The ApneaCheck product is currently in prototype stage. The clinical study below suggests that ApneaCheck may be a very useful screening tool for detection of the Sleep Apnea Syndrome in the home environment. They are not designed for unattended use. A trained technician must come to the patient's home to aid in setting up and disconnecting the system and retrieving the data.
Most systems require analysis of the data by highly trained professionals.
The data is downloaded to a computer and automatically scored for identification of SDB events. The purpose of this study was to evaluate the capability of the ASSR system to detect SDB events in patients with a range of sleep apnea rates and more particularly, evaluate the ability of the airflow recorder to capture, identify and count apneic events. The scoring of SDB events from the PSG data was then compared to the automated computer scoring of the ASSR data. The PSG and ASSR data were analyzed for point by point agreement for airflow, and thoracic and abdominal respiratory effort. In addition, overall agreement across subjects for SDB rates from the PSG and ASSR data were compared for thoracic effort combined with airflow and for airflow alone.
