All patients with RDS had received surfactant before HFV. In Hamburg HFV was combined with IMV in most cases whereas in Toulouse HFV was always used on its own.

Appendix Case reports The high-frequency treatment soon relaxed the critical ventilatory situation in 48 out of 61 patients HFV, but failed in 13 patients (figure 12.7). After the onset of HFV the responders in all weight categories showed rapid improvement in blood gases, lung mechanics and ventilation parameters (figures 12.8 to 12.11). The elimination of the initial hypercapnia was most distinct with the small patients (figure 12.9). These partly dramatic changes require quick adaptation of ventilatory settings. Especially the increase in com pliance (figure 12.11) can promote overinflation. Failure of HFV was assumed when neither pCO 2 nor oxygenation index improved by at least 20% within 24 hours. With 2 out of 13 non-responders a contraindication (obstruction) was present.
