Zusammenfassung

Eine hyperbare Einmannkammer vom Typ Vickers wurde zu erweitertem Monitoring adaptiert. Registriert wurde an einem Schädelhirnverletzten: EKG, Basaltemperatur, zentralvenöse und arterielle Blutgase, blutiger Blutdruck, pneumotachographische Kurve und der Beatmungsdruck. Bei Spontanatmung wurde Anstieg des venösen pO2, des arteriellen pCO2 und des Atemminutenvolumens bei Kompression mit reinem O2 gefunden. Bei Beatmung mit einem Fluid-logic-Respirator kam es zu noch stärkerem Anstieg des arteriellen pCO2 und des venösen pO2 bei Kompression. Anhand der pneumotachographischen Kurven und mittels Beatmungsdruckregistrierung wurde gezeigt, daß der fluid-logic-Respirator in Grenzsituationen und insbesondere bei Verwendung als Assistor am nicht relaxierten Patienten die Beatmung nicht suffizient durchführen kann. Die Interpretation der gefundenen Werte aufgrund der vorliegenden Literatur wird diskutiert. Es wird vor unkontrolliertem Gebrauch des fluid-logic-Respirators gewarnt, und die vorliegende Anordnung für den Einzelfall empfohlen.

Possible methods for fuller monitoring of respiratory parameters in hyperbaric Chambers

Abstract

A small hyperbaric chamber (Vickers) was modified in order to facilitate amplified monitoring. ECG, basal temperature, central venous and arterial blood gases, blood pressure pneumotachygraphy and ventilation pressure were monitored in a cerebral trauma case. With rising pressure in O2 atmosphere rises in venous pO2 and in arterial pCO2 were observed. When the patient was ventilated with a fluid-logic ventilator there was a higher rise in arterial pCO2 and in venous pO2, as hyperbaric atmosphere was gained.

The pneumotachygraphic registration and the ventilation pressure showed, that the fluid logic ventilator can not comply with requirements in critical situations, and especially when used as an assistor.

The interpretation of these findings is discussed in the light of current knowledge in this field. Uncontrolled use of the fluid-logic ventilator is depreciated and the modification of the Vickers chamber is recommended for monitoring in selected cases.
