A Comparison of Controlled Ventilation With the V60 Non-Invasive Ventilator vs. Traditional Mask Ventilation
August 8, 2016 updated by: Kai Kuck, University of Utah
The purpose of this study is to determine whether an experienced anesthesia provider can adequately and/or easily mask ventilate an anesthetized patient with a commercial non-invasive ventilator device.

Detailed Description
The purpose of this study is to determine whether an experienced anesthesia provider can adequately and/or easily mask ventilate an anesthetized patient with a commercial non-invasive ventilator device.
The ventilator subject of this study is commonly used in the ICU and investigators aim to evaluate its usefulness in the OR.
Investigators believe that the ventilator will ventilate with consistent breath rates, adequate tidal volumes and minimal airway pressures.
The providers subjective scoring of ease or difficulty of ventilation with each device will also be recorded.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Noninvasive Ventilation
After induction of anesthesia, checking of ability to bag mask ventilating the patient, the manual bag ventilation will be replaced by a Noninvasive Ventilator, V60 (Philips)
|
The noninvasive ventilator will be set to deliver 10 breaths per minute with a pressure setting of 8 cm H2O during exhalation and 20 cm H2O during inspiration.
The inspired oxygen fraction given by the ventilator will be set at the maximum level (100% oxygen).
Oxygen will flow through the standard breathing circuit with the fresh gas flow rate set at 10 L/min and the patient will be ventilated.
The anesthesia provider will manually bag mask ventilate the patient until the anesthesiologist feels comfortable that the patient can be ventilated appropriately.
