Modification of the standard negative-pressure respirator, which easily permits application of intermittent negative-pressure ventilation to the infant of less than 1,000 gm, has been described. Previously encountered problems of fixation of the infant, of maintenance of oxygen concentrations, and of inability to obtain chest films of the infant while in the device have been overcome.
