Changes of Ventilator Generated Volume and Pressure under Simulated Cabin Pressure Profiles of Military Aircraft C160 Transall.

摘要

Pulmonary traumata and special intensive care therapies often lead to a respirator treatment. After stabilization of the patient vital functions in the medical installations of the operation area the respirator treatment has to be continued during the air-transport for repatriation. Patient and ventilation equipment are exposed to certain influences caused by the air-transport. Originally respirators are built for the use on the ground (air-pressure 1013 mbar) only changes (+1- 20 mbar)in air-pressure. The aim of this study was to examine the influence of cabin pressure on important parameters of ventilation using different transport ventilators. Simulating cabin pressure conditions, differences in the applied tidal volume and PEEP to a preset value were to be determined.
