PALO ALTO, Calif. - Sleep Solutions says an independent comparative study confirmed that its NovaSom QSG home diagnostic system is a reliable alternative to in-lab testing for obstructive sleep apnea (OSA).
Fifty-one patients with suspected sleep apnea underwent one-night in-lab, simultaneous recordings of polysomnography (PSG) and NovaSom, in addition to self-administering the NovaSom QSG at home for three nights.
The data showed very high agreement between NovaSom QSG and PSG when performed simultaneously in the lab.
In addition, comparing the results of at-home testing using the NovaSom QSG with in-lab PSG, researchers found the NovaSom QSG system to be sensitive and reliable for at-home diagnosis of OSA.
The latest study corroborates an earlier published clinical study conducted at the University of California, San Francisco, which showed sleep data obtained simultaneously using the NovaSom QSG and in-lab PSG confirmed the reliability of the system for diagnosing OSA. HME
