CPAP Titration

Course Objectives

Upon successful completion of this module, you will be able to:

• Synthesize comprehensive knowledge of positive airway pressure (PAP) therapy modalities including continuous positive airway pressure (CPAP), auto-adjusting positive airway pressure (APAP), bilevel positive airway pressure (BPAP), and adaptive servo-ventilation (ASV), understanding the physiological mechanisms, clinical indications, contraindications, and evidence-based selection criteria for each modality in diverse patient populations as of 2025.
• Apply the American Academy of Sleep Medicine (AASM) clinical practice guidelines and scoring manual requirements for PAP titration studies, including patient preparation protocols, equipment setup and calibration, initial pressure determination, systematic titration algorithms, response to residual events (apneas, hypopneas, RERAs, snoring, desaturation), pressure adjustment strategies, and documentation requirements ensuring compliance with accreditation standards.
• Evaluate titration study outcomes and determine optimal therapeutic pressure through interpretation of polysomnographic data including apnea-hypopnea index (AHI), respiratory disturbance index (RDI), oxygen saturation patterns, sleep architecture, arousal index, and patient tolerance factors, distinguishing between adequate titration, suboptimal titration requiring repeat study, and complex sleep apnea requiring alternative therapeutic approaches.
• Demonstrate proficiency in troubleshooting common PAP titration challenges including mask interface issues (leak, discomfort, skin irritation, claustrophobia), pressure intolerance (aerophagia, exhalation difficulty, sinus pressure), persistent respiratory events despite pressure increases, central apneas emerging during titration, positional variations in therapeutic pressure requirements, and patient non-cooperation or premature study termination.
• Compare and contrast alternative titration methodologies including full-night attended in-laboratory titration, split-night diagnostic/titration protocols, autoCPAP algorithms for unattended titration, empiric pressure setting approaches, and home-based titration strategies, understanding the evidence supporting each approach, appropriate patient selection criteria, advantages and limitations, cost-effectiveness considerations, and implications for clinical practice and patient outcomes.
• Analyze special populations and clinical scenarios requiring modified titration approaches including pediatric patients, patients with comorbid cardiopulmonary disease (COPD overlap, heart failure), obesity hypoventilation syndrome, neuromuscular disorders, positional or REM-predominant sleep apnea, complex sleep apnea or treatment-emergent central apneas, and patients with multiple interface or pressure intolerance issues, applying evidence-based strategies tailored to specific clinical contexts.
• Integrate knowledge of PAP therapy optimization and adherence facilitation into the titration process, recognizing that successful titration extends beyond identifying therapeutic pressure to include patient education, interface optimization, humidification and climate control adjustment, comfort feature utilization (pressure relief, ramp), addressing psychological barriers, and coordinating post-titration follow-up care to maximize long-term therapeutic adherence and clinical outcomes.

Course Information

CPAP stands for continuous positive airway pressure. Nasal CPAP therapy is a non-invasive, non-surgical way to treat obstructive sleep apnea.

When a patient comes into the Sleep Center to be titrated on nasal CPAP, he or she is fitted with a relatively small, comfortable mask that goes over the nose only. This mask is hooked up to a CPAP unit, which delivers an air pressure through the nose into the back of the airway to splint the airway open during sleep with air. Initially, the CPAP unit uses a low air pressure that allows patients to breathe easily in and out against the slight pressure. When the patient is asleep, the pressure is adjusted (titrated) to keep the back of the airway open during sleep. Pressure is titrated to keep the patient apnea-free in all stages of sleep and in all body positions. The CPAP allows the patient to achieve restful and deep sleep without interruption during the night. Patients with sleep apnea not only get a good night’s sleep on CPAP therapy, but also prevent long-term damage to their heart and body that could be caused by lack of oxygen and poor sleep.
