The PEAS Protocol, an Airway Ultrasound Technique.

Abstract

In the past ultrasound identification of the airway structure was rather difficult However, recent advancement of the high frequency linear type transducer allows us to visualize airway structure easily. Accordingly, now we have difficult airway society guideline 2015. resuscitation guideline 2015, and Australia and New Zealand Intensive Care Society guidelines for percutaneous dilatational tracheostomy which recommend use of ultrasound in airway management Airway ultrasound is an emerging technique for all physicians, and the author introduces perioperative evaluation of the airway via sonography, the PEAS protocol.
