#### Indications
This procedure is indicated for patients who:
- Use CPAP therapy for sleep apnea.
- Experience discomfort, poor fit, or airflow leaks from their current nasal pillows.
- Need to replace worn or damaged pillows to maintain effective treatment.

#### Preparation

- Clean their hands before handling the replacement pillows.
- Review their CPAP machine's user manual for specific instructions.
