SleepTrek^® Portable Sleep Screener

SleepTrek, 9-channel Sleep Screener is a small lightweight physiological data recorder specifically designed to assist the clinician in the diagnosis of sleep-disordered breathing. SleepTrek uses sensors to record oxygen saturation, pulse rate, airflow, thoracic and abdominal respiratory effort, periodic limb movement and body position. The screener is designed to be used in a supervised (hospital/institutional) or unsupervised (home) environment. It is capable of recording 12+ hours of patient data using a single 9-volt alkaline battery and a 16-megabyte MultiMediaCard. An auxiliary channel is also available to record data from other equipment such as pressure from a Continuous Positive Airway Pressure (CPAP) devices. The data collected by SleepTrek is downloaded to EDF file format.
