What information you do or don't include will depend on what the rest of your PCR looks like. For example, I'm required to input meds / history / allergies elsewhere in the PCR, so I don't clutter my narratives with that info. I used to write all that stuff about securing straps, raising rails, etc, but recently decided "whatever, it'll probably be fine...". As far as I'm concerned those things should just go without saying.
My reports follow a kind of modified SOAP method. I do a paragraph for subjective-ish, paragraph for objective-ish, and then treatment/transport. 95% of them go like this:
Paramedic 37 dispatched to above address, single family home, for "the unknown medical". On arrival, contacted 90yo female. Patient states that she awoke this morning at 4:30am with chest pain etc etc. Patient rates pain at 8/10, "heavy" in nature, radiates down left arm and to jaw. Patient states has had MI in the past and it felt similar to this. Put all the "subjective" things here, what the patient tells you, when was the last known normal if it's a stroke. If it's an MVA I put "airbags deployed, patient states was wearing seatbelt" etc.
Patient is alert and oriented to person and events, but not to place/time (husbands states this is baseline, patient has hx of dementia). Skin cool pale diaphoretic, pupils ERRL, neurologically intact. Lung sounds: coarse rales noted bilaterally. 12 lead EKG shows whatever. If it's a trauma, I put relevant findings here. Next I put any abnormal vital signs BP 80/50, HR 120, SpO2 70%. If they were fine I just write "hemodynamically stable".
Administered O2 at 15Lpm via NRB (SpO2 improves 70->80). Administered other things (effect?). Transported to Jimbob Hospital ED: STEMI ALERT called. On arrival, report given and care transferred to facility MD and RN. P37 clear.
