Excellent design

Sleep apnea is a condition that requires permanent surveillance. The Alice PDx is your gate towards a professional follow-up from the comfort of your own home, with an outstanding design, winner of the 2010 Medical Design Excellence Awards (MDEA) competition.

Simple data collection

The data collected in your sleep must be reviewed by your healthcare provider, for this, The Alice PDx came up with a very innovative feature allowing you an easy read of the data thanks to The Good Study Indicator that visually displays the amount of good quality data in 25% increments. This way, you can easily communicate with your doctor who then will decide if the study has to be repeated or not. Thus, saving you the time and effort of repeated visits to the clinic.

Computer data display

The Alice PDx can be directly connected to a computer using the Alice Sleepware software application where you can display both live and pre-recorded data.

Color-coded labels

We know how challenging it can be to connect the various sensors alone. The Alice PDx has made it simple for you. With color-coded labels on the perimeter of the device, an intuitive display, and a color-coded step-by-step diagram, sensor placement has never been easier!

Multi-night recording

The Alice PDx comes with an SD card and a 2-3 night battery life for an optimum experience whenever a multi-night recording is required. The recording can be set to start and stop automatically, making sure you have all the care you need even when you forget it.
