Mask interface for continuous positive airway pressure therapy: selection and design considerations

Area of Science:

• Biomedical Engineering
• Sleep Medicine
• Medical Device Design

Background:

• Continuous Positive Airway Pressure (CPAP) therapy is standard for moderate to severe obstructive sleep apnea (OSA).
• Current CPAP masks are mass-produced, lacking personalization for individual patient anatomy and needs.
• Suboptimal mask fit negatively impacts CPAP therapy compliance and efficacy, potentially causing skin issues.

Purpose of the Study:

• To review conventional CPAP mask design limitations.
• To explore the impact of mask interface on OSA treatment outcomes and patient compliance.
• To investigate emerging trends in customized CPAP devices for improved patient care.

Main Methods:

• Literature search across Scopus, PubMed, and Google Scholar.
• Analysis of reported data on CPAP mask interface influences.
• Review of current advancements in personalized medical device technology.

Main Results:

• Standard CPAP masks do not account for individual patient characteristics like facial topology or skin sensitivity.
• Customized CPAP interfaces offer potential for optimizing mask fit and improving treatment outcomes.
• Technologies like reverse engineering, computational modeling, and additive manufacturing enable personalized mask design.

Conclusions:

• Tailoring CPAP masks to individual patient needs is crucial for effective obstructive sleep apnea management.
• Personalized CPAP interfaces can enhance patient compliance and reduce adverse effects.
• Further integration of enabling technologies is needed for widespread adoption of customized CPAP solutions.
