Introduction
The Sleep apnea screen meter is a device for testing and analyzing patients with Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS). It can detect physiological parameters such as nasal respiratory airflow, thoracic-abdominal respiratory movement, SpO2, pulse rate, body position, etc. The stored cases can be uploaded to the computer by the USB cable for analyzing, which assists medical personnel in evaluating patients’ sleep quality and provides a basis for the medical personnel to formulate diagnosis and treatment plan for the patients with sleep breathing diseases.

Function
1) SpO2 data acquisition
