Apnea is categorized based on presence or absence of upper airway obstruction; 40% of the episodes are central or diaphragmatic with no evidence of obstruction, 10% are obstructive, and 50% are mixed [2]. Majority of participants in our study experienced mixed type of apnea with both central and obstructive elements. Our study did not predispose the participants to hypoxia. Firstly, it was not 20 apnea episodes per day. Apneas were recorded per 24 hours and sum of apneic spells during 4th to 7th day of therapy was depicted in the Table II (20 is total episodes). Any neonate with recurrent apneas, or apnea requiring bag and mask ventilation was considered for CPAP. Conventional mechanical ventilation was the backup option for infants who had significant apnea and bradycardia on methylxanthines and CPAP.
