Description

The AIM Physiological Monitor provides

pulse oximetry (PPG), heart-rate

variability (HRV), oxygen saturation

(SpO2), respiration, temperature,

galvanic skin response (GSR), and

four EXG channels in a portable, self-

• in the presence of ammable anesthetics

or gases

PrecautionsForThePractitioner

• Do not drop, sit on, or step on the

product.

• Check if your subject has a sensitive

dermatological condition causing sensor

intolerance.

• To avoid cross-subject contamination,

do not use with subjects having open

wounds or infections.

• The AIM is not a diagnostic tool.

Any medical diagnosis related to the

measurements should be derived by a

certied physician.

SubjectConsiderations

• This device is intended for human use

only.

• Subject should have healthy skin.

• Do not use with infants or neonates.

FollowTheseAdvisoriesToKeepYour

AIMInGoodWorkingOrder

• Do not immerse any part of the system in

liquid.

• Do not expose the system to direct

sunlight or heat source, moisture,

vibration, mechanical shock, excessive

dust, or humidity.

• Do not open, modify or disassemble any

part of the system — this will void the

warranty.

• Do not use if any part of the system is

damaged.

• Do not use when wet — if moisture

penetrates the system, let it thoroughly

dry prior to use.

• Do not use caustic or abrasive cleaners

on the system or sensors.

• Avoid sharply bending the lead wires.

DisposableSensorsMayBeA

Biohazard

Dispose of EXG sensors after each use.

AlwaysUseSuppliedAccessories

Using accessories other than those

supplied with your system may result

in damage or diminished ecacy of the

system.

AvoidCross-SubjectContamination

Clean the device and clean or replace

sensors after use following the cleaning

instructions on Page 10 to avoid cross-

subject contamination.

SensorSetupGuide

You can use any combination of sensors concurrently.

PPG/SpO2/HRSensor

To acquire PPG/SpO2/HR, connect the PPG/SpO2/HR

module to the 9-pin port on the top left side of the amplier.

You do not need to attach a ground terminal (GND).

• Clip PPG/SpO2/HR sensor onto the ngertip or earlobe.

• Go to the Display tab in the software and change the

channels from All to 1

• Set the Show Page drop-down menu to EEG7to7.

• View SpO2 and heart rate data on the Status tab in the

software.

• Heart rate is listed in beats per minute.

• SpO2 is listed as a percentage of blood oxygen

saturation.

RespirationSensorPaddles&ECGMeasurements

To acquire respiration and ECG signals:

1. Attach the two respiration paddles to the positive and

negative respiration inputs on the AIM device.

2. Attach a lead to the ground terminal (GND).

3. Snap Skintact electrodes into the respiration and

ground sensors.

4. Attach ground.

5. Apply respiration paddles to the subject so arrows

on the paddles face each other and point toward the

midline. Paddles should sit just below the collarbone.

6. To view both the ECG and respiration signals in the

software, go to the Display tab in the software and

change the channels from All to 2

7. Set the Show Page drop-down menu to EEG5to6

TemperatureSensor

To acquire temperature:

1. Connect the temperature module to the AIM. You do

not need to attach a lead to the ground terminal (GND).

2. Hold the temperature sensor in the hand or tape under

the arm for increased accuracy.

3. View temperature data (Celsius) on the Status tab in

the software.

To acquire a GSR signal:

1. Connect passive lead wires into the positive and

negative GSR ports.

2. Attach a lead to the ground terminal (GND).

3. Snap Skintact electrodes into the GSR and ground

sensors.

4. Attach ground and GSR sensors to the body.

5. To display the GSR channel, go to the Display tab in

the software and change the channels from All to 1.

EXGSensors

1. Attach passive lead wires to the positive and the

negative ExG channel inputs for however many ExG

channels you want to acquire.

2. Attach a lead to the ground terminal (GND).

3. Snap Skintact electrodes into each sensor.

4. Place the leads and ground onto the subject on the

desired locations.

5. To selectively display ExG channels, go to the Display

tab in the software and change the channels from All

to 1.

6. Navigate between the ExG channels by using the Show

Page drop-down menu.

USBDongle

Plug the dongle into your computer and Windows should

automatically install the correct drivers. Verify driver

installation by checking the Device Manager for problems,

marked by a yellow exclamation mark.

• The dongle is specic to each headset.

• For best performance, ensure a clear line of sight between

the dongle and the front of the headset

If Windows did not successfully install the driver for

the dongle, refer to the FTDI driver installation manual

on our website.

Each AIM is permanently paired to a receiver dongle. The

pair automatically discover and initiate a connection when

both are powered on and within a 10m range.

You should see CGXAIMPhys.Mon. under Discovered

Devices. If you do not, remove and re-insert the dongle,

then restart the software.

Click the device name in this window to select the AIMand

click Connect.

You should see a small pop-up window asking if you wish

to auto-congure. Click Yes. If you do not see the pop-up,
