 Innovative Auto Mode

The LifeChoice

®

 Activox

 4L features 

powerful Auto Mode and PULSE-WAVE

® 

technologies which work together to keep you 
saturated around the clock. 

Auto Mode detects changes to your breath 
rate and automatically adjusts the delivery 
of oxygen, while PULSE-WAVE

®

 Technology 

delivers that oxygen to you in a manner that 

is congruent with your breath rate so that all 

of the oxygen dose is received. This 

type of delivery is gentle and helps 

minimize uncomfortable side effects 

associated with other forms of 

oxygen delivery such as dry nose 

and nose bleeds.
