• Measure and apply an adjustable cervical collar.
Patient Factors & Considerations
  • All relevant infection control methods to be utilised.
  • One person immobilises the head and neck in neutral position.
  • Assistant prepares cervical collar from a sealed package according to the size of the patient (adult or child).

  • Measure the collar size by holding your open hand on the patient’s shoulder.
  • Record how many fingers in height to the chin and transfer the measurement to the front of the collar[3].
  • Adjust lock tabs at top of collar to the transferred measurement and secure the collar in place by depressing lock tabs.
  • Maintain neutral neck/head alignment.
  • Slip the back section under the neck slightly and align the chin section with the chin of the patient[4].
  • Secure the sections together by keeping one hand on the chin brace and attach the velcro strip securely, ensuring no movement of the head/neck[6].
  • Ensure it is a snug but comfortable fit and ask the patient to stick out his/her tongue to ensure the mouth can still be opened and the chin brace is not too tight and limiting mouth movement if the patient needs to vomit.
  • Ensure the collar is located centrally on the patient with the chest support section in the center of the sternum and the neck not pushed out of neutral alignment.
  • The application of a collar alone does not protect the spine.
  • Maintain manual cervical spine immobilisation until head-blocks/spider straps are in situ.
