In a March 16, 2026 episode of the LowCarbMD podcast, Dr. Tro spoke with Dr. Alan Schaffer, a sleep and pulmonary medicine physician at St. Peter’s Sleep Center. One practical moment in their conversation addresses a concern many people have before trying CPAP: what wearing the mask will actually feel like.

Watch the CPAP mask demonstration
In this two-minute excerpt, Dr. Tro asks about the bulky “Darth Vader” image some patients have of CPAP. Dr. Schaffer shows the nasal-cushion mask he uses, including the cushion at the nose and the hose connection above his head. He also explains why showing patients the equipment can make a conversation about treatment easier. This is his example of one mask, not a recommendation that the same setup fits everyone.

Why this conversation matters
A treatment can sound intimidating before someone sees what it involves. In the clip, Dr. Schaffer responds to that hesitation by showing a real mask and answering a practical question. The next step for any individual depends on their own sleep evaluation and discussion with a clinician.
Sleep apnea is only one possible reason sleep is disrupted. If you snore loudly, wake gasping, or feel sleepy while driving, those symptoms deserve attention. Our guide, Better Sleep Is Part of Better Metabolic Health, explains how to recognize sleep problems and build a broader plan for rest and metabolic health.
