EMT- Scene Safety and Scene Size-Up

When doing a scene size up, when should you call for help and what are three possible reasons you will need additional help?  What are some ways to determine the mechanism of injury and what type of injuries will there possibly be to take care of?  Also respond to 2 other students posts

An EMT should call for help when doing a scene size up if he/she thinks they will need additional resources like an ALS unit for more serious calls or a medical emergency concerning more than one patient. MOI and NOI is the information given to the EMT concerning the patient which gives the EMT a heads up as to what they will be expecting so that they can prepare. Some ways they will prepare include determining whether or not they will need to call for additional resources/back-up or whether or not to bring a backboard for C-Spine precautions. Some possible reasons the EMT will need additional help would include a multiple casualty incident, medical and trauma calls, if the scene is unsafe due to animals, gas leakage, fire, outraged family members, and just anything that could be hazardous/unsafe to the EMS crew,  (the scene should be safe anyway, but in the case that it isn’t, then you would need to call for scene safety/police), and/or in the case the patient is stuck in machinery and you’d need another professions with expertise in that field of area to help lift, move, or detach that industrial machinery such as a firefighter. Some ways to determine the mechanism of injury (MOI) include being given the information by the dispatcher before you arrive on scene, observing/analyzing the scene while driving/pulling up in the ambulance, and just in your overall scene size up. Some types of injuries that might be there to take care of include a patient in cardiac distress complaining of chest pain (put ALS on standby), patient with their hand stuck in a machine (need for firefighters), anxiety calls, shortness of breath patients, lacerations, burns, cuts, etc. There maybe cases when the EMT may need to call for backup once actually on scene with the patient, but the point of scene size up and MOI/NOI is to prepare so that the patient is in the best care with all the correct staff and resources to help them.
