Obstructive sleep apnoea

Abstract

This chapter covers the causes, signs, and symptoms of obstructive sleep apnoea (OSA). It explains the process of diagnosis, from a history, medications, family, and psychosocial history, occupation, and diagnostic procedures. Differential diagnoses that should be excluded are listed. The prevalence of OSA is estimated to be around 4% of the population. It is quite a common disorder, although this figure may be an underestimate as many people may not seek treatment. Prevalence figures also vary according to the chosen threshold for defining a significant sleep abnormality and symptoms. Treatment options are also outlined, and the specific aspects of nursing care are listed.
