Experimental: CPAP 8

Upon arrival of the infant on the neonatal resuscitation trolley, start the normal standard procedures required by international protocols (e.g., drying, temperature control measures, placement of pulse-oximeter sensor to the right hand or wrist, etc.). Immediately start CPAP application with mask and T-piece: the CPAP level will be set at 8 cmH2O. Perform gentle tactile stimulation if the child is not breathing in appropriately. Place the pulse-oximeter sensor on the right hand then connect it to the oxymeter previously turned on. Assess breathing and HR for 30 seconds. Perform the next step of the flow-chart of resuscitation in the delivery room according to the Neonatal Resuscitation Program guidelines. If positive pressure ventilation (PPV) is required (in case of persistent bradycardia or apnea), maintain PEEP at 8 cm H2O and an initial PIP of 25 cm H2O. The CPAP level will be reduced to 6 cm H2O after 15 minutes of life, then the recording will be discontinued.

Active_comparator: CPAP 5

Upon arrival of the infant on the neonatal resuscitation trolley, start the normal standard procedures required by international protocols (e.g., drying, temperature control measures, placement of pulse-oximeter sensor to the right hand or wrist, etc.). Immediately start CPAP application with mask and T-piece: the CPAP level will be set at 5 cmH2O. Perform gentle tactile stimulation if the child is not breathing in appropriately. Place the pulse-oximeter sensor on the right hand then connect it to the oxymeter previously turned on. Assess breathing and HR for 30 seconds. Perform the next step of the flow-chart of resuscitation in the delivery room according to the Neonatal Resuscitation Program guidelines. If positive pressure ventilation (PPV) is required (in case of persistent bradycardia or apnea), maintain PEEP at 5 cm H2O and an initial PIP of 25 cm H2O. The CPAP level will be raised to 6 cm H2O after 15 minutes of life, then the recording will be discontinued.
