Outcome Measures

Primary Outcomes (1)

  • Apnea time

    Time required for pulse oximetry to drop to 92% after start of apnea

    Elapsed time starting from discontinuation of oxygen to the time point that pulse oximetry first reaches 92% (not to exceed 520 seconds)

Secondary Outcomes (7)

  • End-tidal carbon dioxide

    Procedure (From induction of anesthesia to end of anesthesia)

  • Pulse oximetry

    Procedure (From induction of anesthesia to end of anesthesia)

  • Non-invasive blood pressure

    Procedure (From induction of anesthesia to end of anesthesia)

  • Oxygen reserve index

    Procedure (From induction of anesthesia to end of anesthesia)

  • Time to 100%

    Elapsed time starting from re-start of bag-mask ventilation at the end of apnea period to the time point that pulse oximetry first reaches 100% (estimated less than 2 minutes)

  • +2 more secondary outcomes

Study Arms (2)

High flow

EXPERIMENTAL

Apply high-flow nasal oxygenation during apnea with open mouth after adequate preoxygenation. Resume bag-mask ventilation when pulse oximetry drops to 92% or pre-set apnea time has expired.

Device: Apnea with high-flow nasal cannula

Control

ACTIVE COMPARATOR

Apply nothing during apnea with open mouth after adequate preoxygenation. Resume bag-mask ventilation when pulse oximetry drops to 92% or pre-set apnea time has expired.

Other: Apnea

Interventions

Application of oxygenation with high-flow nasal cannula with a rate of 2L/kg/min

Also known as: Airvo 2
High flow
ApneaOTHER

Apnea without any application of oxygenation

Control

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Children younger than 11 years old scheduled to undergo surgery under general anesthesia, with American Society of Anesthesiologists Physical Status 1 or 2.
