AIM Physiological Monitor

This manual contains general operating instructions, precautionary measures,

maintenance instructions, and information for use of the CGX AIM Physiological

Monitor. Please read this manual carefully and familiarize yourself with the

controls and accessories before using the product.

Note

This is an investigational device designed for research and development efforts.

•

It is not an FDA-approved medical device.

•

There are no known side effects from the use of this product.

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-

contained, wireless system.

Wireless technology allows the subject

to move about while real-time data is

collected and displayed.

The device uses a modular design; any

combination of sensors can be used at

any time, from a single sensor to every

sensor simultaneously.

Sensor channels are sampled at a time

resolution of 500Hz and converted to

digital data at 24 bits of resolution.

The AIM Physiological Monitor provides

research-grade signal quality and is

ideally suited for laboratory and field

environments.

Page 10: Cleaning Sensors
To protect the environment, always follow local law, rules, and policies regarding electronic and battery disposal. You may also return the system to CGX for proper disposal. Use the supplied carrying case when transporting the system to avoid damage to the amplifier or any of the components.
Page 11: Troubleshooting
Since the AIM’s settings are stored in the device, this reset process can cause issues if you have changed the auto- configuration screen to fit your experiment. Please contact CGX support if you have changed your settings and need to reset your device.
Page 12 Understanding Readings Troubleshooting Readings The most important aspect of AIM recording is that output data is only as good as the recording input. While algorithms exist to remove artifacts, poorly recorded data cannot be fixed in post processing. Recording good data requires preparation of the participant for optimal sensor contact: 1.
Page 13 Understanding Readings Understanding Readings GSR Missing Ground Using the GSR leads without ground will display a sinusoidal artifact and the module will not show functional data. GSR Missing A Lead Using the GSR with only a single lead will cause a flat line. Page 13...
Page 14 Understanding Readings Respiration Paddles Placed Properly When the respiration paddles are placed properly the ECG channel will display a distinct and clean signal and the respiration paddle will be responsive to actual respiration. Respiration Paddles Too Close Together Respiration paddles placed too close to each other display poor signal quality. Amplitude of respiration and ECG channels will be lower than expected.
