Theory of Operation
Introduction
The Companion 5 is a stationary medical device used to extract
oxygen from the atmosphere, concentrate it, and present the
oxygen to the patient. The device will operate in Continuous Flow
Mode. In Continuous Flow Mode the oxygen is provided at a con-
stant flow rate between 0.5 and 5.0 LPM (Continuously Variable).
Table 2 below lists the major internal components of the con-
centrator and their functions. Reference Table 2 and Figure 3 (on
the following page) for clarification while reading the Theory of
Operation Section of the manual.
Item Function

Printed
Circuit Board
(PCB)
Responsible for all of the electrical operation of the
concentrator. Contains a programmable micropro-
cessor that controls valve timing, alarm indications,
and OCSI functions (if applicable).
Table 2: Internal Components of Concentrator
Pressure Swing Adsorption
The CAIRE Companion 5 utilizes the Pressure Swing Adsorption
(PSA) Process to concentrate oxygen gas from ambient air. In the
PSA process, a compressor draws ambient air into the machine
through an intake filter. The compressor then forces the filtered air
into a solenoid valve which directs the air into one of two tanks
that are full of a molecular sieve material, referred to as sieve
beds. As the pressure in sieve bed 1 increases, nitrogen molecules
are removed from the ambient air and are stored in the sieve
material. The gas that exits sieve bed 1 is highly-concentrated
oxygen. The majority of this gas flows through an orifice to sieve
bed 2 and is used to purge the stored nitrogen gas from its sieve
material. The remainder of the oxygen gas is directed through a
apper valve to the product holding tank. Here, it is stored for
delivery to the patient.
Sieve bed 1 continues to pressurize until the sieve material is
completely saturated with nitrogen. At this time the printed circuit
board (PCB) switches the state of the solenoid valve, dumping
pressurized air in sieve bed 1 back into the atmosphere via the
purge mufer. Simultaneously, the valve now directs the com-
pressed air into sieve bed 2, which has been completely purged of
nitrogen gas and is ready for nitrogen adsorption/oxygen concen-
tration. This cycle continuously repeats pressurizing and depressur-
izing the sieve beds, feeding concentrated oxygen to the product
holding tank.

Oxygen Concentrator
PN 14940837 B — 12
Flow Delivery
Oxygen exiting the product holding tank flows through a pressure
regulator that reduces the high pressure oxygen to a lower, more
manageable pressure before it is delivered to the patient. This
ensures that the oxygen flowing from the device will work ap-
propriately with accessories and provide a safe pressure for patient
delivery.
The Companion 5 oxygen concentrator may be equipped with
an Oxygen Concentration Status Indicator (OCSI). In that case,
oxygen gas exiting the pressure regulator flows through a check
valve and then through the OCSI sensor. This is the same area of
the concentrator where the flow is measured. The PCB monitors
the concentration and the ow measured by these sensors, and
it will activate a warning light and audible alarm if the concentra-
tion drops below predetermined levels described in the Warning
Alarms section of the manual.
After exiting the concentration and ow rate sensors, oxygen
flows through the flow control valve (FCV) at the LPM flow rate
selected by the patient and indicated on the flow meter. The
oxygen gas then flows through the HEPA filter where unwanted
contaminants are removed. The oxygen is then delivered to the
patient through the outlet barb.
Figure 3: Schematic Diagram of Pneumatic Operation
Electrical Operation
All electrical components of the CAIRE Companion 5 are all
controlled by a PCB. The electrical cord supplies mains AC power
(120 VAC @ 60 Hz or 230 VAC @ 50 Hz) to the main circuit board
when the power switch is in the “ON” (|)position. The PCB dis-
tributes the mains power to all of the electrical components. The
AC mains power is distributed and routed directly to the compres-
sor and the cooling fan. The compressor and cooling fan both
operate at 120 VAC @ 60 Hz or 230 VAC @ 50 Hz. The remaining
power travels to a DC power convertor/regulator. Figure 4 is a
block diagram showing the flow and distribution of mains power
into the concentrator.

