Abstract:
The Neonatal Oxygenation Prospective Meta-analysis combined the individual participant data of 4965 extremely preterm infants. They had been randomly assigned in 5 trials to arterial oxygen saturations of 85%-89% or 91%-95% using modified oximeters to mask the treatment allocation. The primary outcome of death or disability did not differ significantly between the groups. Assignment to the higher target range reduced the risks of death and severe necrotizing enterocolitis but increased the risk of treated retinopathy. Trade-offs between the benefits and risks of higher or lower saturation targets should be informed by the local patient risks and institutional rates for outcomes that may be affected by a policy change. Features of the oximeter masking algorithm introduced unanticipated artifacts into the saturation display that are not seen in routine care. NeOProM provides little guidance on where to set the oximeter alarms and how to respond to them.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
