Clinical Definition

Mask interfaces include:

  • Nasal Masks: Cover the nose only
  • Full Face Masks: Cover both nose and mouth
  • Nasal Pillows: Seal at the nostrils
  • Hybrid Masks: Combine nasal pillows with mouth covering
  • Oral Masks: Cover the mouth only (rarely used)

The mask interface includes the mask cushion, frame, headgear, and connection to the PAP tubing. Proper sizing and fitting are essential for therapy success and patient comfort.

Etymology & History

CPAP masks have evolved significantly since the first nasal CPAP devices in the 1980s. Early masks were bulky and uncomfortable, leading to continuous improvements in design, materials, and comfort features.

Reference Values & Interpretation

Normal Values

A properly fitted mask should maintain prescribed pressures with minimal leakage, be comfortable for extended wear, and allow for normal sleep positions and movements.

Abnormal Values

Poor mask fit can result in excessive air leaks, pressure sores, eye irritation, or inadequate therapy delivery. Common problems include over-tightening, wrong size selection, or inappropriate mask type.

How It's Measured

Mask interface effectiveness is assessed through leak data from the PAP device, residual AHI, patient comfort reports, and clinical evaluation for pressure marks or skin irritation.

Role in Diagnosis

Proper mask interface selection and fitting are crucial for PAP therapy success. The mask type and size must be appropriate for the patient's facial anatomy and breathing patterns.

Role in Treatment

The mask interface is essential for effective PAP therapy. Proper selection and fitting directly impact therapy success, patient comfort, and long-term compliance with treatment.
