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.
