Understanding CPAP, APAP, and BiLevel Therapy for Obstructive & Complex Sleep Apnea

Discover how modern continuous, auto-adjusting, and bi-level positive airway pressure devices deliver tailored therapy for patients with obstructive sleep apnea (OSA) and respiratory insufficiency.

Obstructive Sleep Apnea (OSA) affects millions worldwide, leading to chronic daytime fatigue, cardiovascular strain, and impaired quality of life. Positive Airway Pressure (PAP) therapy remains the gold standard treatment for maintaining upper airway patency during sleep.

Fixed CPAP (Continuous Positive Airway Pressure) delivers a constant pre-set pressure throughout the night. In contrast, APAP (Auto CPAP) devices like the Pulmo Care Prisma SMART continuously monitor breath-by-breath flow limitations and automatically titrate pressure algorithmically to optimal therapeutic levels.

For patients requiring differential pressures during inspiration and expiration, or those with neuromuscular respiratory weakness, BiLevel S and ST systems (such as Prisma 25ST) provide separate IPAP (Inspiratory Positive Airway Pressure) and EPAP (Expiratory Positive Airway Pressure) settings to ease breathing effort.
