Eligibility
Inclusion criteria
Inclusion criteria: Infants born will be included in this study if they are between 24 and 27 completed weeks gestation receiving PPV for resuscitation at birth
Exclusion criteria
Exclusion criteria: if they are found to have a congenital abnormality or condition that might have an adverse effect on breathing or ventilation, including: congenital diaphragmatic hernia, tracheo-oesophageal fistula or cyanotic heart disease.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The proportion of tidal volumes delivered during manual PPV to an infant within the target range of safe tidal ventilation. The target range of adequate tidal volume is defined as 4-8 mL/kg. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes: clinical - Rates of endotracheal intubation in the first 24 hours after birth - The need for circulatory support over first 24 hours (inotropes and fluid boluses) - Incidence of air leak (pneumothorax, pulmonary interstitial emphysema,or pneumomediastinum) in the first 72 hours, reported by a radiologist masked to the intervention. - Incidence of abnormal cranial ultrasound findings (i) all intraventricular haemorrhage, (ii) severe - ie. Papile grade III and IV intraventricular haemorrhage, (iii) periventricular leukomalacia - Duration of endotracheal (ET) ventilation (hours). - Duration of nasal CPAP (hours). - Duration of supplemental oxygen therapy (hours) - Total duration of assisted ventilation (ET, CPAP) in hours - Incidence of bronchopulmonary dysplasia (BPD) at 36 weeks corrected gestational age defined as the need for supplementary oxygen and/or any form respiratory support. The severity of BPD will be assessed as proposed by Jobe et al.34 and oxygen reduction test will be performed in case of moderate BPD as described by Walsh et al35. - Neonatal mortality - death before discharge from hospital. - Composite outcome of death or BPD Secondary outcomes: physiological and biochemical measurements 1. Oximetry data on SpO2 and heart rate in the first 10 minutes from birth will be downloaded 2. Duration of significant mask leak (defined as > 60 %) as a proportion of time face mask was used. 3. Significant airway obstruction (defined as a reduction in flow and volume ( | — |
