This study looks at the quality of the common mechanisms used to diagnose obstructive sleep apnoea (OSA) by patients in their own homes. These are pulse oximetry as a stand alone measurement and multi-channel respiratory studies that measure oximetry but also record some combination of signals including airflow at the mouth and or nose, chest and abdominal expansion, body position and snoring. This study will examine the patient acceptability of these methods and the proportion of studies that achieve various levels of technical quality ranging from a full night with all data available to a completely failed study and categories in between.
