Diese Studie konzentriert sich auf die Bestimmung der Keimbelastung von Sauerstoffmasken, die von drei verschiedenen Unternehmen hergestellt werden, sowie auf die Dosisoptimierung von Gammastrahlung zur Beseitigung der Keimbelastung. Die Keimbelastung wurde durch morphologische Analyse mittels Gram-F�rbung und biochemischer Charakterisierung mit API 20E-Streifen ermittelt. Die Ergebnisse best�tigten das Vorhandensein von drei verschiedenen Bakterienarten: Bacillus subtilis, Staphylococcus epidermidis und Staphylococcus aureus. Die Sauerstoffmasken mit der h�chsten Keimbelastung wurden an Pakistan Radiation Services (PARAS) geschickt, um dort mit drei verschiedenen ausgew�hlten Dosen von 20 kGy, 25 kGy und 30 kGy bestrahlt zu werden. Obwohl f�r die Sterilisation von medizinischen Einwegprodukten eine Dosis von 25 kGy empfohlen wurde, wurde in diesem Fall eine wirksame und vollst�ndige Beseitigung der Keimbelastung mit einer Dosis von 30 kGy erreicht. Unsachgem� sterilisierte Sauerstoffmasken sind f�r Sekund�rinfektionen bei immungeschw�chten Patienten verantwortlich. Daher tragen sterilisierte Sauerstoffmasken durch optimierte Gammastrahlung dazu bei, den Standard der �ffentlichen Gesundheit zu erh�hen, indem sie das Infektionsrisiko verhindern.
