Using Positive Pressure Ventilation for Preoxygenation During Panendoscopy. (PANNIV)

September 17, 2025 updated by: Centre Hospitalier Universitaire, Amiens

Non Invasive Ventilation (NIV) Versus Spontaneous Breathing for Preoxygenation During Ear, Nose, and Throat (ENT) Panendoscopy. A Controlled, Prospective, Randomized Study.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: positive pressure ventilation
Positive Pressure Ventilation with a 4 cmH2O inhale pressure, a positive end-expiratory pressure of 4 cm H2O, a trigger 2, an inspiratory slope of 0, an inhaled oxygen fraction of 100% administered at a 10 L / min flow.
Device: positive pressure ventilation
Positive Pressure Ventilation with a 4 cmH2O inhale pressure, a positive end-expiratory pressure of 4 cm H2O, a trigger 2, an inspiratory slope of 0, an inhaled oxygen fraction of 100% administered at a 10 L / min flow.
Other Names:
  • non invasive ventilation (NIV)
Active Comparator: Oxygenation with simple breathing mask
spontaneously breathing preoxygenation with adapted face mask, to restrict leakage, at 10L/min oxygen, with inhaled fraction of 100% and a 2 L balloon volume.
Procedure: Oxygenation with simple breathing mask
Spontaneously breathing preoxygenation with adapted face mask, to restrict leakage, at 10L/min oxygen, with inhaled fraction of 100% and a 2 L balloon volume.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
non hypoxemic apnea time
Time Frame: up to 5 minutes after stopping oxygenation

up to 5 minutes after stopping oxygenation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: up 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
up to 15 minutes after stopping oxygenation
preoxygenation time
Time Frame: up to 10 min after the start of oxygenation
time to reach expired oxygen fraction to 90%
up to 10 min after the start of oxygenation
