RESUMEN
Continuous positive airway pressure (CPAP) is being increasingly used in children of all age ranges. The limited number of commercially available masks especially in infants and young children may complicate its use and compliance. In this report, we describe our experience with the use of the Optiflow™ (Fisher and Paykel Healthcare) Nasal Cannula attached to a regular CPAP device in the setting of chronic CPAP use. This interface consists of a nasal cannula and was originally designed for the delivery of high-flow oxygen therapy. We could show an objective improvement in breathing parameters in several children selected for CPAP mainly because of obstructive sleep apnea syndrome (OSAS). However, this interface cannot be used for bilevel non-invasive ventilation due to insufficient triggering.
