100 DeVilbiss Drive Somerset, PA 15501 800.338.1988 www.DeVilbissHealthcare.com 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: Setting 1.0 2.0 3.0 4.0 5.0 6.0 Continuous Flow 4.0 hours 2.4 hours 1.6 hours ---- PulseDose (20 BPM) 5.4 hours 4.7 hours 4.0 hours 3.5 hours 3.2 hours 3.0 hours 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 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. 100 DeVilbiss Drive Somerset, PA 15501 800.338.1988 www.DeVilbissHealthcare.com Q10: Can I use a humidifier bottle with iGo? A10: Yes and no. You can only use a humidifier bottle with iGo while in the continuous flow mode. A humidifier bottle cannot be used while the iGo is set to pulse mode. Q11: Can I use the iGo 24 hours per day? A11: Yes. iGo may be used for continuous oxygen therapy. Q12: Can I use the iGo without a battery pack? A12: Yes. iGo can be operated from an external power source if the battery pack is not installed. Q13: What maintenance is required for the iGo? A13: The dust filter located inside the handle recess should be cleaned regularly. There is no other routine maintenance during the first 3 years of operation. Q14: Can I leave iGo plugged in continuously even though the battery is fully charged? A14: Yes. The iGo stops charging the battery once it is full. There is no danger in leaving the iGo plugged in. Q15: How do I know how much power remains in the battery? A15: Install the battery into the iGo, and turn the unit on without external power connected. The battery status indicator will display the amount of power remaining. Q16: What happens if the power fails while I’m using the iGo? A16: If you are operating the iGo from an external power sources and the external power fails, the iGo will automatically switch to the internal battery pack (if the battery is installed). If the external power resumes before the battery is fully discharged, iGo will automatically switch back to external power. If the external power does not resume, the iGo will provide battery status indications, and the iGo will sound an audible beep. The external power light on the control panel will blink once the battery is fully depleted. If there I no internal battery pack installed, the iGo will sound an audible beep, and the external power light on the control panel will blink immediately. Q17: How do I know if the iGo is set to continuous flow? A17: The green light beside the mode select button will be lit continuously. Q18: How do I know if the iGo is set to pulse mode? A18: The green light beside the mode select button will blink each time a breath is sensed. Q19: How can I tell if the oxygen purity is good? A19: As long as the green O2 light is illuminated, the iGo is delivering the proper purity of oxygen. If the purity drops below the proper level, the yellow O2 light will be illuminated. You may continue to use the iGo even though the yellow light is on, but you should quickly find an alternative oxygen source. If the purity continues to drop, the red service light will illuminate. You should immediately find an alternative oxygen source. Q20: How long of an oxygen tube can I use with iGo? A20: You may use a tubing length of up to 35 feet (10 meters) when in pulse mode and up to 50 feet (15 meters) while in continuous flow mode.
