[H.R.P.-System 2000: a new universally applicable ventilation system for single or limited multiple use with high bacteriologic-hygienical safety (author's transl)].

A new bacteriologically safe system for artificial respiration, H.R.P.-System 2000, is presented. Only two different SETS for artificial respiration of prematures, newborns and infants (P.N.J.) and adults, children and todlers (A.T.) are necessary. They can be adapted very easily on different types of respirators. Besides the tubing and expiratory valve the H.R.P.-SETS include a highly efficient electronically controlled humidifier working on the principle of gas bubbling through a heated water bath, a special tracheal tube adapter with an automatic water exhaust and flexible gas-reservoir for manual ventilation as well as C.P.A.P. or I.M.V. therapy. The H.R.P.-SETS are available as steril disposables. Resterilisation with gas on several occasions is possible. In a control study on thirty children, mainly premature infants and newborns a conventional SET, similar to the Bennett respiration system with disposable tubing and the H.R.P.-SETS are compared under the conditions of our intensive care unit. Using the criteria of serial bacteriological examinations of the tracheo-bronchial secretions and clinical criteria, H.R.P.-SETS proved superior. Artificial respiration without bacterial contamination by hospital strains for more than 10--14 days seems to be possible as a routine in newborns and children.
