- is a flexible device filled with small beads that conform to the patient's body shape when air is removed, providing full-body immobilization
- Vacuum mattress is particularly useful for patients with suspected spinal injuries who are found in awkward positions or have other complicating factors (pregnancy, obesity)
- Once the patient is positioned on the vacuum mattress, air is removed using a pump, causing the mattress to harden and maintain the patient's position for safe transport
Spinal Immobilization Techniques
Moving Patients with Suspected Spinal Injuries
- is used to move a patient with a suspected spinal injury onto a backboard or vacuum mattress while maintaining spinal alignment
- Log roll involves multiple rescuers working together to roll the patient onto their side as a single unit, allowing the backboard to be placed behind them before rolling them back onto it
- Proper log roll technique requires clear communication and coordination among the rescuers to ensure the patient's spine remains in a neutral position throughout the process
Clearing the Cervical Spine
- are used to assess whether a patient requires full spinal immobilization based on specific criteria and physical examination
- Protocols typically involve assessing the patient's level of consciousness, , presence of pain or tenderness in the spine, and any
- If the patient meets all criteria for spinal clearance, the cervical collar may be removed and full immobilization may not be necessary, allowing for more efficient patient assessment and transport
