Effect of Head Rotation on Efficacy of Face Mask Ventilation in Anesthetized Obese (BMI ≥ 35) Adults

Completed · Not applicable

Conditions studied: Noninvasive Ventilation

In brief

Mask ventilation is fundamental to airway management at the start of surgical procedures requiring general anesthesia. For general anesthesia, medications are provided that affect the entire body and lead to a loss of consciousness. Medical professionals perform mask ventilation by placing a plastic mask over a subjects mouth and nose to provide enough oxygen for the placement of a breathing tube. In this study, we expect that a 45 degree rotation of the head will increase the efficiency of mask ventilation.
