      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Participants will be randomly assigned to two groups of intervention and control with 10 members using block randomization with block sizes of 2.
Randomized permutation blocks (block 2). 
Excel software rand function was used for randomization, Blinding description: The participants are infants and it will be impossible for them to explain the method, treatment groups, and how to randomize; Therefore, participants will not be aware of the type of intervention received and are blinded.</study_design>

      <i_freetext>Intervention 1: First intervention group: Nasal Continuous Positive Airway Pressure group; These infants underwent non-invasive ventilation Continuous Positive Airway Pressure using Bi nasal prong, Bubble Continuous Positive Airway Pressure, hot and humid airflow, and blender. Continuous Positive Airway Pressure was started with 5 cmH2O to keep the Saturation between 90 to 94 percent. Intervention 2: Second Intervention group: Nasal high-frequency oscillation group, These infants underwent non-invasive mechanical ventilation using CNO devices for Medin company and  Bi nasal prong and using oscillation and periodic opening and closing of the air outlet valve. Ventilation started by using CPAP with 5 cmH2O, frequency of 10 Hz, and oscillation that started with 5. At the beginning of ventilation, visible vibration of the upper chest was noted. It was started to keep the Saturation between 90 to 94 percent.</i_freetext>
