It should be noted that this information is intended as a guideline only, and the size of the interface must always be selected according to the individual baby’s anatomy. For example, a baby that has been intubated before nCPAP may have larger nostrils and therefore require a much larger prong than would be expected. While this table may be used as a starting point for selecting the most suitable size, it cannot be guaranteed that a particular size will always fit a patient in the recommended weight range.
