4. Preparing for the Critical Airway-not just the Difficult Airway-in the PICU “Although technical difficulty is the most feared and studied aspect of airway management, it is not the only aspect impacting the progression of events. The outcome of the critical care airway management is the result of many variables not included in difficult airway management algorithms….” Matioc, Adrian A. MD; Arndt, George MD; Jofee, Aaron MD The critical airway: The difficult airway in the adult critical care. Critical Care Medicine. 37(3):1175-1176, March 2009.

5. Preparing for the Critical Airway-not just the Difficult Airway-in the PICU • “Airway management in the intensive care unit is not a single provider technical event. The critical airway (CA) concept can be used to address organizational needs for airway management in the intensive care unit. CA management starts with the design of the patient's bed, the workplace (intensive care unit room), and the airway device such that it will allow an ergonomic approach to the patient's airway in minimal time. It also assumes training of the “helping” staff and continuous effort from the airway provider to improve clinical and technical skills.” Matioc, A; Arndt, G; and Jofee, A: The critical airway: The difficult airway in the adult critical care.[Letter]Critical Care Medicine. 37(3):1175-1176, March 2009.

6. Preparing for the Critical Airway-not just the Difficult Airway-in the PICU • The difficult airway has been defined as “the clinical situation in which a conventionally trained anesthetist experiences difficulty with mask ventilation of the upper airway, tracheal intubation, or both” • Yet all patients in the Pediatric ICU should initially be viewed as having a potentially “critical” airway • Making the critical care environment as conducive to difficult airway management as the operating room requires planning and teamwork.

7. Increased oxygen consumption in the pediatric patient: less reserve time to manage the airway
