Sleep, breathing, and neurobehavior in COPD: pilot study

Poster presented at the 21st Annual Meeting of the Associated Professional Sleep Societies, Minneapolis, MN.INTRODUCTION: Deficits in neurobehavior have been shown in COPD, possibly associated with the poor sleep and oxygen desaturations experienced by patients. There has been limited exploration of these associations. METHODS: Subjects with COPD (FEV1 < 60% predicted for gender, age, and height) were recruited from a pulmonology clinic during routine visits. Subjects wore an ambulatory pulse oximeter (one day) and accelerometer (one week) and completed a sleep diary. All subjects completed the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), 4 word memory recall test, 10 minute psychomotor vigilance task (PVT), computerized digit-symbol substitution test (DSST), and finger tapping test. RESULTS: Nine subjects have been studied. Sleep quality is below normal. PSQI correlated moderately with number of minutes during sleep SO2 < 88% (r = .45), but minimally with baseline SO2 or the SO2 nadir. Additionally, PSQI had a moderate correlation with FEV1% predicted (r = -.44), but small correlation with FEV1/FVC (r = -.27). Sleep quality also demonstrated small to moderate correlations with neurobehavioral measures, including short term memory (r = -.36), PVT (reaction time r = .69, trend p = .08; lapses r = .59), finger tapping (r = -.46), and executive function (DSST r = -.24). CONCLUSION: This preliminary data suggests that pulmonary parameters are related to sleep quality and neurobehavioral performance. The nature of this relationship will be delineated in the modeling of these variables using a larger sample

Spousal involvement and CPAP adherence: A dyadic perspective

Poor adherence to continuous positive airway pressure (CPAP) treatment is associated with substantial health care costs, morbidity and mortality, and has been a leading obstacle in the effective management of obstructive sleep apnea (OSA). Successful interventions to improve CPAP adherence may ultimately include a variety of components. For patients living with spouses (refers to all domestic partners), the spouse will likely be an integral component to any successful intervention. Developing understanding of the role of spouses in adherence to CPAP has been identified to be a critical research need. This review expands the investigation of CPAP adherence to a broader context, from an exclusive focus on individual patients to a dyadic perspective encompassing both patients and their spouses. A conceptual framework based on social support and social control theories is proposed to understand spousal involvement in CPAP adherence. Methodologies for future investigations are discussed, along with implications for developing interventions that engage both patients and their spouses to improve CPAP use
