Outcomes
Primary outcome [1] 67 0
The primary outcome will be transfer or treatment failure, as determined by the following criteria:
1. HeadBoxOxygen (HBO) only. HBO will be considered to have failed if =60% oxygen is required to maintain a saturation of =94%, and if this requirement persists for more than one hour. (75% of the participating paediatricians would definitely transfer an infant requiring > 60% oxygen.).
2. CPAP only. CPAP will be considered to have failed if =50% oxygen is required to maintain a saturation of =94%, and if this requirement persists for more than one hour. As agreed with representatives of NICUs that use CPAP as frontline treatment, and in keeping with the principle that babies in CPAP who are in the same amount of oxygen as babies in a headbox are more unwell.
3. Both groups. The persistence of a CO2 level of > 60 on two successive gasses at least 1 hour apart. (75% of the participating paediatricians would definitely transfer an infant with a CO2 of > 60%).
4. Both groups. The persistence of a pH level of < 7.25 on two successive gasses at least 1 hour apart. (75% of the participating paediatricians would definitely transfer an infant with a pH level of < 7.25).
5. Both groups. Transfer may be arranged prior to meeting these criteria for any baby if so decided through consultation between the support hospital and the attending paediatrician. The justification for doing so will be clearly documented.
Timepoint [1] 67 0
Secondary outcome [1] 117 0
1. Length of time needing oxygen. The duration of respiratory support in air (i.e., without supplementary oxygen) will also be measured.
Timepoint [1] 117 0
Length of time in oxygen will be measured in hours. This will commence from the moment of treatment commencement post-randomisation. If oxygen is recommenced during the initial stay, or if an infant is up-transferred to a NICU, this time will be added.
Secondary outcome [2] 118 0
2. Length of stay. Length of stay to discharge home will be calculated for all babies. This will include up-transfers and any down-transfers until the infant is discharged home.
Timepoint [2] 118 0
Secondary outcome [3] 119 0
3. Parental stress. A questionnaire used to identify levels of stress.
Timepoint [3] 119 0
Secondary outcome [4] 120 0
4. Pneumothorax. All pneumothoraxes will be identified whether requiring a chest drain or not. The final diagnosis of a pneumothorax will be determined by radiologist.
Timepoint [4] 120 0
Secondary outcome [5] 121 0
5. Morbidity and mortality data will be collected on all babies. The following indicators will be used as a measure of morbidity: 1. Requirement of oxygen at 28 days of age. 2. Mortality 3. Intraventricular haemorrhage. Head ultra sound will be obtained on babies where clinically indicated by the paediatrician. Any other side effects, such as ulceration of the nares, will be recorded but not included as part of this outcome.
Timepoint [5] 121 0
Secondary outcome [6] 122 0
6. Nurse workload will be measured for all babies whether randomised to HBO or CPAP.
Timepoint [6] 122 0

Eligibility
Key inclusion criteria
1. dagnosed with respiratory distress. Defined as al least one of the following: recession, grunt, nasal flare, or tachypnoea (respiratory rate >60/minute)2. Who require >30% oxygen to maintain SaO2 or> or = 94% over a period of >30minutes.3. Babies aged less than 24 hours
Minimum age
Not stated
Maximum age
31 Weeks
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Infants < 31wks gestation. 2. Infants <1200 grams. Corresponds to the 10th percentile for 31 weeks gestation. 3. Apgar score = 3 at 5minutes of age. Used as an arbitrary and de-facto indicator of possible perinatal asphyxia.4. Cardiac cause of respiratory distress. 5. Any infant who is perceived by their paediatrician to need NICU care. This “out clause” will provide an added safety mechanism and will cover infants with, for example, congenital anomalies. Potential implications for generalisability will be assessed by recording non-identifying details of all infants excluded for this reason, along with the reason for transfer.
