Once in the ambulance, the patient gets loaded onto the stretcher (which is fixed and cannot be moved in any way). On the left side, you can see dressings, plasters, towels and oxygen masks that can be quickly obtained in dire necessity - on the right side (not included in the photo), the paramedic can access the defibrillator. Throughout the whole trip, the paramedic sits to the right of the patient (from the photo's angle), and should the vehicle come to an abrupt stop, the net you see in the back has the purpose of catching the flying paramedic. The equipment on the left can easily be accessed by the paramedic on the right, as it is only an arm's distance.
In case of a cardiac arrest, the paramedic sitting in the back has to quickly inform the driving paramedic to fully stop the ambulance (turning off the engine completely), and to assist in the reanimation using the defibrillator or other necessary tools. The reason why the ambulance has to be fully stopped is, among others, for the defibrillator to have a correct pulse reading of the patient's heartbeat. Once the patient is successfully reanimated, the driver can resume the hasty trip to the hospital. Lastly, the ambulance will also need to be fully stopped in case of a trauma, which can lead to puking, in which case the paramedics have to team up and turn the patient over to avoid being choked by their own regurgitation.
In the next and final picture, we'll be discussing in detail about the equipment used for on-location situations (defibrillator, oxygen tank and first aid bag). Stay tuned!