Microprocessor
The microprocessor is the only processing element of the CAIRE
Companion 5. It contains embedded software which is pro-
grammed with all of the parameters for alarm conditions and
settings of the concentrator. The microprocessor is directly respon-
sible for the following functions of the concentrator:
• Cycling (timing) of the 4-way solenoid valve
• Driving the LCD display
• Controlling the audible alarm
• Controlling the operational and warning LED lights
• Reading input from the OCSI sensor (OCSI models only)
The microprocessor is programmed with the alarm thresholds and
trigger points, as well as the timing of the 4-way solenoid valve
to cycle between sieve beds. A diagram of the input and output
of the microprocessor is shown below in Figure 5. Each input and
output is described further in the following sections.
Figure 5: Microprocessor Operation Block Diagram
4-Way Solenoid Valve
The solenoid valve is connected to the circuit board’s microproces-
sor by a 4-pin connector. The microprocessor is responsible for
sending the signal to open and close the valves. This cycles the air
through alternating sieve beds for the PSA process. The timing for
alternating the sieve beds is programmed into the microprocessor.
LCD Display
The 6-digit digital LCD display is mounted on the PCB and is vis-
ible on the front of the concentrator. Its purpose is to continually
count and display the hours that the concentrator has been in
operation and to display alarm conditions. The LCD display cannot
be re-set and displays time to the nearest tenth of an hour.
Audible Alarm
The CAIRE Companion 5 contains an audible buzzer that is sur-
face mounted on the PCB. Its purpose is to alert users of alarm
conditions. The microprocessor detects alarms by reading the
input from the OCSI sensor and the mains power switch. When
there is an alarm condition, the microprocessor sends a signal to
activate the audible alarm.
LED Lights
There are two (2) or three (3) (OCSI) LED lights that are surface
mounted on the PCB. They are visible from the front of the
concentrator and their purpose is to alert the user of operating
conditions or alarms.
The top LED indicator is green. It remains on at all times when the
power switch is in the “ON” (|) position and the electrical cord is
plugged in. A continuous green light indicates normal operation.
The next LED indicator will be red. This light will indicate mal-
functions with the device. When the microprocessor detects an
alarm condition from the power switch or the ow rate sensor, it
will send a signal for the red LED to illuminate. The red LED will
indicate a system malfunction, loss of power, or ow rate is out of
specifications.
The bottom LED indicator will be yellow (OCSI Models only). This
light will only indicate low oxygen concentration. This LED will
illuminate when the microprocessor detects an alarm condition
from the OCSI sensor. The LED will be solid if the oxygen concen-
tration is 70%-85%, and it will ash if the concentration is less
than 70%. The warning alarms section will describe these alarm
conditions in detail, and provide basic troubleshooting steps.

Oxygen Concentrator
PN 14940837 B — 14
OCSI Sensor – (OCSI units only)
The OCSI sensor detects the oxygen concentration of the air
being delivered to the patient. The sensor consists of an intake
and outlet port on each end of a flow path that is encased in an
air-tight cover. The microprocessor determines concentration from
the OCSI sensor output, and activates alarms when appropriate.
The limits for alarm conditions are programmed into the software
of the microprocessor and are described in the Warning Alarms
section of this manual. The concentrator takes several minutes to
build internal pressure and concentration. This is known as the
warm-up period, and the signal from the sensor is ignored by the
PCB for ten (10) minutes. This means that the alarms associated
with the OCSI will not activate until this predetermined amount of
time has passed.
Serial Number Identification
The serial number of the CAIRE Companion 5 is located on the
back label of the outer case. The serial number is in the middle of
the label, just below the bar code. A sample label is shown below.

disconnecting the AC Power cord.
Using Around the House
Your patient may use 50’ tubing when operating the Companion
5 in the house. When a humidier is used, the tubing between it
and the patient must not exceed 7’.
CAUTION When using a humidier adapter of any kind,
the Companion 5 unit must remain stationary,
meaning that the unit must NOT be moved or
transported in any manner to avoid damage to the
Companion 5.
Locating the Companion 5 for Proper
Use and Ventilation
Ask your patient where they would like to set up the device.
Whenever possible, the Companion 5 should be in the same room
as the patient for convenience and assurance that the patient can
adequately hear and respond to Companion 5 alerts and alarms.
While unpacking and setting up the device, tell your patient about
these important cautions and warnings:
WArnIng: LoCAte the ComPAnIon 5 In A WeLL-ventILAted
sPACe thAt ProvIdes AdequAte AIrfLoW.

When the Companion 5 is plugged in properly and turned on,
a green indicator on the LED Display will light up. After initially
powering ON the device, please allow up to ten (10) minutes for
the device to reach its performance specifications.
Note: All LED lights will illuminate upon start-up. After the concentrator com-
pletes the warm-up cycle, only the green light will remain on.
For OCSI Models: The O2 Light will illuminate for four (4) seconds
upon start-up. After this initial start-up, this light is disabled for
approximately ten (10) minutes while the concentration rises to
specifications.
The warm-up period could be up to 10 minutes. After this time,
only the green LED remains lit to indicate normal operation.
