not last as long at different altitudes due to the change in the amount of oxygen available.
Q9: What percentage of oxygen does the iGo deliver?
A9: iGo provides 91% oxygen, +/- 3%. This purity has been tested to be clinically acceptable
for long-term oxygen therapy.
Frequently Asked Questions
iGo™ Portable Oxygen System
Q1: How long will the iGo battery pack operate the unit?
A1: The actual run time of the iGo on the internal battery pack depends on several factors, including
flow rate, breath rate, altitude, temperature and the age of the battery pack. Following are run-time
estimates for the iGo with a new, fully charged battery pack:

Q2: Will the run time of the iGo battery pack change?
A2: Yes. As lithium ion batteries age, the duration of operation will decline. The iGo battery pack may
operate at as low as 80% of its usual life when it was new.
Q3: Can I use an external charger to charge the iGo battery pack?
A3: Yes, an iGo Battery Charger is available for purchase. It was designed to recharge iGo batteries
separate from the iGo unit in approximately three hours.
Q4: Can I use the iGo in a different carrying case?
A4: No. iGo can only be used inside an approved DeVilbiss carrying case. Approved carrying cases
have proper ventilation screens to provide adequate airflow for operation and cooling.
Q5: My iGo is plugged into an AC wall outlet, but the battery is not charging. Why is this?
A5: If the battery is too hot or too cold the iGo charge circuit will not charge the battery. Please allow
the battery to warm or cool to room temperature before charging.
Q6: The iGo is making noise while plugged in even though I am not using it. Why is this?
A6: The internal cooling fan on the iGo will continue to operate while charging the battery. This is done
to keep the battery at an appropriate temperature and speed up the charge time. The fan will shut
off as soon as the battery is charged.
Q7: I keep pressing and holding the up or down arrows to set the flow rate, but the flow rate
does not change. Why is this?
A7: You must press the button once for each setting. This is done to prevent accidental flow rate
changes.
Q8: Can I use the iGo at high altitudes?
A8: Yes. iGo can be used at altitudes up to 13,000 feet or 4,000 meters. The iGo battery may
