The department operates 18-26 Demers Type I and Braun Type-III modular-style ambulances on any given day, each designated a four digit unit number of the pattern 23xx. For frontline ambulances, the final number matches the precinct the ambulance is assigned to. For example, an ambulance assigned to the fourth precinct would follow this model: 23x4. The third number is chosen at the discretion of headquarters and can be any single digit number, so long as an ambulance with that designation is not already in service. Spare ambulances do not follow this system. All ambulances are advanced life support ambulances and carry heart monitors, defibrillators, oxygen, trauma dressings, intubation kits, IV and IO needles and tubing, Advanced Life Support medications and other vital medical equipment. In mid 2019, NCPD deployed automated CPR devices (specifically the brand "LifeArm") to all its ambulances. These had previously been limited to supervisors vehicles only, due to the expense. However given that police medics ride solo, the dangers CPR poses to an EMS provider while an ambulance is moving, and the effectiveness of automated CPR, the county decided to use asset forfeiture funds to purchase enough additional devices so that all its ambulances could have one. As of October 2019 the deployment of these devices was reported to be complete.
