GENERAL INFORMATION

Introduction

Refer to the instruction guide (A-306-1 or A-306-2) for set up and
operating instructions. This service manual is designed to provide
DeVilbiss Healthcare qualified service technicians and homecare
providers with the proper maintenance and safety procedures for
the DeVilbiss iGo Portable Oxygen System. Please read and
understand all the information contained in the instruction guide
and this service manual before attempting to operate or perform
any maintenance.
DeVilbiss reserves the right to alter or change the design of the
DeVilbiss Portable Oxygen System. Hence, slight differences in
construction or components may exist between the unit in hand and
that which is described in this manual.

Functional Description

The 306 series is a portable medical oxygen concentrator designed
to deliver either a continuous flow (CF) of oxygen—up to 3 liters
per minute (LPM), or a bolus of oxygen upon inhalation
(PulseDose mode)—equivalent to 1-6 LPM CF, through an oxygen
®
outlet. The unit contains an able/disable feature for locking and
unlocking the flow settings in both modes.
In PulseDose mode, a pressure switch detects inhalation as a
reduction in cannula pressure and opens a demand flow valve that
delivers the prescribed bolus of oxygen before the patient begins
exhalation. The iGo accommodates breath rates up to 40 breaths
per minute (BPM) at settings 1-4, 37 BPM at setting 5, and 31 BPM
at setting 6, and requires the use of a nasal cannula: mouth
breathing is not compatible with PulseDose operation.
NOTE–If the pressure switch does not detect a breath within 30
seconds while the unit is operating in PulseDose mode, the iGo
sounds an audible alert every 3 seconds for one minute with a
blinking yellow light. If breathing is not detected after one minute,
the unit switches to Continuous Flow mode and the CF light
illuminates clearing the No Breath Detected alert.

1. Power button – turns the system ON or OFF
2. No Breath Detected light (PulseDose mode ONLY) –
illuminates intermittently and an audible alert sounds every 3
seconds, if the iGo is operating in PulseDose mode and does
not detect a breath for 30 seconds. If a breath is detected
during the alert, the alert condition is cleared. If a breath is not
detected during the alert, the unit changes to continuous flow
mode after 60 seconds of alerting.
NOTE–Once the unit changes to continuous flow, use the
Mode Select button to change back to PulseDose.
3. External Power light – illuminates when the iGo system is
connected to either AC or external DC power.
Power Fail alert – illuminates intermittently with an audible
alert for 15 minutes. Pressing the Power button stops the alert.
4a. Green Normal Oxygen light – illuminates when the iGo
delivers 84% or greater oxygen purity.
4b. Yellow Low Oxygen light – illuminates if the iGo delivers 76%
to 83% oxygen purity.
4c. Red Service Required light – illuminates with an audible alert if
the iGo delivers 75% or less oxygen purity or if component
failure is detected.
5a. Mode Select button – selects the mode of oxygen delivery
(PulseDose or Continuous Flow).
5b. Flow Indicator light – in PulseDose mode, pulses ON with
every breath; in Continuous Flow mode, illuminates
continuously
6a. Flow Rate Indicator lights – illuminate the flow rate at which
the iGo is set to deliver oxygen.
6b. Flow Rate Control buttons – increase or decrease the flow
rates in PulseDose (1 to 6 LPM) or Continuous Flow (1 to 3
LPM) as ordered by the physician.
7. Battery Charge lights – indicate the battery pack's charge
status.
• When the battery is fully charged, all six lights illuminate.
As the battery discharges, the lights turn off one by one.
Each illuminated light indicates approximately 45 minutes
of battery charge at 2 LPM in PulseDose mode.
• When the battery is charging, the lights illuminate in a
cycle pattern.
• When the battery has approximately 10% of capacity, a
yellow battery light illuminates with a single audible alert.
• When the battery is depleted, the unit enters Power Fail
alert.
