Title: A Randomized Controlled Trial of Nasal Intermittent Positive Pressure Ventilation Versus Nasal Continuous Positive Pressure as a Primary Mode for Respiratory Distress Syndrome in Preterm Infants
Brief Summary: The purpose of this study is to evaluate the hypothesis that nasal intermittent positive pressure(NIPP), used as a primary mode of ventilation in preterm infants with RDS, will decrease the need for conventional endotracheal ventilation when compared to nasal continuous positive airway pressure.(NCPAP)


Options:
A: Inclusion Criteria:

* preterm infants with RDS
* assigned to non invasive ventilation

Exclusion Criteria:

* preterm on endotracheal ventilation
* severe congenital pulmonary or cardiovascular malformation
B: Inclusion Criteria:

* All inborn VLBW infants (birthweight less than 1500 g and Gestational Age \< 32 wks) with signs of RDS, spontaneously breathing and only supported by N-CPAP, will be randomized within the first 2 hours of life to receive two different Non Invasive Ventilation (NIV) strategies.

Exclusion Criteria:

* Apneic or severely depressed newborns requiring invasive ventilation, within two hours from birth
* Newborns with genetic disease and/or with major congenital malformations
* Newborns for whom it was not obtained informed consent within two hours from birth
C: Inclusion Criteria:

1. Gestational age between 24 to 34 and 6/7 weeks assessed by the obstetrical team from dating of last menstural period or ultrasound and weight \>1000 g for the initial treatment of RDS or \<35 weeks post extubation or for apnea of prematurity
2. Infants with RDS who will need NRS as initial therapy or after extubation and for apnea of prematurity, 3. written informed consent.

Exclusion Criteria:

1. Significant morbidity apart from RDS including: cardiac disease (not including patent ductus arteriosus \[PDA\]), congenital malformation, or if they had cardiovascular or respiratory instability because of sepsis, anemia or severe intraventricular hemorrhage (IVH),
2. Parents refuse consent.
3. Unavailability of suitable ventilator.
D: Inclusion Criteria:

1. Newborn infants with birth weight \>500 gm.
2. Gestational age \>24 completed weeks.
3. Intention to manage the infant with non-invasive respiratory support (i.e. no endotracheal tube), where either: 1) the infant is within the first 7 days of life and has never been intubated or has received less than 24 hours of total cumulative intubated respiratory support; 2)the infant is within the first 28 days of life, has been managed with intubated respiratory support for 24 hours or more and is a candidate for extubation followed by non-invasive respiratory support.
4. No known lethal congenital anomaly or genetic syndromes.
5. Signed parental informed consent.

Exclusion Criteria:

1. Considered non-viable by clinician (decision not to administer effective therapies)
2. Life-threatening congenital abnormalities including congenital heart disease (excluding patent ductus arteriosis)
3. Infants known to require surgical treatment
4. Abnormalities of the upper and lower airways
5. Neuromuscular disorders
6. Infants who are \>28 days old and continue to require mechanical ventilation with an endotracheal tube
