Yesterday - I was called to the floor for a emergent intubation on a patient in acute respiratory on BiPAP - ABGs showed severe respiratory acidosis with PaCo2 107. The Primary was asking to intubate since he didnt get to do it often and wanted to know about using Sux. Visually, Patient had a MP 3, TMD of 2, thick neck, full set of teeth, in a supine position..chin was below the level of his chest...

What are your concerns and how would you proceed and what would you tell the MD?
