[Liquid ventilation. 2].
The authors made two series of experiments in rabbits, using liquid ventilation. The first group was ventilated manually using RM 101 solution with an equilibration period of 30 and 60 sec., Tv = 10 ml/kg after previous administration of 30 ml/kg RM 101 at the beginning. The second group was ventilated using a specially developed liquid ventilator--part of the animals was ventilated with an equilibration interval of 30-90 sec., Tv = 10 ml/kg with administration of an initial dose od 30 ml/kg of RM 101 solution, a part of the animals in a continual manner, i.e. without an equilibration period and without administration of the initial dose of the solution. From the results it is apparent that the optimal way as regards blood gases and minimal manner of liquid ventilation. When this method was used during the 180 minutes of liquid ventilation paO2, paCO2 and pH were within the normal range. The other methods of liquid ventilation led rapidly to hypercapnia and a drop of pH as well as to serious changes in the circulation (hypertension, bradyarrhythmia).
