Ambulatory Sleep Recorder
The PL-SLP is a very lightweight and small recorder with 16 analog channels and a serial interface to connect a NONIN finger clip sensor.
- Channels:
– 3x EEG (referential)
– 2x EOG (referential)
– 1x ECG (bipolar)
– 3x EMG (bipolar)
– 3x Body position/movement (internal acceleration sensors)
– 2x Breathing
– 1x Flow (mouth and nose)
– 1x Microphone (snoring) - Digital marker channel for event registration
- Optional NONIN finger clip sensor for:
– 1x Plethysmogram (finger blood pressure)
– 1x Oxygen saturation (percent)
– 1x Pulse rate (calculated from finger pulse signal) - Further options:
– Sensor for registration of environment temperature and humidity
– Higher Processor frequency for higher sampling rates – up to 1600 Hz per channel
– Display showing operation modes and measuring data
– Wireless recorder operation interface (Bluetooth) with PDA, PC or notebook - Data are recorded to a Compact Flash Card
- Sleep stading and further quantitative analyses can be applied after data transfer. In combination with patient event markers, data quantity effectively can be reduced to a minimum.
- Using PL-Winsor, irrelevant data segments easily can be cut, and data can be archived and managed together with standard EEG records.
