Description

PSG Sphinx sleep system delivers reliable and accurate polysomnography recording for modern sleep laboratories. It supports full AASM channel requirements and simplifies patient monitoring during sleep studies. As a result, clinicians can perform detailed analysis with confidence and clarity.

Moreover, PSG Sphinx integrates an intercom, built-in SpO₂, and a pressure transducer directly into the headbox. Because of this design, the system allows easy communication with patients while recording synchronized audio and physiological data. Therefore, technicians can manage studies efficiently without additional external devices.

In addition, PSG Sphinx uses a single Ethernet connection for patient data, intercom, and audio transmission. This connection supports distances up to 100 meters and also allows IP-based system configuration. Consequently, installation becomes simple, clean, and well-suited for fixed or wall-mounted setups.

Furthermore, the system includes six DC input channels that can expand up to fourteen channels when required. These inputs allow integration with external medical devices for advanced sleep diagnostics. As a result, PSG Sphinx adapts easily to both standard and complex study protocols.

PSG Sphinx also features a quick-disconnect system that supports patient movement without signal interruption. Because the SpO₂ sensor and pressure transducer remain part of the headbox, the system maintains signal stability during position changes. Therefore, patient comfort improves without compromising data quality.

Additionally, the single-port pressure transducer measures both CPAP pressure and airflow accurately. The innovative SpO₂ technology delivers dependable oximetry results throughout long recordings. As a result, clinicians receive consistent data even during extended sleep studies.

Finally, PSG Sphinx offers excellent signal performance with a CMRR of ≥100 dB and a filter bandwidth ranging from 0.072 Hz to 300 Hz. Combined with rugged build quality and logical color-coded channel layout, the system ensures long-term reliability and ease of use in clinical environments.
