Q

Lateral C-spine trauma

A

Always perform this projection 1st before any other projection
-72” SID
10 x 12” IR= placed in an IR Holder that sits atop of the pt. shoulder
CR: horizontal & perpendicular : enters C4
Respiration: Take a deep breath in, out and hold
( try to relax shoulders)
-If T1 is not seen then a swimmers is needed
