The importance of the preterm infant's inspiratory time in determining the optimum inflation time during mechanical ventilation was investigated. The optimum inflation time was defined as that which was most commonly associated with synchronous respiration and maximum minute volume. Twelve preterm infants were studied on 14 occasions. ⋯ Synchrony was most commonly provoked and minute volume greatest at the shortest inflation time (P less than 0.01). We conclude fast ventilator rates are most efficacious for preterm neonates. As previously shown, this rate can be estimated by examining the standard reference range of rates in relation to gestational age.
