LifeChoice Activox Oxygen FAQ’s
Choose LifeChoice Activox 4L if you need supplemental oxygen in a lightweight and portable oxygen concentrator that requires no oxygen tanks.
The LifeChoice Activox 4L portable oxygen concentrator is intended to be used by patients who are prescribed and diagnosed as requiring supplemental oxygen. It provides supplemental, high concentration oxygen to patients in the home, institution or travel environments. Please note, it is not life supporting nor life sustaining.
“Auto Mode” monitors changes in a patient’s activity level and adapts itself to their breathing requirements. In “Active-High Mode,” oxygen is tailored for short and frequent breaths required during activity. In “Rest Mode,” a more sensitive breath detection is used to identify and provide for shallow, prolonged breathing that occurs during rest.
Unlike typical pulse dose delivery, which can provide oxygen at a faster rate than the patient can inhale, Pulse-Wave helps match the oxygen delivery to a patient’s inhalation rate for comfort and synchrony. It also minimizes retrograde airflow to reduce side effects.
The internal battery runtime will vary depending on the device’s setting, the patient’s breath rate and any additional modes used. As a guide, please refer to the below table:
Device settings and estimated runtimes
Setting 1 : 10.25 hours Setting 2 : 8.25 hours Setting 3 : 5 hours Setting 4 : 4 hours
