Alice PDx EEG Leads

Overview of Alice PDx EEG Leads & Diagnostic Headbox Wires

The Alice PDx EEG leads set is a clinical-grade neurodiagnostic leadwire assembly engineered specifically for the Philips Respironics Alice PDx portable sleep diagnostic system. Designed to interface seamlessly with the Alice PDx EEG/EOG/EMG extended sensor yoke, these high-conductivity lead wires deliver clear, artifact-free electroencephalography traces required for sleep staging, sleep architecture analysis, and micro-arousal scoring during clinical polysomnography (PSG) and home sleep testing (HST).

Clinical Importance & Sleep Staging Accuracy

Accurate neurophysiological sleep assessment relies on acquiring low-amplitude microvolt signals from the scalp without high-frequency interference or baseline sway. The Alice PDx EEG leads are manufactured using premium, low-impedance multi-strand copper alloy conductors shielded by flexible medical-grade jackets. This design preserves critical brainwave frequencies—including delta waves, theta rhythms, alpha background activity, sleep spindles, and K-complexes—essential for differentiating between NREM (N1, N2, N3) and REM sleep stages.

Key Features & Specifications

• Multi-Channel Sensor Compatibility: Configured for standard neurodiagnostic montages including EEG (scalp derivations), EOG (eye movements and blinks), and Chin/Limb EMG (muscle tone and periodic limb movements).
• Precision Safety Terminals: Terminated with standard 1.5 mm touch-proof DIN 42802 gold-plated connectors for secure, zero-noise docking into the Alice PDx yoke.
• Universal Snap & Cup Connectors: Designed for rapid interface with standard Ag/AgCl disposable snap electrodes and reusable gold cup electrodes.
• Flexible Kink-Resistant Insulation: Lightweight, ultra-flexible lead cabling reduces pulling forces on patient facial and scalp attachment sites to minimize movement artifacts.
• Multi-Color Wire Coding: Clear color distinction facilitates quick channel mapping according to the standard 10–20 International Electrode Placement System.
• Category: Alice PDx Accessories and Alice 6 Accessories.

Montage Application & Electrode Placement Guide

To ensure optimal electrode impedance below 5 kΩ using your Alice PDx EEG leads:

1. Thoroughly prep scalp and skin application sites using a mild abrasive prep gel (such as Nuprep) and alcohol to remove natural sebum and epidermal oils.
2. Attach the color-coded snap leads firmly onto fresh silver/silver-chloride (Ag/AgCl) diagnostic electrodes or cup interfaces loaded with conductive paste (Ten20).
3. Position electrodes according to the recommended AASM montage derivations (e.g., F4-M1, C4-M1, O2-M1, with EOG cross-canthal references and submental chin EMG).
4. Insert each 1.5 mm DIN safety pin into the corresponding labeled channel port on the Alice PDx EEG interface yoke.
5. Run an automated impedance calibration test in Sleepware G3 to confirm low baseline impedance prior to beginning the recording.

Cleaning, Care & Disinfection Standards

Proper maintenance of every Alice PDx EEG leads set protects conductor continuity and maintains signal sensitivity:

• Wipe the leadwire jackets and snap terminals clean using 70% isopropyl alcohol wipes or hospital disinfectant solutions after every diagnostic study.
• Never immerse the 1.5 mm DIN connector plugs directly in liquid baths or cleaning basins.
• Do not autoclave or subject cables to high-pressure steam sterilization.
• Store lead bundles loosely looped in hanging racks or storage bags without sharp kinks or tight rubber bands.

Frequently Asked Questions (FAQs)

Can these lead wires also monitor limb movements (PLMD)?
Yes, these multipurpose leads connect to leg EMG electrode placements to record periodic limb movements in sleep.

Are these leads compatible with both Alice PDx and Alice 6 systems?
Yes, the universal 1.5 mm safety DIN connectors fit both the Alice PDx extended EEG yoke and Alice 6 base headboxes.

How fast is dispatch for international clinic orders?
