Who the Drive DeVilbiss iGO2 Is For?
The Drive DeVilbiss iGO2 is a pulse dose portable oxygen concentrator weighing 4.95 lbs with settings 1 through 5 and a SmartDose mode. Its defining feature is patented SmartDose Technology, which adjusts oxygen delivery based on the patient's breathing pattern rather than delivering a fixed bolus on every breath.
The iGO2 is a good fit for patients whose prescription falls within settings 1 through 5 and who want an intelligent delivery system from an established medical device manufacturer. At 37.5 dB at setting 2 it is quiet, and at 4.95 lbs it is light enough for daily shoulder carry.
It does not offer continuous flow. If your prescription requires continuous flow at any setting, you need a different device. If your prescription is pulse dose only and your setting falls within 1 through 7, the Vita-Ox HD7 at 4.37 lbs starts at $1,995 — $500 less than the iGO2 — and provides significantly longer battery life. That comparison is covered below.
SmartDose Technology Explained
SmartDose is Drive DeVilbiss's patented breath-responsive oxygen delivery system. Standard pulse dose POCs deliver the same oxygen bolus on every breath regardless of how fast or slow you are breathing. SmartDose adjusts the delivery based on your breathing pattern, which optimizes oxygen delivery to match your actual respiratory demand.
When SmartDose is enabled on the iGO2, the display shows settings 1 through 5 with the "SD" logo. You can turn SmartDose on or off by pressing the SmartDose button on the control panel. At SmartDose setting 5 (5 SD), the device delivers 1,100 ml per minute total volume at 15 BPM, the highest output available on the device.

Pulse Dose Output by Setting and Breathing Rate
The table below shows exactly how much oxygen the iGO2 delivers per breath at each setting, in both standard and SmartDose modes. These figures are sourced directly from the official Drive DeVilbiss iGO2 user manual (Table 1).

Oxygen Flow Equivalents
The table below shows how the iGO2's pulse settings approximately correspond to continuous flow equivalents. This is theoretical and based on typical breathing pattern assumptions. It is not a substitution for titration and should not replace physician-prescribed settings.
| iGO2 Pulse Setting | PulseDose Bolus at 20 BPM (ml) | Equivalent CF Setting (L/m) | iGO2 Oxygen Output |
|---|---|---|---|
| 1 | 13.0 | 1.0 | 90% plus or minus 3% |
| 2 | 22.0 | 2.0 | 90% plus or minus 3% |
| 3 | 36.3 | 3.0 | 90% plus or minus 3% |
| 4 | 44.0 | 4.0 | 90% plus or minus 3% |
| 5 | 50.7 | 5.0 | 90% plus or minus 3% |

Travel with the Drive DeVilbiss iGO2
The iGO2 meets airline use requirements per RTCA DO-160G Section 21 Category M and Section 20 Category T for carriage and use onboard commercial aircraft. Always confirm policies with your specific airline before travel, as individual carriers have requirements beyond RTCA compliance.
Battery and Power Details
The iGO2 uses a lithium-ion battery that must be installed for the device to operate regardless of whether AC or DC power is connected. The battery charges automatically whenever the concentrator is connected to an appropriate power source.
Battery charge indicators
- Green bar graph: 10% to 100% remaining
- Yellow bar graph: 10% or less remaining
- Red bar graph with audible alert: 5% or less remaining
- Device shutdown: Within two minutes of reaching 5% charge
OSD oxygen monitoring
The iGO2 includes an Oxygen Sensing Device (OSD) that monitors oxygen purity after approximately 10 minutes of operation. Once stabilized, the OSD displays a green normal oxygen symbol when purity is at or above 86%, a yellow caution symbol when purity is below 86%, and triggers a yellow symbol with audible alert when purity drops below 85%.
Frequently Asked Questions
What is SmartDose Technology on the iGO2?
SmartDose is Drive DeVilbiss's patented breath-responsive pulse dose delivery system. It adjusts oxygen delivery timing and volume based on your breathing pattern, rather than delivering the same fixed bolus on every breath. SmartDose mode is activated via the SmartDose button on the control panel and is indicated on the display with the SD logo. At SmartDose setting 5, the device delivers 1,100 ml per minute total volume at 15 BPM.
How long does the iGO2 battery last?
The iGO2 operates for a minimum of 3.5 hours at setting 2 at 20 BPM using a new fully charged battery. After approximately 300 charge/discharge cycles, battery capacity may be reduced to around 75 percent of original, yielding approximately 2.5 hours at setting 2. Battery recharge time is less than 3 hours from AC or less than 4 hours from DC when fully discharged.
Does the iGO2 meet FAA acceptance criteria for air travel?
Yes. The iGO2 meets airline use requirements per RTCA DO-160G Section 21 Category M and Section 20 Category T. Always confirm policies with your specific airline before travel and carry batteries for at least 150 percent of your total expected travel time.
How does the iGO2 compare to the Vita-Ox HD7?
Both are pulse dose portables. The Vita-Ox HD7 weighs 4.37 lbs with settings 1 through 7, up to 5.5 hours battery life at setting 2, 37 dB at setting 2, and a 5-year warranty starting at $1,995. The iGO2 weighs 4.95 lbs with settings 1 through 5 plus SmartDose, minimum 3.5 hours at setting 2, 37.5 dB at setting 2, and starts at $2,495. For most patients whose prescription falls within settings 1 through 5, the Vita-Ox HD7 provides more value. The iGO2's advantage is its patented SmartDose breath-adaptive technology.
Can I use a humidifier with the iGO2?
No. The Drive DeVilbiss iGO2 is not intended for use with a humidifier. It will not function with a humidifier, and using one may impair device performance. Only manufacturer-approved accessories should be used with this device.
Does Medicare cover portable oxygen concentrators?
Medicare coverage for POCs is more limited than most people expect, and Main Clinic Supply does not bill Medicare or work with insurance directly. We are a cash-pay retailer. Many patients find that purchasing privately is faster and simpler than the Medicare rental process. For details, see our Medicare coverage guide or consult your plan administrator.
What is the oxygen output level of the iGO2?
The iGO2 delivers 90 percent oxygen plus or minus 3 percent across its entire operating range at all settings. It takes up to 10 minutes after startup to reach this level. The built-in OSD system continuously monitors purity and alerts you if it drops below 86 percent.
