Important Information
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.

Typical Questions and Answers
SmartDose Mini Auto-Adjusting Oxygen Conserver Overview
Q. How does the SmartDose work?
How does it know when I’m inhaling?
The illustration shows the parts of the SmartDose Mini Auto-Adjusting
Oxygen Conserver.
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.
1. Knob - used to attach the Conserver to the cylinder.
2. SmartDose Indicators - One green light illuminates one flash on each
breath when in SmartDose mode to show the current setting.
3. SmartDose On/Adjust Button - use this to power on and adjust the
patient setting.
- Push and release to turn on. Push and hold to change settings.
4. Low Battery Indicator
- Flashes red when batteries are low, & should be replaced as soon as
- Solid red means batteries are dead.
Q. Why can’t I use a cannula longer than 7 feet?
5. Cannula Fitting – Use this fitting to attach the cannula tubing.
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.
6. Oxygen Contents Gauge – Indicates the remaining pressure in the
oxygen cylinder.
When this gauge falls into the red section, you should switch to a
new cylinder.
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.
7. Continuous Flow (CF) Knob – Pull knob out to switch unit to 2 LPM
CF oxygen.
Does not require batteries. Knob must be in to initiate SmartDose.
8. Battery Compartment – Battery holder for 2 AA alkaline batteries.
Note polarity when inserting new batteries.
SmartDose Mini Auto-Adjusting Oxygen Conserver Delivery Modes
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.)
Place the cannula near the nose after turning on the
SmartDose Mini Auto-Adjusting Oxygen Conserver.
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.
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
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.
To stop oxygen flow, push the CF switch in and the power will turn off
after 5 minutes of inactivity.
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.
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.
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.
Starting Oxygen Delivery from the SmartDose Mini Auto-Adjusting
Oxygen Conserver
To receive oxygen from your Conserver, follow these steps.
Push the cannula breathing tube firmly onto the oxygen outlet port.
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:
Open the cylinder valve by turning counter-clockwise.
Remove the battery cover by pressing the clip on the top of the
unit and pull the cover out.
Remove old batteries from the compartment and discard properly.
Insert 2 “AA” Alkaline with the polarity as indicated
on the holder.
Insert the battery cover back onto the unit and push until the
retaining clip snaps into place.
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
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.
Attach your nasal cannula to the cannula fitting on the Conserver.
Up to 7 feet of cannula tubing can be used.
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.
Do not mix battery types.
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.
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
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.
Loosen the knob on the Conserver & check cylinder valve
port for damage & debris.
Carefully lower the Conserver over the valve post of the
Alignment pins can damage sealing surfaces of the valve
post increasing the chance of oxygen leaking.
Align the pins in the Conserver to the holes in the
cylinder valve post as you would a standard regulator.
Hand tighten the knob until the conserver is secure.
