Nasal intermittent positive pressure ventilation is likely to have an
increasing role in the management of acute ventilatory failure, weanin
g, and chronic ventilatory problems. Further improvements in ventilato
r and mask design will be seen. Appropriate application is likely to r
educe both mortality and admissions to intensive care, while domicilia
ry use can improve life expectancy and/or quality of life in chronic v
entilatory disorders. As with any new technique, enthusiasm should not
outweigh clear outcome information, and possible new indications shou
ld always be subject to careful assessment.
