Alice 6 Body Position Sensor

Overview of Alice 6 Body Position Sensor

The Alice 6 body position sensor is an authentic clinical diagnostic transducer engineered specifically for the Philips Respironics Alice 6 polysomnography sleep recording system. Designed with precision internal gravity switches, this diagnostic sensor outputs a continuous signal directly proportional to the patient’s real-time sleep posture (supine, prone, left lateral, right lateral, or upright/sitting). This accurate positional feedback allows sleep clinicians to evaluate position-dependent sleep apnea and positional obstructive events during overnight polysomnography (PSG) testing.

Clinical Importance in Sleep Diagnostics

Position-dependent obstructive sleep apnea (POSA) is characterized by a disproportionate frequency of respiratory events while a patient sleeps in the supine position. The Alice 6 body position sensor delivers real-time posture correlation against oxygen desaturation curves, snore traces, and EEG arousals. By utilizing an accurate sleep posture sensor, diagnostic sleep laboratories eliminate ambiguity when scoring positional hypopneas and respiratory disturbance indices (RDI).

Key Features & Technical Specifications

• Multi-Position Detection: High-precision internal gravity mechanism accurately differentiates between Supine, Prone, Left Lateral, Right Lateral, and Upright positions.
• Ergonomic Low-Profile Casing: Compact, smooth-edged enclosure prevents localized skin pressure and maximizes patient tolerance during sleep studies.
• System Integration: Engineered for plug-and-play synchronization with Philips Respironics Alice 6 headboxes and Sleepware G3 diagnostic software.
• Secure Belt Interface: Features a durable back-clip design that slides effortlessly onto standard thoracic effort belts without slipping during positional shifts.
• Flexible Medical-Grade Lead: Reinforced shielding prevents artifact interference from adjacent EEG, ECG, and EMG channels.

Patient Application & Placement Guide

To ensure flawless positional data acquisition with the Alice 6 body position sensor:

1. Fasten the thoracic respiratory effort belt securely around the patient’s chest at the level of the mid-sternum.
2. Attach the body position sensor to the center anterior section of the belt with the upright orientation marker facing upward towards the neck.
3. Ensure the sensor lies flat against the sternum to prevent tilting that could register false lateral signals.
4. Connect the lead wire to the designated position sensor input channel on the Alice 6 headbox interface.
5. Perform a clinical signal calibration check (asking the patient to verify Supine, Left, Right, and Sitting postures in Sleepware G3) prior to initiating the overnight recording.

Cleaning, Care & Maintenance

Maintaining the Alice 6 body position sensor properly ensures prolonged sensor life and accurate gravity-switch movement:

• Clean the outer casing and cable using hospital-grade surface wipes or a soft cloth dampened with 70% isopropyl alcohol after every patient study.
• Do not autoclave, submerge the sensor housing in water, or expose connectors to direct liquids.
• Store the sensor loosely coiled in a protective compartment to prevent mechanical stress on internal switches.

Frequently Asked Questions (FAQs)

Is this sensor compatible with both adult and pediatric patients?
Yes, the lightweight, compact profile makes it fully suitable for both adult and pediatric clinical sleep investigations when mounted on an appropriately sized thoracic belt.

Does this position sensor require external battery power?
No, the sensor receives operating voltage directly via the Alice 6 headbox interface port.

What is the standard delivery timeline for international orders?
Orders are packaged in secure protective materials and dispatched within 24 to 48 hours via FedEx and DHL Express with full global tracking provided.
