Formerly under the jurisdiction of Committee F30 on Emergency Medical Services, this guide was withdrawn in January 2024 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

4.1 The intent of this guide is to identify characteristics that an ACSID shall possess.

4.2 It is not expected that the ACSID will be used alone to provide the entire scope of required immobilization. Clinical situations may require differing combinations of devices for adequate total spinal immobilization. An ACSID may be one of the devices.

4.3 An ACSID is intended to provide stabilization and/or support in addition to other immobilization devices in one or more of the planes of motion mentioned in 3.2.1 (see 4.2).

1.1 This guide establishes minimum standards for devices designated here as adjunct cervical spine immobilization device (ACSID); a lateral stabilizer for the head is an example of this type of device. The ACSID is designed to be used to assist in the immobilization of the cervical spine, by emergency medical services personnel.

1.2 This guide does not identify specific degrees of limitation of motion achieved by placement of an ACSID on a patient. Definitive requirements for immobilization of the spine, and, in particular, the degree of limitation associated with the use of an ACSID, have not been established in the medical literature.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
