Comparative Study Clinical Trial Controlled Clinical TrialComparison of different rates of artificial ventilation in preterm neonates with respiratory distress syndrome.
The effectiveness of three different ventilator rates of artificial ventilation (30, 60 and 120/min) was studied in 32 preterm infants, all of whom were suffering from the Respiratory Distress Syndrome (16 were paralysed). Ventilator pressures, I:E ratio and MAP were kept constant at each rate. ⋯ Two different ventilators were used in the study and a significant change in PaCO2 (reduction) occurred only in non-paralysed infants ventilated at a rate of 120/min by Sechrist ventilators (p less than 0.05). This difference may be a direct reflection of differences in ventilator performance at fast rates.
