b. Line 2: Radio Frequency, Call Sign, and Suffix. Your radio frequency, call
signal, and suffix of signal operation instructions can be obtained from the Signal
Operating Instruction (SOI) or from the Automated Net Control Device (ANCD) or from
the radio supervisor. This information is needed so the evacuation vehicle crew can
contact the requesting unit while en route to obtain additional information (for example,
marking devices).
c. Line 3: Number of Casualties by Precedence. Based upon the actual
evaluation of the casualties, determine how many are urgent, how many are urgent
surgical, how many are priority, how many are routine, and how many are convenient.
This information is used by the unit controlling evacuation to prioritize missions when
more than one request is received. Definitions of these categories are given below.
(1) Urgent. Emergency case that should be evacuated as soon as possible
and within a maximum of 2 hours in order to save live, limb, or eyesight.
(2) Urgent Surgical. Emergency case that should be evacuated within 2
hours to the nearest surgical unit.
(3) Priority. Sick or wounded person requiring prompt medical care and
who should be evacuated within 4 hours or the casualty's medical condition could
deteriorate to such a degree that he could become an urgent precedence.
(4) Routine. Sick or wounded person requiring evacuation, but whose
condition is not expected to deteriorate significantly. The casualty should be evacuated
within 24 hours.
(5) Convenient. Person who is being medically evacuated for medical
convenience rather than necessity.
d. Line 4: Special Equipment Required. Based upon actual evaluation of the
casualties, determine what special equipment, if any, will need to be placed aboard the
ambulance before it begins the mission. The most common items for an air ambulance
are hoist, Stokes litter, and forest penetrator. Another common special equipment
requirement is a ventilator. This information is required so the equipment can be placed
on board the evacuation vehicle before it leaves the medical treatment facility.
e. Line 5: Number of Casualties by Type. Based upon actual evaluation of
the casualties, determine the number of casualties that will evacuated on a litter and the
number of casualties that are able to sit (ambulatory). This information is needed to
properly configure the vehicle to transport the casualties requiring evacuation.
