EMDN R90: Respiratory and Anaesthesia Devices - Various
Complete hierarchy for EMDN group R90 in category R (Respiratory and Anaesthesia Devices): 16 terminal codes, EMDN v2026. Terminal codes are the ones accepted in a EUDAMED device record.
Registered classes, as of 8 Sep 2026. For each code with at least 20 registrations under a legislation, the chip shows how devices registered in EUDAMED under that code are classed, counted once per primary UDI-DI and kept separate for each legislation. It is not a determination. The class of a device comes from the MDR and IVDR classification rules for its intended purpose. MDD and IVDD classes are the directive classification and can differ from the class the same device would have under MDR or IVDR.

How R90 is structured
The Respiratory and Anaesthesia Devices - Various branch runs 3 levels deep. 4 entries below are branch headings that group other codes rather than naming a device, so a classification has to resolve all the way down to one of the 16 codes marked terminal.
2 terminal codes are “- Other” entries and 2 are “- Accessories” entries, 25% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.
The largest sub-branch is R9003 (Respiratory System Surgery Instruments, Single-Use), holding 3 of the 16 terminal codes.
Frequently asked questions
- Which R90 codes can be used in a EUDAMED device record?
- 16 of the 20 codes listed under R90 (Respiratory and Anaesthesia Devices - Various) are terminal and can be selected. The other 4 are branch headings that cannot.
- How deep is the R90 hierarchy?
- The R90 branch runs 3 levels below the group code. Its largest sub-branch is R9003 (Respiratory System Surgery Instruments, Single-Use), which holds 3 of the 16 terminal codes.
- How many R90 codes are catch-all entries?
- 2 terminal codes under R90 are "- Other" entries and 2 are "- Accessories" entries, 25% of the branch. The remaining 12 name a specific device type.
