We have read with interest the article " Methods of weaning preterm
babies <30 weeks gestation off CPAP: a multicentre randomised
controlled trial", which has shown that weaning directly from CPAP to room
air or crib oxygen was successful rather than to nasal prong and ON/ OFF
method of CPAP.
Surprisingly, the authors were silent on few issues like
1. The CPAP pressure at weaning (whether it was 4 or 5 or 6 cm of H2O).
2. The flow used to generate or maintain CPAP pressure.
3. The type of CPAP generator and the interface used.
Lack of uniformity in the CPAP pressure at weaning, the air- oxygen
flow required to generate the pressure, the pressure generator and the
interface used, all would have effect on the primary and the secondary
outcomes evaluated by the authors.
Sir,
