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 inhalatio
n 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 an
other 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 oxy
gen.
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.
