ResMed 61721 Quattro FX FFM Replacement Nasal Cushion Small

• Model: 61721
• Size: Small

The ResMed 61721 (Small) Full‑Face Cushion is designed for users of the Quattro FX or Quattro FX For Her full face masks who need a Small frame. As a full face cushion, it covers both the nose and mouth, which is helpful for people who breathe through their mouth during sleep, have nasal congestion, or need higher pressure therapy. The “Small” size means the frame and cushion are smaller overall, to better fit people with narrower or more compact facial structure. The fit is critical: because the cushion must match the frame size, using the correct Small frame ensures the edges align correctly on the face and that the cushion can seal properly. If it’s too large, issues like leaks or irritation can occur; too small, and pressure/discomfort or gaps may develop.

One of the key design features is the Dual‑Wall Spring‑Air™ cushion. There are two layers: an inner spring‑structured wall to help maintain the cushion shape and support, and an outer membrane/wall that is softer and more pliable to conform to facial contours and adapt to motion during sleep. This helps to maintain a stable seal even if you shift positions, move your jaw, or your mask shifts slightly overnight. The silicone material is soft and flexible but resilient; it inflates a little under the CPAP airflow to help with sealing. These characteristics make it effective at reducing noise, leaks, and pressure points at the skin, as long as the cushion is in good condition and fitted properly. 61721

In practice, the Small Quattro FX cushion offers advantages and trade‑offs. Advantages include good coverage (nose + mouth), relatively stable seal, and comfort through material and cushion design. For people with smaller faces, this size tends to reduce excess bulk, better weight distribution, and less chance of pressure marks or rubbing at the edges. On the downside, full‑face masks are generally larger and possibly more obtrusive than nasal or nasal‑pillow styles. Cleaning needs more care because the cushion contact area is larger, and replacement schedule tends to be frequent (≈ monthly) especially if you notice seal decline, stretching or silicone discoloration. Some users also find that full‑face masks may feel warmer or more confining, especially in hot or humid conditions. Ensuring correct strap tension (not too tight), proper alignment, and maintaining the cushion condition are important to get the benefits without discomfort.
