The OxyGo NEXT will sense the onset
of inhalation and deliver a burst of
oxygen at a precise time when you
inhale. The OxyGo NEXT will sense each
breath and continue to deliver oxygen
in this manner. As your breathing rate
changes, the OxyGo NEXT will sense
these changes and deliver oxygen only
as you need it. At times, if you inhale
very quickly between breaths the OxyGo
NEXT may ignore one of the breaths,
giving the appearance of a missed
breath. This may be normal as the
OxyGo NEXT senses and monitors the
changes in your breathing pattern.
