Overview of Alice PDx & Alice 6 zRip Wireset
The Alice PDx zRip wireset (Pack of 2) is a precision respiratory effort sensor interface designed specifically for the Philips Respironics Alice PDx and Alice 6 diagnostic sleep recording systems. Engineered for seamless integration with zRip belts and effort sensors, this wireset provides high-fidelity tracking of thoracic and abdominal respiratory excursions during clinical polysomnography (PSG) studies and home sleep apnea tests.
Key Features & Clinical Benefits
- Enhanced Patient Comfort: Low-profile sensor strap interface minimizes bulk, allowing patients of all body types to sleep naturally during diagnostic recordings.
- Clean Signal Acquisition: Delivers sharp waveform clarity to detect respiratory effort, central apneas, obstructive events, and paradoxes without baseline drift.
- Universal Effort Compatibility: Fully compatible with stretch Velcro® straps and one-size-fits-all CT2 belting solutions.
- Durable Clinical Build: Flexible 1.8-meter lead length equipped with standard 1.5 mm touch-proof safety DIN connectors.
Technical Specifications
- Typical Signal Amplitude: 600 µV peak-to-peak

Dr. Karthik Subramanian –
Accurate phase separation between thoracic and abdominal effort channels. We observed true paradoxical breathing patterns during obstructive events with zero cross-talk or baseline clipping.
Sunita Deshpande –
The 1.8-meter wire length provides enough slack for unrestrained patient turning in bed without tugging the Alice PDx base unit. The snap connectors mate firmly to standard zRIP belts without loose contacts.
Alok Srivastava –
Dual compatibility is seamless across both our portable Alice PDx units and the stationary Alice 6 headboxes. Standard safety pin terminators fit the input ports snugly.
Dr. Meera Nambiar –
Essential diagnostic wireset for reliable RIP effort scoring according to AASM standards. Excellent amplitude response and low noise floor during full Level 1 overnight PSG studies.
Rakesh Patel –
Ordering the 2-pack configuration significantly lowered our per-bed consumable/accessory replacement cost. Fast dispatch and properly protected against static/transit damage.
Kavita Sharma –
Clear color differentiation between thorax and abdomen lines simplifies night-shift patient hookups. Cable insulation is supple and doesn’t kink during coiling.
Manoj Prabhakar –
Tested over 30+ patient studies with repeated wipe-downs using quaternary ammonium disinfectant wipes. The cable jacket and connector strain reliefs remain completely intact.
Dr. Arindam Bose –
Very low motion artifact sensitivity even with restless patients. High signal-to-noise ratio ensures clean respiratory effort waveforms for hypopnea and RERA detection.
