Air or 30% oxygen at birth for moderate-to-late preterm babies (AIROPLANE)

Peart SR, Manley BJ, Cheong JLY, et al; for the AIROPLANE Trial Investigators. JAMA. 2026. doi:10.1001/jama.2026.14201. An unblinded, cluster randomised crossover trial.

AIR OR 30% O2
NO DIFFERENCE
AT BIRTH
STUDY AT A GLANCE
Clinical question
In babies born at 32-35 weeks who need breathing support at birth, does starting with 30% oxygen rather than air (21%) reduce the need for ongoing respiratory support?
Design
Unblinded, cluster randomised crossover trial. Each hospital used one starting oxygen level, then crossed over to the other halfway through recruitment.
Setting
26 Australian maternity hospitals across Victoria and NSW - tertiary and non-tertiary, metro, regional, public and private. December 2022 to September 2025.
Population
1818 babies born at 32-35 weeks with no major anomalies, who started respiratory support within 3 minutes of birth. Mean 34.1 weeks, mean birth weight 2165 g.
Intervention
Initial FiO2 0.30 vs 0.21 (air) for the first 3 minutes of delivery-room support, then titrated to target saturations.
Primary outcome
Still receiving any respiratory support (or death) when leaving the delivery room.
Consent
A waiver of informed consent - a pragmatic, minimal-risk comparison of standard practices where genuine equipoise existed.
Close to home
An Australian trial (Victoria and NSW) that deliberately included regional and non-tertiary sites.
KEY RESULTS

No difference in the primary outcome

Ongoing respiratory support on leaving the delivery room was 72.6% (30%) vs 73.3% (air). Risk difference -0.83% (95% CI -4.33 to 2.67).

Consistent across subgroups

No difference by gestation (32-33 vs 34-35 weeks) or by tertiary vs non-tertiary centre.

Less escalation with 30% (exploratory)

Babies started on 30% were less likely to receive higher-level delivery-room support (PPV, intubation or supraglottic airway, compressions or adrenaline); proportional OR 0.70 (95% CI 0.52-0.95).

Less intubation afterwards (exploratory)

Endotracheal ventilation beyond the delivery room was 6.4% vs 9.3% (RR 0.69, 95% CI 0.47-0.91).

The verdict

For 32-35 week babies, starting with air or 30% made no difference to the main outcome. The signals of less escalation with 30% are exploratory and not adjusted for multiple testing.

WHY THIS MATTERS

  • Moderate-to-late preterm babies (32-36 weeks) are about 85% of all preterm births but are barely represented in resuscitation trials
  • Guidelines are clear at the extremes (air at 35+ weeks; at least 30% below 32 weeks) but say there is insufficient evidence for 32-35 weeks
  • Practice varies widely: in one international survey 42% started with air, 35% with 30%, the rest higher
  • Too much oxygen at birth generates free radicals and can harm; too little may slow the transition
  • A large, pragmatic Australian trial gives a locally relevant answer

STRENGTHS

  • Large (1818 babies) and pragmatic, across 26 diverse Australian sites
  • Directly answers a gap the guidelines label insufficient evidence
  • Cluster crossover design: each site used both strategies, reducing between-site imbalance
  • Included regional, non-tertiary, public and private hospitals, so broadly generalisable
  • A waiver of consent captured a representative population, not only consented babies

LIMITATIONS

  • Unblinded - clinicians knew the starting oxygen and may have escalated care differently
  • The two levels are close (21% vs 30%) and only applied for the first 3 minutes; most babies in both groups had their FiO2 escalated anyway
  • The primary outcome (support on leaving the delivery room) is somewhat subjective in a low-risk population
  • No physiological data, no timing of oxygen changes, and no follow-up beyond discharge
  • The secondary-outcome signals were not adjusted for multiple testing, so they are hypothesis-generating only

Practice implications

Most babies who need help at birth in a special care nursery are moderate-to-late preterm, so this trial speaks directly to them. The headline is reassuring: for babies born at 32-35 weeks, starting delivery-room support with air (21%) or 30% oxygen made no difference to whether they still needed respiratory support on leaving the delivery room. Follow your local and ANZCOR guidance for the starting oxygen, then titrate promptly to the target saturations - that titration matters more than the exact starting point. The exploratory signals that 30% led to a little less escalation (less PPV, less intubation) are interesting but not definitive, and should not on their own change practice. Keep the basics excellent: a good mask seal and effective inflations, a pulse oximeter with saturation targets, and early escalation when a baby is not responding.

DISCUSSION QUESTIONS
1

What starting oxygen does your unit use for a 33-week baby, and why?

2

How much does the starting FiO2 matter compared with how quickly you titrate to target saturations?

3

How should we weigh an exploratory signal (less escalation with 30%) against a neutral primary outcome?

4

Would blinding have been feasible, or worthwhile, in a delivery-room oxygen trial?

Take-home message: AIROPLANE, a large pragmatic Australian trial, asked whether babies born at 32-35 weeks should start delivery-room support with air or 30% oxygen. There was no difference in the main outcome (ongoing respiratory support on leaving the delivery room; about 73% in both groups). Exploratory findings hinted at slightly less escalation with 30%, but these are not definitive. For now, use your local and ANZCOR starting oxygen and focus on prompt titration to target saturations and effective breathing support.
