Power of Auto Mode & PULSE-WAVEŹ™ Delivery

LifeChoice Activox POCs feature unique Auto Mode and PULSE-WAVE™ Technology which work together to deliver gentle and effective oxygen therapy.

To learn how Auto Mode and PULSE-WAVE™ work, watch the animation below.

PULSE-WAVE™ refers to the type of delivery LifeChoice Activox POCs utilize. This technology delivers oxygen in a manner that is congruent with your breath rate so that all of the oxygen dose is received. This gentle form of delivery helps minimize uncomfortable side effects associated with other types of oxygen therapy such as dry nose and nose bleeds.

Power That's Affordable

LifeChoice Activox POCs are reimbursed by Medicare and most private insurance plans. The Standard Package includes all the necessary elements for easy use and portability. To learn more about what is included, click the Standard Package tab above.
