Goal Directed Numeric Coaching as a Means of Preoxygenation

Pre-oxygenation is an anesthetic technique that allows for extended apneic (suspension of breathing) time prior to attempted endotracheal intubation. A common method to achieve adequate pre-oxygenation is having a patient take four vital capacity breaths of 100% oxygen in thirty seconds. This study seeks to determine if goal directed numeric coaching can lead to more accurate vital capacities during this technique.
