flow mode by pulling the CF switch out. Continuous Flow mode does not require batteries.
   See the “Changing the Batteries” section in this manual for more information.

9. To stop oxygen flow, push the CF switch in and the power will turn off after 5 minutes of inactivity.
   NOTE If the SmartDose Mini Auto-Adjusting Oxygen Conserver is in Continuous Flow mode, 2 LPM of oxygen will still be delivered. The conserver must be powered off & the CF switch pushed in to completely turn off the flow of oxygen.

Powering Down the Unit

When you are finished using the SmartDose Mini Auto-Adjusting Oxygen Conserver simply remove the cannula tubing. After 5 minutes of inactivity, the unit will power itself down. The unit quickly opens and closes the valves 3 times thirty seconds before powering down to alert you that it is about to shut down. In the event that you have simply been mouth breathing, this should alert you that the unit has not seen a breath and will be shutting down. Close cylinder valve when not in use.

Typical Questions and Answers

Q. How does the SmartDose work? How does it know when I’m inhaling?

A. When you inhale, you are sucking in air. This creates a very slight vacuum in the cannula tubing. A sensor in the unit is attached to the cannula tubing and can sense these very slight vacuum signals. When the Conserver sees the vacuum, it triggers the valve(s) to open. The microprocessor in the unit has calculated the volume of oxygen and knows your current breath rate. The unit calculates the flow needed to fit the volume into the first 2/3 of the breath and opens the appropriate valve for a specific time to give the correct volume of oxygen.

Q. I can’t hear / feel the pulse. How do I know that SmartDose is working?

A. Because SmartDose uses multiple valves and flows at lower rates than other conserving devices, the oxygen delivery is very gentle and sometimes is difficult to feel or hear. Look at the green indicator lights on the front of the unit. The light for your current setting will illuminate each time oxygen is delivered. Check to make sure that there is oxygen in your cylinder by looking at the contents gauge on the unit & that the cylinder valve is open. If you are still not sure, turn the dose up to feel stronger puffs of air. Then set the dose back to the desired setting.

Q. Why can’t I use a cannula longer than 7 feet?

A. The Conserver will likely still sense the vacuum and trigger with longer tubing, but the time it takes for the oxygen to travel at longer lengths of tubing will cause the oxygen to be delivered to the user later and later in the inhale cycle. Longer tubing lengths will put the delivery beyond the first 2/3 of the inhale.

Q. Can I use a humidifier with SmartDose?

A. No. The Conserver can not sense the inhale through the water of a humidifier and will not trigger. Because of the intermittent delivery of oxygen and the lower flow rates, many patients find that humidification is not necessary.
