CeVOX Technologie
CeVOX Technologie
Kontinuierliche Überwachung der zentralvenösen Sauerstoffsättigung
Die CeVOX Technologie basiert auf der Spektrophotometrie
Überblick
Der ScvO2-Wert liefert schnelle Informationen über den hämodynamischen Status des Patienten. Der ScvO2-Wert reagiert deutlich sensibler als Blutdruck und Herzfrequenz auf Schockzustände jeglicher Genese.
Bewährt für
- Notaufnahme [1], [7], [8]
- Septischer Schock [9], [10], [11], [12], [13]
- Frühzeitige zielgerichtete Therapie [7], [8], [14]
- Kardiogener Schock [15], [16], [17]
- Verbrennungen [18], [19], [20]
- Perioperatives Monitoring bei Herz-OPs [21], [22], [23], [24], [25]
- Postoperatives Monitoring [4], [5], [26], [27], [28], [29], [30]
Verbrauchsmaterial
CeVOX Sonde
- Kontinuierliche Glasfaser-Oxymetrie
- Komfortable Anwendung
- Zugang über bestehenden Standard-ZVK
- Einfache Platzierung
- ScvO2-Wert sofort verfügbar
CeVOX Sonden können in das distale Lumen von 15, 20 oder 30 cm ZVKs eingeführt werden, die für Führungsdrähte ≥ 0,08 cm geeignet sind.
Methodik
Die Spektrophotometrie ist die quantitative Messung der Reflexionen oder Übertragungseigenschaften eines Materials als Funktion der Wellenlängen des Lichts. Die CeVOX Technologie verwendet diese Methode, um eine kontinuierliche Messung der Sauerstoffsättigung des Bluts zu ermöglichen. Dazu wird eine CeVOX Sonde mit integrierter Glasfaser in ein Blutgefäß, meist eine Zentralvene, eingeführt.
Ein optisches Modul emittiert Infrarotlicht mit spezifischen Wellenlängen und überträgt dieses durch eine Glasfaser in das Blutgefäß. Das Licht wird von den roten Blutkörperchen reflektiert und durch eine separate Glasfaser an das optische Modul zurückgeleitet, wo es von einem Sensor analysiert wird.
