Alice Pdx SPO2 compatible Sensor

Overview of Alice PDx SpO2 Sensor

The Alice PDx SpO2 sensor is a premium clinical pulse oximetry probe engineered specifically for the Philips Respironics Alice PDx and compatible sleep recording systems. Designed with an advanced soft-boot, clip-free silicone cuff and dual-wavelength infrared optical emitters, this reusable pulse oximeter probe provides continuous, high-precision arterial oxygen saturation (SpO2) and pulse rate tracking during overnight diagnostic polysomnography (PSG) and home sleep apnea tests (HSAT).

Clinical Accuracy & Desaturation Detection

In sleep medicine diagnostics, pinpointing subtle oxygen desaturations is essential for scoring obstructive, central, and mixed sleep apnea events accurately. The Alice PDx SpO2 sensor features optical components that minimize motion artifacts, signal degradation, and ambient light interference. By ensuring rapid signal acquisition, the probe provides continuous photoplethysmography (PPG) waveforms that correlate directly with airflow limitations and autonomic arousals.

Key Features & Patient Comfort

• Clipless Ergonomic Design: Soft, flexible medical silicone sheath fits snugly around the patient’s digit without the pinching pressure of hard plastic spring clips, preventing ischemic finger discomfort.
• Motion-Resistant Fit: Contoured internal grip conforms to the finger anatomy to prevent slippage and eliminate movement artifacts when patients toss and turn during overnight studies.
• Unrestricted Circulation: Elastic silicone structure distributes contact pressure evenly to preserve natural capillary blood perfusion during extended diagnostic sessions.
• Medical-Grade 2-Meter Cable: Low-noise, shielded 2-meter (6.5 ft) lead wire provides ample slack between the patient interface and the recorder unit while preventing signal crosstalk.
• Category: Alice PDx Accessories and Alice 6 Accessories.

Clinical Placement & Setup Guide

To ensure optimal signal fidelity and accurate plethysmogram curves with your Alice PDx SpO2 sensor:

1. Select an appropriate site (the adult index, middle, or ring finger of the non-dominant hand is preferred).
2. Ensure the selected finger is clean, dry, and free from dark nail polish or artificial nails that may absorb infrared light.
3. Slide the patient’s finger into the soft silicone boot until the fingertip rests flush against the internal sensor stop, aligning the cable along the top of the hand.
4. Secure the cable along the forearm using medical tape to create a strain-relief loop that prevents pulling during sleep.
5. Connect the terminal pin into the pulse oximetry port on the Alice PDx base station and verify a steady plethysmogram pulse trace in Sleepware G3 before initiating the study.

Cleaning, Disinfection & Care

Proper maintenance of every Alice PDx SpO2 sensor protects optical diodes and prolongs product lifespan:

• Wipe the silicone sleeve and entire cable jacket with a soft cloth dampened in 70% isopropyl alcohol or mild hospital surface disinfectant after each sleep study.
• Allow the interior cavity of the silicone boot to dry completely before storing or applying to another patient.
• Do not autoclave, immerse the cable in liquid disinfectant baths, or expose terminal connectors to moisture.
• Store the lead wire loosely coiled without sharp bends or heavy objects resting on the sensor head.

Frequently Asked Questions (FAQs)

Is this sensor compatible with both Alice PDx and Alice 6 systems?
Yes, this probe utilizes the dedicated connector interface that integrates seamlessly with Philips Respironics Alice PDx recorders and Alice 6 system headboxes.

Can this sensor be worn by patients with sensitive skin?
Yes, the clip-free, hypoallergenic silicone casing eliminates localized mechanical pressure points, making it suitable for geriatric and sensitive patients.
