Communications
Communications:• Interagency communications must be
available• Important to asses and update potential
resources (Fire Dept., Additional EMS units, ER.Dept, Law Enforcement)
• Communication between agencies is of the utmost importance
![Page 17: Gaining Access & Vehicle Extrication The Role of EMS During Patient Extrication or Rescue.](https://reader035.fdocuments.us/reader035/viewer/2022081506/56649da25503460f94a8eab3/html5/thumbnails/17.jpg)
Communications
Communications con’t:• Messages, whether sent via radio or in
conversation, must be clear, concise and to the point
• During major incidents members may be required to change to a different frequency on their radios so as not to hamper radio transmissions on a department’s primary channel. Secondary and tertiary channels should be established before or on arrival at the scene
• Special codes or radio language should be common between all members (e.g. 10 codes)

Removing Laminated Glass
Try pulling out rubber seal around window, remove window intact
Cut windshield with saw, axe, or specialized tool
If cutting, USE DUST MASKS ON RESCUERS AND PATIENT! Let patient and other rescuers know you are “CUTTING GLASS!”
![Page 46: Gaining Access & Vehicle Extrication The Role of EMS During Patient Extrication or Rescue.](https://reader035.fdocuments.us/reader035/viewer/2022081506/56649da25503460f94a8eab3/html5/thumbnails/46.jpg)
Removing Tempered Glass
Try rolling down side windows, try pulling rubber out around rear windows
Break window with a center punch (bottom corner) or pointed object
When possible, use farthest window Pull glass out, possibly into tarp or
sheet, then roll it up Make sure patient and rescuers know
you are “BREAKING GLASS!”, cover Pt.

Disentanglement
Always use soft and hard protection
EMS must maintain patient contact
EMS must maintain contact with rescuers
Continue re-assessing patient Treat patient accordingly, C-
collar, KED, Splints, etc.

Caring For The Patient
Safety while treating the patient is paramount. If available, a safety officer should be established along with the IC. Safety can also be another roll the IC and his crew members, leaving the IC with the overall command.
Personnel should establish direct communication link between EMS involved with Pt. care and those performing extrication.
Always communicate to ensure safety of all involved
![Page 52: Gaining Access & Vehicle Extrication The Role of EMS During Patient Extrication or Rescue.](https://reader035.fdocuments.us/reader035/viewer/2022081506/56649da25503460f94a8eab3/html5/thumbnails/52.jpg)
Caring For The Patient
Once the EMS has gained access, he or she acts as the eyes and ears. He or she must communicate with the extrication members, Pt., and additional EMS resources during extrication.
EMS also decides (and must recognize) load and go situations or stay and play situations.
![Page 53: Gaining Access & Vehicle Extrication The Role of EMS During Patient Extrication or Rescue.](https://reader035.fdocuments.us/reader035/viewer/2022081506/56649da25503460f94a8eab3/html5/thumbnails/53.jpg)
Caring For The Patient
For patient safety, here are a few tips:» Ensure the Pt’s airway and control C-spine» Assess the Pt’s breathing and pulse» Establish the Pt’s L.O.C. and re-evaluate» Scan the Pt. starting at the head» Control hemorrhage as you encounter severe
bleeding» Treat for shock» Provide emotional first aid as well as physical first aid
» Personnel should explain what is happening around the Pt.(e.g. we are going to be breaking the window across from you)
