Sleep analysis with Alice PDx

A new recording device enables clinicians to diagnose and treat sleep disorders through remote monitoring.

The Alice PDx Portable Sleep System from Royal Philips Electronics is a diagnostic recording system for Obstructive Sleep Apnea (OSA) diagnosis and follow-up, and diagnostic assessment of cardio-respiratory sleep disorders.

The compact system satisfies the portable testing requirements for levels II, III and IV, and can be used for basic screening or more complex diagnostic evaluation. It can be used in the patient’s home, a care site or a sleep lab.

The Alice PDx enables patients to be tested outside the lab without compromising the accuracy of the data. A built-in Good Study Indicator helps clinicians to determine the validity of the data collected. Remote testing and data verification both help to avoid costly and time-consuming retests.

The system is easy for patients to set up and use. The wires are designed to minimise excess length. Colour-coded labels indicate which sensors to connect and where to connect the sensor leads. A diagram guides the patient through the application process.

The Alice PDx supports ‘smart card’ connections: a Secure Digital (SD) card captures the data, which is sent to the clinician via a Windows-compatible personal computer. With an SD card, the Alice PDx can collect information from multi-night recordings, and can be set to start and stop recording.

Tim Murphy, Vice President and General Manager, Diagnostics and Clinical Software Applications, said: “We believe the Alice PDx system serves the key operational efficiency, ease of use, and versatility needs of the clinician and patient. Through innovative device features, a unique user interface, and our common diagnostic analysis software, Sleepware, we are able to offer clinicians a complete and quality study.”
