A partial sleep study is a limited version of a whole-night polysomnography (PSG). It has relatively fewer monitoring channels; and those are devoted to respiratory functions. The focus on respiratory functions makes it ideal for diagnosing sleep-related breathing disorders.
It is also a less expensive diagnostic procedure and the data it generates is much easier to score than data produced by a whole-night PSG.
A trend towards greater use of partial sleep studies is underway, though it cannot always replace a full PSG, especially if sleep problems are more complex or not caused only by respiratory disorders.
