CPAP
Sealing the airway by holding CPAP of 20 cmH2O in the anesthesia circuit and slowly inflating the cuff until no air leak is heard with a stethoscope placed in the suprasternal notch.
Tidal volume
The ratio of the inspired to expired tidal volume will be determined using the following formula: (TVinspired - TV¬expired)/TVinspired. The peak inflating pressure (PIP) required to achieve the set TV will be noted. The air in the cuff will then be increased or decreased as needed to achieve a set delivered ratio of 0.9-1.0.
