4. Affix programmer head in optimal (good) position.
5. Confirm communications signal strength in all sleep positions.
Place Programmer Cable in Night Mode (Optional)
Full programmer cable lighting may disrupt a patient’s sleep. To disable and dim programmer cable lighting:
1. Turn on the programmer.
2. Select Night Mode from the Start screen.
Start Session
Start a session by connecting to the generator.
Review Therapy Status
Review the information displayed in the Therapy Status section of the Home screen. Note usage hours and any
amplitude changes that the patient has made since the last visit, which are indicated by gold change flags. Talk to
the patient to assess how effectively the patient is using the therapy.
Start Sleep Study Workflow
From the Home screen select Start for the Sleep Study Workflow.
Setup
1. Once the PSG recording has started, use the arrow buttons to select the test stimulation amplitude value.
It is recommended to start the sleep study 0.2 V below the incoming amplitude.
2. Select the Test Stimulation button to deliver one burst of stimulation at the selected amplitude. Confirm
that the stimulation is visible on the chin or submental EMG signal.
3. Determine inhalation and exhalation on PSG. During bio-calibrations, identify the direction of inhalation
on the PSG flow sensors.
Note: It is recommended to have both a nasal pressure canula and a nasal/oral thermistor to reliably
determine inhalation from exhalation during the sleep study.
4. Select Set Amplitude to program the amplitude.
Note: Amplitudes that are set are different from amplitudes that are configured. To set an amplitude is to
make a temporary change. The amplitude will return to its starting value when the sleep study is ended or
when the workflow is exited.
5. Select the Next Step button.
6. If desired, change the programmer cable lights mode.
