[Artificial ventilation of prematures and new bornes with the bennett pr-2 (author's transl)].

Difficulties and complications during artificial ventilation of prematures and newbornes gave rise to investigate the pressure-flow-characteritics during artificial respiration with the flow-time-cycled respirator Bennett PR-2 in combination with thin tracheal tubes. The flow and corresponding pressures generated by the respirator under different conditions were investigated. It is suggested that a sufficient respiration is not possible with a low generator pressure and high tidal frequencies under pathological conditions as it is often practised.
