What is Obstructive Sleep Apnea Syndrome (OSAS)?

characterized by repetitive episodes of upper airway obstruction occur during sleepassociated with a reduction in blood oxygen saturation

Continuous Positive Airway Pressure (CPAP)

Treatment for OSAS

The Myth of Good CPAP Compliance…

Ideal CPAP usage pattern– Use CPAP at effective pressure– During sleep (night/day)– Everyday of the week

In reality, 40-50% of patients do not comply

Reasons for poor compliance

Low patient acceptance/motivation, Early technical problemsInadequate education Limited resource for early close monitoring

Fatal consequences of CPAP Non-Compliance

Fatal RoadAccident

Worsening ofRespiratory

Failure

M yocardialInfaraction

Stroke

Conclusion:

Nurse-led Multifaceted Intervention: Improved CPAP complianceImproved daytime sleepinessDecreased demand on specialist outpatient clinic

Patients are not the only benefactors of good compliance …. The Healthcare System also benefits through reduction of hospital admissions for related cardiovascular diseases
