Comparison of Automated Oxygen Control (Closed Loop Inspired Oxygen:CLiO2™) With and Without Automated Pressure Control (Volume Guarantee®) in Preterm Ventilated Infants: A Crossover Study (CLIO-VG Study)
In Brief
A clinical study evaluating Mode of ventilation (Volume Guarantee)® and Mode of ventilation (Volume control Ventilation) for Oxygen Saturation Targetting in Preterm Ventilated Infants. Completed, enrolled 19 participants across 1 site.
Detailed Summary
This is a cross-over randomized study. Eligible participants are preterm infants born at less than 37 weeks gestation (23+0 to 36+6 weeks), who are receiving conventional mechanical ventilation through an endotracheal tube and have a need for supplemental oxygen at the time of enrolment. The planned sample size is 19 subjects completing the study with both arms (38 study periods). The objective of this crossover study is to evaluate the efficacy of the automatic oxygen control function with or without Volume Guarantee®(automatic control of ventilator pressure to deliver the set volume) mode of ventilation in keeping oxygen levels in the safe target range (90 to 95%) in ventilated preterm infants requiring oxygen therapy.

Timeline
Interventions
This is a volume-targeted mode of ventilation aimed at delivering the set tidal volume of gas by automatically adjusting the peak inspiratory pressure (PIP) on a breath-by-breath basis. Theoretically this should minimise variation in tidal volume delivery as lung compliance and the infant's condition changes. This function is achieved by an automated servo-controlled mechanism. The upper PIP limit can be set by the clinician as a safety mechanism.
Volume-Controlled ventilation (VCV) is a type of 'volume targeted' mode. It aims to target be supported the desired tidal volume by delivering a set volume (chosen by the clinician) irrespective of the underlying lung mechanics. The ventilator will generate whatever peak inspiratory pressure is necessary to deliver this volume. There is constant inspiratory flow pattern (a square flow waveform) and peak volume and inspiratory pressure delivery are achieved at the end of inspiration. During the 'control period' of 12 hours without VG, infants will using VCV A/C (assist control) as is our current clinical standard.
