NOTES:
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 (SportDose 1) during
exertion, and if breath rate continues to rise, by another setting
(SportDose 2). 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.
Refer to Appendix for oxygen duration times at various settings.

SmartDose Liquid Oxygen Portable Delivery Modes
Checking the Level of Liquid Oxygen
The SmartDose Liquid Oxygen Portable comes provided with a gage to
determine the amount of oxygen contained. Follow these steps for
using the contents gage.
The SmartDose Liquid Oxygen Portable has two modes:
SmartDose and Continuous Flow.
To receive the benefits of SmartDose technology, set your SmartDose
Liquid Oxygen Portable 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.
1. Remove Portable from bag or any other container you might
be using. Slide the button on the gage strap into the slot on
the Portable handle. Lift the Portable from the top D-ring
on the gage to suspend it.
2. Let the portable stabilize (do not bounce or shake it) for about
5 seconds. Observe the location of the slider marker in the gage
window.
SmartDose mode
Continuous Flow mode
CF switch pulled out
CF switch pushed in
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 SmartDose Liquid Oxygen
Portable 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
Filling a SmartDose Liquid Oxygen Portable
When the red battery indicator light begins blinking red, it means the
SmartDose Liquid Oxygen Portable’s batteries are low and it’s time to
replace them. A continuous, non-blinking red light means the batteries

are dead. Until you can replace the batteries, you should switch the portable
to Continuous Flow mode by pulling the CF switch out. Leave the equivalent
liter flow setting, as indicated by the Dose Indicator Lights, at your
prescribed setting. 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 portable.
To fill your SmartDose Liquid Oxygen Portable, follow the instructions
in the manul for your oxygen source, and note all applicable warning
and cautions. All terms abbreviations and symbols, safeguards,
cautions, warnings, notes and indications for use within this manual
still apply.
Please note, the Fill Valve must be held open during the fill process
shown below:
Follow these steps to replace the batteries.
1. Open the battery compartment on
the back of the portable.
2. Remove old batteries from the
compartment by pulling the
ribbon to dislodge each battery.
3. Place the batteries in the battery
compartment matching the
designations in the battery holder. Ensure that the ribbon is
placed below the batteries to aid in future removal. Confirm that
all batteries are oriented properly, with the negative (-) pole
touching the springs in the battery compartment.
4. Close the battery compartment lid. Turn the unit back on by holding
the Activation Button. Verify that the batteries are installed correctly
by pushing the CF switch in and adjusting the setting by pressing
the Activation Button to cycle through the Dose Indicator Lights
stopping at your prescribed setting. The battery indicator light
should start to blink red, then green, and the portable can now
be used.
Using the SmartDose Liquid Oxygen Portable in Continuous
Flow mode (CF Switch pulled out) will use oxygen at a faster
rate than using it in SmartDose mode. Monitor the contents
of your SmartDose Liquid Oxygen Portable as described in
“Checking the Level of Liquid Oxygen” so you do not run out
of oxygen.
WARNING
When using the SmartDose Liquid Oxygen Portable in
Continuous Flow mode, the indicator light will NOT light up
green or red with each breath. Turning the setting all the way
down via the Activation Button will not completely stop the flow
of oxygen. To stop the flow of oxygen push the CF switch in &
power off.
