Factors influencing compliance with continuous positive airway pressure ventilation in obstructive sleep apnea syndrome

Factors affecting compliance with positive airway pressure therapy in obstructive sleep apnea

OBJECTIVE

To investigate the factors affecting compliance with positive airway pressure (PAP) therapy and establish the relationship between compliance and pulmonary function tests (PFT) in patients with OSA.

MATERIAL AND METHODS

In this prospective study, patients with OSA using PAP devices were questioned about the complaints related to the device. Depression and anxiety scales along with PFT parameters were also assessed.

RESULTS

Of 98 participants, 63% were men. The mean age was 52.0 ± 9.6 years. Sixty-seven percent of the patients were compliant with their devices. A significant difference was observed between the proportion of the participants compliant or non-compliant with the device, based on OSA severity (p < 0.05). Beck depression inventory (BDI) and Beck anxiety inventory (BAI) scores of the compliant patients were significantly lower than those of the non-compliant patients (p < 0.001, p = 0.044, respectively). No statistically significant difference was detected between the groups regarding individual pulmonary function tests (p > 0.05). The rates of nasal mask use, not having difficulty in tolerating CPAP, falling asleep, absence of abdominal distension, no facial sores, no air leakage, patients benefiting from the device, reduction in daytime sleepiness, and the belief that they are receiving appropriate therapy in participants compliant with the device were higher than those in non-compliant participants (p < 0.05). The rates of claustrophobia and discomfort due to pressure were significantly lower in patients compliant with the device than in the non-compliant patients (p < 0.05).

CONCLUSION

While no relationship was detected between PFT parameters and PAP therapy compliance, significant factors affecting the device compliance were detected.

The clinical efficiency of positive airway pressure treatment

OBJECTIVES

The aim of this study was to evaluate the clinical efficiency and compliance of positive airway pressure (PAP) treatment.

MATERIALS AND METHODS

This study was conducted on moderate-severe obstructive sleep apnea syndrome (OSAS) patients who admitted to Ankara Numune Hospital Sleep Center between 2008 and 2012. Seventy-five patients with moderate-severe OSAS who were using PAP treatment regularly were enrolled in the study. Patient's usage data, Epworth sleepiness scale (ESS) scores, and the differences in complaints of OSAS were recorded.

RESULTS

The overall complaints were improved when compared to pretreatment period. Particularly there was improvement in apnea, snoring, excessive daytime sleepiness, fatigue, and sleep quality.

CONCLUSION

PAP is effective in reducing symptoms in people with moderate and severe OSAS. To inform the patients with details and the creation of strategies for close followup are necessary for improving the compliance of the patients.
