[Artificial respiration of multi-injured patients with He-O2 and N2-O2 mixtures. II. Hemodynamics].

Multi-injured patients (n = 18) requiring ventilatory support were alternatively ventilated with either He-O2 or N2-O2 mixtures (FiO2 = 0.3). Haemodynamic effects in favour of He-O2 were especially seen in cardiac output in arising PEEP. It was the result of a reduced intrathoracic pressure when administering He-O2 mixtures for controlled respiration. These results must be seen in combination with the advantages of the ventilatory effects.

[Experimental studies with a new Giessen model high frequency jet ventilator].

In some critically ill patients respiratory can be maintained by high frequency jet ventilation. Gas exchange and transport by this method cannot be explained exactly up to date. Therefore it is impossible to compare this method with classical IPPV. Statistics and nomograms must be prepared for common clinical use.

[Respiration of multi-injured patients with He-O2 and N2-O2 mixtures. I. Ventilatory effects and pulmonary gas exchange].

Polytraumatic patients (n = 19), requiring for ventilatory support [8, 23, 24], were alternatively normoventilated (PaCO2 approximately equal to 40 mm Hg) with either He-O2 or N2-O2 (FIO2 = 0,3) using positive endexspiratory pressures of 0, 5, 10 and 15 cm H2O. The results demonstrated that the tidal volume decreased by 17% during the ventilation with He-O2 as compared with N2-O2. At the same time the inspiratory resistance and the inspiratory peak-pressure decreased by 20%. These results can be explained by the physical properties of helium, since helium guarantees a laminar flow during respiration in contrast to N2 even in obstructive airways. In conclusion it can be said that polytrauma patients have a inhomogeneous distribution of ventilation starting at the day of accident, that leads to a rise in deadspace ventilation. Because of having lower respiration pressures by using He-O2 mixtures, pulmonary barotrauma could be reduced.
