Directions for Use
STEP 1
Have one rescuer manually stabilize the head and neck, gently holding the head and neck in the
neutral alignment position (Figure 1).
Note: If resistance is felt or an increase in patient discomfort is noted, follow your established
protocols for immobilization of the cervical spine in the presence of known or suspected cervical
dislocation.
STEP 2
Once the head and neck are manually stabilized, a second rescuer should apply an Ambu Perfit
ACE collar to the patient. Size the collar as determined below. Applied collar must not hyper-
extend patient’s neck.
STEP 3
Measure the distance between an imaginary plane drawn horizontally and immediately below
the patient’s chin and second horizontal plane drawn immediately on top of the patient’s shoul-
der (Figure 2).
STEP 4
Compare this distance with the distance from the collar sizing line to the lower aspect of the
plastic collar body (not the foam) (Figure 3).
STEP 5 SIZING
The Perfit ACE collar is preset to Neckless Size 3. If a larger size collar is needed, disengage the
safety locks by pulling UP on the safety buttons (Figure 4).
STEP 6
Adjust the collar to the appropriate size: the Perfit ACE provides 16 ratchet settings between the
traditional Neckless (Size 3) and Tall (Size 6).
Simply pull the collar apart until the distance between the sizing line and the plastic collar body
equals your finger measurement (Figure 5).
STEP 7
Engage the safety locks by pushing DOWN on the safety buttons (Figure 6).
STEP 8
If the Perfit ACE needs to be resized, disengage the safety locks and pull “OUT” on the ratchet
latches (“arrows”) (Figure 7, Figure 8).
The Perfit ACE may now be adjusted to smaller sizes (Figure 9).
Reset the ratchet latches by pressing “IN” on the “arrows” (Figure 10).
Now engage the safety locks by pressing DOWN on the safety buttons (Figure 11).
PRESETTING TO FOUR STANDARD ADULT POSITIONS
The collar can be sized to four standard settings (neckless - size 3, short - size 4, regular - size 5
and tall - size 6) by simply bringing the guide arrow in line with the middle of the number
marked (3, 4, 5 and 6) on four color label.
Note: The Perfit ACE collar is pressed to Neckless Size 3.
Reset ratchet latches (guide arrow) and safety buttons as described earlier.
