Using Positive Pressure Ventilation for Preoxygenation During Panendoscopy.

Not Applicable
Completed
Conditions
ENT Cancer Screening
Registration Number
NCT02167334
Lead Sponsor
Centre Hospitalier Universitaire, Amiens
Brief Summary

the aim of the study is to determine if Spontaneous Ventilation with Positive Pressure Ventilation (PPV) preoxygenation allows a longer non hypoxemic apnea time during panendoscopy compared to spontaneous breathing preoxygenation.

the hypothesis is PPV extends the residual functional capacity of lung so it provides more oxygen during apnea.

Primary Outcome Measures
NameTimeMethod
non hypoxemic apnea timeup to 5 minutes after stopping oxygenation

time the oxygen saturation is going down to 90% during apnea

Secondary Outcome Measures
NameTimeMethod
surgical laryngoscopy frequencyup to 15 minutes after stopping oxygenation

number of stopped surgical laryngoscopy because of a low oxygen saturation under 90% with necessity to ventilate the patients during apnea

preoxygenation timeup to 10 min after the start of oxygenation

time to reach expired oxygen fraction to 90%
