Respironics Alice PDx Portable Sleep Diagnostic System

Respironics Alice PDx Portable Sleep Diagnostic System Features

• Powered by Sleepware G3: The Sleepware G3 is the same software used by the Alice family in-lab PSG and portable sleep diagnostic devices. It is a robust platform with enhanced functionality to help busy sleep labs better meet their business and workflow needs, regardless of their lab size.
• Single Software Application Streamlines Data Collection: The PDx can be connected directly to a computer running the proven Alice Sleepware software application. Alice Sleepware can display live or pre-recorded data in a resolution consistent with the computer hardware specifications. It provides a single software application for lab and portable testing.
• Color-Coded Labels to Reduce Retesting: The Alice PDx interface is easy to use, easy to understand, and informative. There are color-coded labels located around the perimeter of the device that indicate where to connect the various sensors. The display shows the patient only the sensors that need to be connected. The sensor information and indicators help your patient place the sensors correctly and reduce the need for retesting due to application errors. There is a helpful, color-coded, step-by-step diagram included to walk patients through the appropriate application process. The base configuration channel set supports testing requirements for levels 3 and 4, and includes: nasal pressure cannula, oral thermistor, zRIP abdominal and chest belts, SpO₂, and body position.
• Multi-Night Recordings: With the SD card memory and two to three-night battery life, the Alice PDx can collect information from multi-night recordings when needed. It can be set to start and stop recording automatically to minimize the risk of the patient forgetting to set it.
• Good Study Indicator Confirms Quality Data Recorded: The GSI is predicated on airflow and oximeter signal quality and displays the amount of "good quality data" needed for a study to be complete and valid. The GSI visually displays the amount of good quality data in 25-percent increments on the PDx display screen. This information allows the clinician to decide if the patient needs to repeat the study. If the study needs to be repeated, the provider can educate the patient remotely on how to apply the sensors better.
