Summary
Over 3000 newly born infants require mechanical ventilation in Australia every year. The majority are very premature infants. About 30% of ventilated infants develop serious ventilator induced lung injury. Minimising such lung injury with improved techniques of ventilation which can protect the lung from injury will reduce the considerable short and long term health burden of this population.
Optimising bubble continuous positive airway pressure (CPAP) for preterm infants. Synchrotron imaging will be used to see how the lungs of newborns are aerated and move when they are supported by continuous positive airway pressure (CPAP) breathing support. This project will provide fundamental biological information that will contribute to refinement of devices to support breathing in babies.
Respiratory failure at birth is a major cause of death and disease in newborn infants. At birth the airways must be cleared of liquid to allow the inhalation of air, but, little is known about the process of lung aeration, because it has not been possible to observe or measure it. We have developed imaging and analytical techniques to observed and measure lung aeration. We will determine ventilation procedures that promote uniform lung aeration and minimise lung injury in ventilated infants.
