ResMed 61723 Quattro FX FFM Replacement Nasal Cushion Large

ResMed 61723 Quattro FX FFM Replacement Nasal Cushion Large

• Model: 61723
• Size: Large

The ResMed 61723 Large Quattro FX cushion is designed to deliver comfort and seal stability for users requiring a larger cushion frame. Its dual‑wall “Spring‑Air” configuration is central to its performance: the inner wall gives structural support to resist collapse at higher pressures, while the softer outer membrane adjusts to facial movement — for example, when turning your head or changing sleep positions — reducing the chance of leaks. The outer membrane’s ability to “roll” around the nose rather than stretching over it helps reduce pressure points and skin irritation, a common complaint in full face mask users. The cushion is made of soft silicone, which conforms relatively gently to facial features, and being latex‑free helps reduce risk of allergy reaction in sensitive users.

Because cushions are consumable parts, the Large size 61723 is especially important for people whose medium or smaller cushions cause tightness, redness, or leak problems due to frame/cushion mismatch. Proper fit between the cushion and frame is crucial: using the correct size ensures that the cushion’s sealing surface aligns properly with the face, headgear tensions are balanced, and mask weight and bulk are distributed more comfortably. The Quattro FX design involves different frames for different sizes, so having the correct match—Large cushion with Large frame—is necessary for the best performance. Using the wrong size tends to lead to leaks, discomfort, or reduced therapy effectiveness.

In clinical or home use, users report that replacing their Quattro FX cushion with a fresh 61723 Large helps restore the mask’s seal, reduce irritation, and sometimes even reduce the need to overly tighten headgear (which can lead to sore spots). Daily cleaning, gentle handling, and inspecting for signs like silicone becoming shiny, creased, or less elastic are important because those aged or worn cushions are typically the weak link in mask leaks. While the Large cushion covers more facial area (which increases internal volume and potential for more “dead space” than nasal masks or smaller masks), ResMed’s design tries to keep that minimized. Still, some users may notice slightly more noise or breathing volume feel than more minimal masks — balancing comfort, seal, and therapy settings is part of getting the best results with this cushion.
