Q

Explain the process of removing a helmet…

A

2 man team
1- #1 at the top of patients head, maintain manual stabilization, two hands hold helmet stable while fingers hold jaw.

4. #1 releases manual stabilization and pulls the sides of the helmet out and pulls off using a teetering motion.

27
Q

When is it required to leave the helmet in place?

A

-if helmet fits snug, with little to no movement
-not impending airway or causing breathing problems
-if removal would worsen the injury
-proper spinal immobilization can be done with a helmet
-no interference with the ability to check ABC’s

28
Q

When is it necessary to collar somebody?

A

-limited range of motion
-fall over 1 meter or 5 stairs
-axial load to the head
-MVC greater than 100KPh
-MVC with ejection or death
-MRV accident
-bike collision with immovable object
-65 years plus
-underlying spinal disease
-previous cervical spine injury

29
Q

What are the signs and symptoms of a spinal cord injury?

A
