Description of intervention(s) / exposure
Observations will be recorded by a person uninvolved in the clinical care of the infant and verified by stored data (except FiO2) on the oximeters. Variables are:

First 10 minutes -
1. Time of delivery of body
2. Time of cord clamping
3. FiO2, SpO2 and heart rate for every minute after cord clamping for 10 minutes
4. Type and timing of cardiorespiratory intervention
Prior to leaving the delivery room and at 24 hours of age -
1. Birth outcome (deceased/alive/transferred to nursery/well infant, no further medical care needed)
2. Type of cardiorespiratory support (if applicable)
3. Presence of cardiopulmonary pathology (if known).
Observations will cease at 24 hours because the majority (>80%) of newborn deaths will occur in the first day of life (WHO, n.d.). Cardiopulmonary pathology will be defined as 1. The need for supplemental oxygen to maintain SpO2 > 95% and/or 2. The need for mechanical ventilatory support after delivery room stabilization and/or 3. Structural anatomical lesions that interfere with oxygenation e.g. cyanotic heart disease. Infants will be excluded if there is no personnel to collect data or if equipment is unavailable.

Statistical methods / analysis
We aim to recruit 2% of total births in the participating hospitals across the study period. 10% are expected to require intervention at birth, including positive pressure ventilation with oxygen. Funding, ethics approval and practical constraints throughout the COVID-19 pandemic will impact on the feasibility of the target sample size.

Summary
Brief summary
AIR is an observational study that aims to determine if oxygen saturations (SpO2) of newborn infants 32 to 36 weeks gestation can reach recommended levels suggested by international expert guidelines.

Currently, international guidelines recommend that respiratory support for newborn infants at or above 35 weeks gestation and those between 32-34 weeks gestation be initiated with air (21% oxygen) and 21-30% oxygen, respectively. For the first 10 minutes of life, guidelines also recommend that the amount of oxygen given to the infants should be adjusted to target SpO2 of healthy, full-term infants.

This is part of multicentre study of hospitals in New South Wales Australia aiming to recruit 200 babies.
