NCT06947902

Brief Summary

The purpose of this study is to investigate which flow rate (higher versus lower) is most effective at increasing apneic time and preventing greater than 5% drop in desaturation, as well as assessing transcutaneous carbon dioxide (CO2) levels during airway procedures in children

Outcome Measures

Primary Outcomes (1)

  • Number of participants that show an incidence of oxygen desaturation >5 %

    from start of procedure to end of procedure (about 1 hour)

Secondary Outcomes (5)

  • Apnea time measured in seconds or minutes

    from start of procedure to end of procedure (about 1 hour)

  • Number of Participants With Surgical Interruptions Due to Desaturation

    from start of procedure to end of procedure (about 1 hour)

  • Oxygen nadir level

    from start of procedure to end of procedure (about 1 hour)

  • Transcutaneous CO2 measurements throughout procedure

    from start of procedure to end of procedure (about 1 hour)

  • Adverse events related to device itself (nasal pain, skin irritation)

    from baseline to end of study (1 month after baseline)
