Resource Profile: MII PR ICU Parameter von Beatmung

Official URL: https://gematik.de/fhir/isik/StructureDefinition/mii-pr-vent-icu-parameter-von-beatmung Version: 6.0.0-rc
Active as of 2026-04-02 Computable Name: MII_PR_ICU_Parameter_Von_Beatmung

Die Datenstruktur wurde dem laufenden Stand der Entwicklung des MII ICU Module entnommen - https://github.com/medizininformatik-initiative/kerndatensatzmodul-intensivmedizin/blob/master/input/fsh/profiles/Beatmungswerte - Details zur Kompatibilität mit dem ISiK Package der Stufe 6 wurden angepasst und Metadaten des Ursprungsschemas zum Teil entfernt. Stand 16.03.2026
