Sizing a one-piece hard collar

    • Measure the distance from the top of the patient's shoulder to the angle of the jaw with your hand (image 1)
    • On the collar, measure from the bottom of the rigid plastic to the "measuring post". This should correspond to the above measurement (image 2)
    • Check that the collar fits correctly
      • The neck should not be overextended
      • The mouth should not be able to be fully opened (image 3)
