Frequently asked questions
What are the main applications of the Grass Comet Portable EEG/PSG System?
The Grass Comet Portable EEG/PSG System is primarily used for:
- Electroencephalography (EEG): Monitoring brain activity.
- Polysomnography (PSG): Sleep studies and monitoring.
Is the Grass Comet system channel capacity expandable?
Yes, the Grass Comet Portable EEG/PSG System is designed with expandability in mind to support comprehensive data acquisition for both PSG and EEG studies. This versatility is one of its key selling points.
- Base Capacity: The core AS40 amplifier system provides 40 AC channels.
- Maximum Expansion: The system is architecturally designed to be easily upgradable, allowing for a total capacity of up to 50 channels.
- Expansion Flexibility: Monitoring capabilities can be further enhanced with an optional 8-channel DC input module for capturing a wider range of physiological parameters. It also supports integrated pulse oximetry for SpO2 and heart rate data.
What essential components are included?
The “Previous Model - PSG” configuration of the Certified Refurbished Grass Comet Portable EEG/PSG System includes the following essential components:
- Grass Comet AS40 Amplifier: This is the high-response central unit for monitoring.
- SPM PSG Personality Module: Comes with a built-on cable, specific for Polysomnography (PSG) studies.
- Nonin XPOD SpO2 Adapter: Integrates for SpO2 and heart rate monitoring.
- Power Supply and Power Cord: For system operation.
Please note that a host computer (required for the Twin PSG record and review software) and a monitoring cart are sold separately.
Is the Grass Comet system truly portable?
Yes, the Grass Comet Portable EEG/PSG System is specifically engineered for clinical mobility and flexibility. It features a compact, rugged, and lightweight design, making it highly suitable for transport and easy placement. The system is ideal for:
- Mounting securely onto a dedicated mobile cart (sold separately).
- Placement directly adjacent to a patient’s bedside in clinical environments or sleep labs.
Its construction prioritizes durability and ease of use in diverse settings.
Does the amplifier have integrated diagnostics?
Yes, the Grass Comet system’s AS40 (or AS40-PLUS) amplifier is equipped with integrated diagnostics to ensure high-quality, reliable data acquisition in clinical settings.
These diagnostic and control features are accessed directly via the amplifier’s on-board LCD screen and include:
- Electrode Impedance Checking: Allows for immediate verification of proper electrode connection.
- Amplifier Calibration: Built-in routines for maintaining measurement accuracy and signal integrity.
- Photic Stimulator Control: Enables direct management of the photic stimulation process.
- Status Display: Shows crucial real-time information, such as host connection status and pulse/SpO2 readings (when using the optional oximeter).
Additionally, the system features on-board Analog-to-Digital (A/D) Conversion, which minimizes interference and helps ensure the highest quality recordings.
Does the system have built-in safety features for patients?
Yes, the system includes patient safety isolation to ensure patient well-being during monitoring.
Does the system include integrated pulse oximetry?
Yes, the Grass Comet Portable EEG/PSG System supports integrated pulse oximetry, which is critical for comprehensive physiological monitoring, especially during Polysomnography (PSG) studies.
This optional feature allows for the monitoring of:
- SpO2 (peripheral oxygen saturation)
- Heart Rate
When configured for PSG, the system typically includes necessary components like the Nonin XPOD SpO2 Adapter. The amplifier’s on-board LCD screen is capable of displaying this oximetry and pulse rate information.
Does the amplifier feature integrated impedance checking?
Yes, the Grass Comet Portable System is designed with integrated diagnostic functions directly on the amplifier unit. This functionality allows for essential checks to be performed quickly and efficiently without relying solely on the host computer.
On-board functions accessible via the amplifier’s dedicated LCD screen include:
- Electrode Impedance Checking: Critical for verifying excellent electrode contact quality before starting any study.
- Amplifier Calibration
- Photic Stimulator Control
This integration ensures a streamlined, verified, and accurate setup for both EEG and PSG applications.
Does the system offer easy electrode placement?
Yes, the Grass Comet Portable EEG/PSG System features a user-friendly design with easy, identifiable electrode inputs. It includes a clear head and body diagram layout to simplify electrode placement for both EEG and PSG applications.
Does the system offer reliable high-fidelity data transmission?
Yes, the Grass Comet system is engineered for exceptional signal integrity. It features on-board analog-to-digital conversion, which minimizes interference by processing signals directly at the amplifier. This ensures you receive clean, high-quality data recordings essential for precise clinical diagnostics. Furthermore, the system utilizes stable TCP/IP Ethernet connectivity for seamless communication with your host computer.
