Löwenstein (prisma series) data comes out of prismaTS, and there are two shapes of it. Both are supported, and you do not need to convert between them. A DCM folder exported from prismaTS — select the folder (or the card/folder that contains it). A dcm.zip archive — upload the zip as it is. Do not unpack it first; the importer reads the archive directly. Notes specific to these machines A zip that contains programs is normal. Löwenstein's own exports bundle vendor support files alongside the data. The upload scanner is built to expect that and lets the archive through — you do not need to strip anything out. The model is decoded from the file, not from the box. The prisma range covers CPAP, auto, bilevel and S/T modes, and the mode determines which channels and which pressure settings appear afterwards. A prisma bilevel will show pressure rows a prisma CPAP does not, and that is correct. Big exports. Long prismaTS exports can be large; if one exceeds the per-upload limit, export it in shorter date ranges and upload them one after another. They merge. Re-exporting the same range is safe — duplicates are skipped. If a prismaTS export is refused or lands in DropBox review, say which prisma model and which prismaTS version produced it. That pair is usually the whole answer. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.
