The letter is the published assessment. Missing factor evidence is labeled; it does not become a zero.
Why this grade
ResMed gates internal repair: proprietary ResMed service/calibration software is required to test and recalibrate AirSense 10/11 and S9 devices after most internal part swaps, and that software, factory tools, and internal parts are made available only to authorized service centers, not to owners or general independents. The clinician/service menu is locked, and ResMed does not sell internal board-level parts to consumers. Offsetting positives keep it above the medical-imaging OEMs: external consumables (masks, filters, tubing, water chambers) are widely sold; iFixit hosts free ResMed repair guides; and ResMed has authorized at least one independent factory-authorized warranty center (Repair Authority) for HME dealers, so a limited sanctioned independent channel exists. Net: still F, but the least restrictive of the four on consumer-level parts.

Methodology & scope
Five dimensions are scored 0–100 and weighted equally: parts availability, schematic access, repairability, OEM pricing and software freedom. The letter scale is A (90–100), B (80–89), C (70–79), D (60–69), F (below 60).
This assessment was last assessed Jun 9, 2026. Its assessment scope is Medical & mobility and is not a claim about every device the maker ships.
