Obstructive sleep apnoea (OSA) is a chronic syndrome that carries both personal and societal costs.  In OSA collapsibility of the upper airway during sleep leads to repeated momentary cessation of breathing of anywhere between five to >100 times per hour, resulting in repeated micro arousals and associated symptoms such as snoring and hypersomnolence.  The resultant reduction in quality of life has negative impacts on relationships, home and social life.  OSA has a strong association with obesity, is implicated as an independent risk factor for hypertension and cardiac sequelae, and increases the likelihood of occupational and vehicular accidents.  Additionally, evidence indicates one in five overweight US adults have at least mild sleep apnoea.

Night-time continuous positive airway pressure (CPAP) via nasal or face mask, considered gold standard treatment for OSA, acts as a pneumatic splint holding the pharynx open during sleep.  However, CPAP can be painful around the face, may wake the user during sleep, and has associated side effects.  Studies suggest that poor compliance with this therapy remains a concern.  The World Health Organisation suggests that 65-75% of people with OSA are obese (BMI ≥30.0).  The predicted global increase in obesity may therefore lead to an increase in prevalence of OSA.  Exploring management of CPAP from the user perspective is crucial to successful administration of therapy.  The aim of this qualitative grounded theory study is to explore life using CPAP for OSA with both users and users’ spouses to develop a deeper understanding of patients’ perspectives with this therapy.
