The Mask That Does Not Fit
CPAP masks come in three basic types: full face, nasal, and nasal pillow. A full-face mask pressed against the bridge of your nose at the wrong angle will leave red marks by morning and a reason to leave the machine on the shelf by the following week. Most Indian sleep clinics hand over whichever mask is in stock rather than fitting one to the patient's face shape. A mask that leaks air pushes pressure into your eyes, dries your mouth, and makes the whole night feel like sleeping in a wind tunnel. The fix is not to abandon the machine. It is to go back and ask for a different interface. Nasal pillows, which rest at the nostrils rather than covering the nose, resolve most leak problems for people who are not heavy mouth-breathers.
