Trotz Erw\u00e4hnung in nationalen sowie internationalen Leitlinien ist die praktische Anwendung der ApOx in Deutschland bisher nicht wissenschaftlich erfasst.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Ziel der Arbeit<\/jats:title>\n            <jats:p>Die vorliegende Studie verfolgt das Ziel, die praktische Anwendung der ApOx in deutschen Kliniken aller Versorgungsstufen zu evaluieren.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Material und Methoden<\/jats:title>\n            <jats:p>Zwischen 01.07.2024 und 03.09.2024 erfolgte eine multizentrische, explorative, anonyme Befragung der An\u00e4sthesisten in verschiedenen deutschen Kliniken.

Die Mehrheit der Teilnehmer war m\u00e4nnlich (63\u202f%), mit einem Durchschnittsalter von 41\u00a0Jahren (\u00b1\u202f10,4). Die Verteilung der Karrierestufen zeigte das folgende Bild: Oberarzt (34\u202f%), Arzt in Weiterbildung (34\u202f%), Facharzt (25\u202f%), Chefarzt (8\u202f%). In 84\u202f% der F\u00e4lle konnte festgestellt werden, dass weder innerklinisch noch pr\u00e4hospital eine Standardarbeitsanweisung zur ApOx existierte. In der vorliegenden Studie gaben 18 % der An\u00e4sthesisten an, die ApOx regelm\u00e4\u00dfig durchzuf\u00fchren. Die Anwendung erfolgt in den folgenden Situationen: 54\u202f% \u201erespiratorische Insuffizienz\u201c, 42\u202f% \u201eerwartet schwieriger Atemweg\u201c und 34\u202f% \u201eNotfallnarkose\u201c.
