SmartDose Mini+ Gas Conserver Overview
The illustration shows the parts of the SmartDose Mini+ Gas Conserver.
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
possible.
- Solid red means batteries are dead.
5. Cannula Fitting – Use this fitting to attach the cannula tubing.
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.
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.
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 ha
s
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 conservin
g 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.
