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

The University of Texas Health Science Center at Houston
Houston, Texas, United States
Number of participants that show an incidence of oxygen desaturation >5 %
Time frame: from start of procedure to end of procedure (about 1 hour)
Apnea time measured in seconds or minutes
Time frame: from start of procedure to end of procedure (about 1 hour)
Number of Participants With Surgical Interruptions Due to Desaturation
Number of surgical interruptions due to desaturation defined by a pause in surgical procedures due to need to provide airway intervention to improve patient's oxygen saturation, normalized to case length. Airway interventions may include LMA, bag mask ventilation, and/or endotracheal intubations
Time frame: from start of procedure to end of procedure (about 1 hour)
Oxygen nadir level
Time frame: from start of procedure to end of procedure (about 1 hour)
Transcutaneous CO2 measurements throughout procedure
Time frame: from start of procedure to end of procedure (about 1 hour)
Adverse events related to device itself (nasal pain, skin irritation)
Time frame: from baseline to end of study (1 month after baseline)
