Paul DeBartolomeo demonstrates how to use air bags to free a victim trapped under the front end of a vehicle.
[BLANK_AUDIO] [MUSIC] Hi, I'm Paul DeBartolomeo. Welcome to Training Minutes. In this month's segment we're gonna discuss a single point parallel lift. In this scenario, we have a person pinned under the front end of a vehicle. We're gonna show how we would do a single point parallel lift to free this person. Once on scene the first thing that we need to do is walk around the vehicle to do a survey. We're looking for any hazards and the possibility of another victim underneath the vehicle. Once our scene survey is done, we want to stabilize the opposite side of the vehicle, in this case the passenger side of the vehicle. The firefighters are gonna come in. Using step shocks, they're gonna stabilize this vehicle. We want to stabilize the opposite side of the vehicle so that when we lift, we don't have a negative reaction. As we life the driver's side of the vehicle, the passenger's side of the vehicle's gonna wanna dip down. By putting the step-shocks into place, we're gonna avoid that. The reason that we would do this is that our patient is pinned under the vehicle, any downward pressure could further injure that patient. So now the vehicle is stabilized, we're gonna walk around the driver's side and we're gonna set up for our parallel. Our single point parallel lift. We wanna have a point midway on this vehicle. On a four door sedan we have the B post here, between the front and the rear door. We're gonna build our lift stack right on the rocker panel, midway on the vehicle, in order to lift this vehicle up completely parallel and even. Firefighter is gonna come in with his air bags. Build up his [UNKNOWN] stack using four by fours and two by fours. [SOUND]. We never wanna put any piece of our body underneath the load. So what he's doing is he's using the 2x4 to push the cribbing into place. He's creating a solid base for his air bags. We always use stack bags. We put the bigger bag on the bottom, the smaller bag on top. The advantage of stack bags is we get added height. The additional firefighters are coming in and starting to build up their, their capture stacks. Any time we're gonna put rescuers under a load we're gonna capture that load first. We don't wanna rely on the air bags for stability. their job is to lift the load, not stabilize the load. So it's very important that we build capture stack sin this instance. The firefighter building a lift stack has utilized the pad. A plywood pad on top of the air bags this is going to distribute the surface area a little better. It's going to allow for a more even lift. Okay our capture stacks are just about completed. Our lift stack is in place. As we can the plywood pad is secure on top of the airbags and in contact with the other side of the vehicle. So as soon as we start to inflate these bags we're going to get reaction. We don't wanna waste the airbags lifting up to make contact with the under side of the vehicle. We wanna build right up to the under side of that vehicle, so that we can get the maximum out of our airbags. We're ready to lift. >> Up on red. Stop. Up on green. Stop. As we lift, the firefighters are stabilizing the load as we go along with lift an inch, we crib an inch. (Music) [NOISE] [MUSIC] [NOISE] [MUSIC] [MUSIC] Once the load is stabilized, we can continue the lift if we need added height. [MUSIC] [MUSIC] Stop. [INAUDIBLE] Stop. [MUSIC] Once we've reached our desired height, we can back the airbags down and capture the load with our cribbing. Firefighters will finalize their captured stacks so we can accomplish this. [MUSIC] [NOISE] [MUSIC] [MUSIC] Down on three. >> We'll back the airbags down just enough so the capture stacks capture our loads. [MUSIC] Down on ratchet. [MUSIC] Once the load is captured we can move around to the front of the vehicle in an attempt to extricate the victim. [MUSIC] As with any extrication, we would want to perform c spine immobilization, properly board and collar this person before moving them. I'm Paul [UNKNOWN], thanks for watching this month's segment of Training Minutes. [MUSIC]
