Volume delivery during high frequency oscillation.
AIM To examine the delivered volume during "high volume strategy" high frequency oscillation, used as rescue treatment in preterm infants; and to identify factors, other than frequency and oscillatory amplitude, influencing the magnitude of volume delivery. METHOD Twenty infants (median gestational age 29 weeks) were studied on 45 occasions. Two oscillator types were used (SensorMedics and SL...
متن کاملMeasurement of lung volume and optimal oxygenation during high frequency oscillation.
Twelve infants, median gestational age 27 weeks and postnatal age 1 day, were examined to determine whether oxygenation improves on transfer to high frequency oscillation (HFO). Lung volume was assessed before transfer to HFO by measuring functional residual capacity (FRC) using a helium gas dilution technique and specially designed infant circuit. On transfer to HFO, the inspired oxygen was in...
متن کاملHigh frequency oscillation.
It is more than 15 years since high frequency oscillatory ventilation (HFOV) was first described as a technique of ventilation [ 1 ]. In the intervening period it has passed through a phase of being a physiological curiosity, where it could be demonstrated that normal gas exchange could be maintained using tidal volumes much smaller than deadspace at rates much greater than what was then consid...
متن کاملOptimal mean airway pressure during high-frequency oscillation: predicted by the pressure-volume curve.
BACKGROUND A number of groups have recommended setting positive end-expiratory pressure during conventional mechanical ventilation in adults at 2 cm H2O above the lower corner pressure (P(CL)) of the inspiratory pressure-volume (P-V) curve of the respiratory system. No equivalent recommendations for the setting of the mean airway pressure (Paw) during high-frequency oscillation (HFO) exist. The...
متن کاملHaemodynamic changes during high frequency oscillation for respiratory distress syndrome.
In a crossover trial left ventricular output (LVO), cerebral blood flow velocity (CBFV), and resistance index (RI) of the anterior cerebral artery were compared using Doppler ultrasonography, in eight preterm infants with respiratory distress syndrome (RDS) during conventional mechanical ventilation and high frequency oscillation. LVO was 14% to 18% lower with high frequency oscillation. There ...
