Ineffective CPAP Treatment After Effective CPAP Titration.

Area of Science:

• Sleep Medicine
• Respiratory Medicine

Background:

• Obstructive Sleep Apnea (OSA) is a common sleep disorder characterized by repeated upper airway collapse during sleep.
• OSA is associated with significant comorbidities including hypertension and type 2 diabetes.
• Continuous Positive Airway Pressure (CPAP) is a primary treatment for moderate to severe OSA.

Observation:

• A 67-year-old female presented with classic OSA symptoms: snoring, excessive daytime sleepiness (Epworth score 22), frequent awakenings, nocturia, headaches, and witnessed apneas.
• The patient had a history of OSA, hypertension, type 2 diabetes, and mild intermittent asthma.
• Initial CPAP therapy with a nasal mask (ResMed AirFit N20) caused discomfort.

Findings:

• Switching from a nasal to an oronasal mask improved CPAP mask tolerance.
• The patient achieved consistent nightly CPAP use with acceptable tolerance, maintaining 7 hours of total sleep time.
• Despite initial mask discomfort, the patient's OSA symptoms were managed with CPAP therapy.

Implications:

• Mask interface selection is crucial for CPAP therapy adherence and patient comfort in Obstructive Sleep Apnea management.
• Oronasal masks can be an effective alternative for patients experiencing discomfort or intolerance with nasal masks.
• Optimizing CPAP interface can improve treatment outcomes and quality of life for individuals with OSA.
