Experimental studies and clinical applications of a new respirator (Electronically Controlled Respirator, E. C. R.) for new borns and infants were reported.<br>Using Ayre's T-tube methode, respiration was controlled by a solenoid valve, which was regulated by an electronic controller. Respiratory pattern showed slow elevation of intratracheal pressure during inspiration and rapid decrease of intratracheal pressure during expiration. Fine control of ventilating volume, time ratio of inspiration and expiration and FI O2 were easily obtained. Assisted respiration and intermittent mandatory ventilation were also easily obtained using electromagnetic sensors applied on the chest or abdominal wall with minimal delay. Continuous monitoring of respiratory pattern and intratracheal pressure were obtained.<br>Clinical applications of E. C. R. was done since April 1970, mainely for the postoperative care of the patients with congenital heart disease who were less than twelve months of age and associated with severe resoiratory distress syndrome. Characters of E. C. R. stated above showed many advantages in respiratory care of severely ill newborns and infants and weaning from respirator was easier comparing to other respirators.
