[Modified Wright-spirometer for babies and small children (author's transl)].
We were able to increase the sensitivity of the Wright Spirometer five fold by a slight technical modification. Respiratory volumes as low as 5 ml could be measured accurately and corresponded will with the bell spirometer. Because most respirators include a considerable compression volume during expiration, we prefer to take measurements directly at the tube. The dead space could be reduced from 34 to 20 ml and we therefore take measurements only during 30 s with infants and 20 s with premature babies and give a higher oxygen concentration during this period. The modified spirometer has been tested clinically with success. It is of great help to determine initial tidal volumes. Subsequent controls can be done easily and allow a correlation with blood gases and if necessary a change of the respiratory volume.
