Continuous negative airway pressure “CNAP”: Novel nasal foreign body removal

Joyce Z. Teng, Arthur Y. Teng, Colin E. Sullivan


We report on a novel and innovative method used to extricate nasal foreign bodies in infants and young children– a common presentation in pediatric emergency care that can at times have potentially serious consequences. In the case of a three-year-old girl, ‘continuous negative airway pressure (CNAP)’ using a continuous positive airway pressure (CPAP) mask and a domestic vacuum cleaner, a nasal foreign body was removed quickly and effectively in a simple and painless procedure. While more cases are needed to confirm safety and efficacy, the principles underlying this technique could have great potential for future clinical use due to its simplicity and accessibility, particularly when compared to other techniques currently used in the home and in the emergency department.
