Oregon’s EMS scope of practice is set by the Oregon Medical Board under OAR 847-035-0030 and defines the maximum procedures each of the state’s four provider levels — Emergency Medical Responder, EMT, Advanced EMT, and Paramedic — may perform. That maximum is a ceiling, not a floor. Your supervising physician assigns your standing orders, and those orders can be narrower than what the statewide rule allows.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers
The practical consequence: two paramedics working for different agencies in the same county can have different authorized procedures, because their medical directors made different choices. The license tells you the outer limit. The standing orders tell you what you can actually do on a call.
Who Sets the Rules
Two agencies split the work. The Oregon Health Authority handles licensure, continuing education, and discipline through Oregon Administrative Rules Chapter 333, Division 265. The Oregon Medical Board sets the clinical scope of practice — what each level of provider may do with patients — under OAR 847-035-0030.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers
The scope rule is not a statewide protocol book. It defines the maximum functions a supervising physician may assign to you. You cannot function at all without standing orders from a Board-approved supervising physician, and that physician can restrict your scope below the statewide maximum at their discretion.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers
Emergency Medical Responder
The EMR is the entry-level certification, with an initial course of roughly 60 hours.2Oregon Health Authority. EMS Provider Education EMRs handle the most fundamental interventions. They can perform CPR and obstructed-airway care, control bleeding, splint musculoskeletal injuries, and assist with prehospital childbirth. They may administer medical oxygen and maintain airways using nasopharyngeal and oropharyngeal devices, bag-mask ventilation, and pharyngeal suctioning. They can operate an AED and, under medical director standing orders, administer unit-dose epinephrine auto-injectors for anaphylaxis.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers
Emergency Medical Technician
EMTs complete approximately 160 hours of training, including clinical and field experience.2Oregon Health Authority. EMS Provider Education EMTs can do everything an EMR can, plus additional airway management and medication administration. They may use pulse oximetry and blood glucose monitoring, administer oral glucose for hypoglycemia, and assist patients with their own prescribed medications such as nitroglycerin and inhalers. They can administer aspirin for suspected cardiac events and naloxone for opioid overdoses. EMTs also place supraglottic airway devices under their medical director’s protocols.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers
Advanced EMT
The AEMT credential requires roughly 250 hours of training on top of a current Oregon EMT license.2Oregon Health Authority. EMS Provider Education AEMTs bridge basic and advanced life support. They can establish IV and intraosseous access, perform ECG analysis, and administer medications including dextrose for hypoglycemia, nebulized bronchodilators for respiratory distress, and intramuscular or subcutaneous injections for specific conditions. AEMTs can also perform advanced airway techniques including supraglottic airway placement and may administer a limited set of IV medications under their medical director’s written protocols.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers
Paramedic
Paramedics complete an initial course lasting approximately one year and hold the broadest clinical authority in Oregon EMS.2Oregon Health Authority. EMS Provider Education They can perform endotracheal intubation, surgical cricothyrotomy, and needle decompression for tension pneumothorax. They interpret 12-lead ECGs and manage cardiac dysrhythmias with manual defibrillation, synchronized cardioversion, and transcutaneous pacing. Paramedics can prepare and administer any medication or blood product authorized by their supervising physician’s written protocols, including controlled substances like fentanyl and midazolam.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers
Oregon is among the states that allow paramedics to administer blood products in the field, but only under specific written protocols from the supervising physician. Lower-level providers have no comparable authority.
A Note on EMT-Intermediates
Oregon also recognizes an EMT-Intermediate category, a legacy designation that predates the current national framework.3Oregon Public Law. OAR 333-265-0000 Definitions Licensing for EMTs, AEMTs, and Paramedics requires current National Registry of Emergency Medical Technicians (NREMT) certification; EMRs and EMT-Intermediates are exempt from the NREMT requirement.4Oregon Health Authority. EMS Provider Licensing
Controlled Substances Sit Under the Agency, Not the Individual
An EMS agency that carries controlled substances like fentanyl and midazolam must hold a DEA registration. Federal regulations under 21 CFR 1301.20 allow an EMS agency to obtain a single registration per state rather than a separate registration for each physical location. An agency based at a registered hospital may operate under the hospital’s DEA registration without obtaining its own.5eCFR. 21 CFR Part 1301 Registration of Manufacturers, Distributors, and Dispensers of Controlled Substances
Individual paramedics do not typically hold their own DEA registrations. They administer controlled substances under the agency’s registration and the supervising physician’s protocols. The chain runs from the DEA-registered agency, through the medical director, to the individual provider’s standing orders.
How Standing Orders Actually Work
Every EMS provider in Oregon must operate under standing orders issued by a Board-approved supervising physician. No provider — not even a paramedic — may function without them.1Oregon Medical Board. OAR 847-035-0030 Scope of Practice for EMS Providers Standing orders are pre-approved procedures and treatment algorithms that let providers act without calling a physician first. When a situation falls outside those orders, providers must contact online medical direction for real-time physician guidance.
Medical directors can request their standing orders at any time, and the Oregon Medical Board or OHA can also demand to review them. A medical director who authorizes procedures beyond the statewide scope, or who fails to adequately supervise providers, faces their own professional consequences. The standing orders are also the mechanism by which medical directors restrict a provider’s scope in response to performance concerns.
Protocols vary between agencies. An OHSU review of Oregon ambulance protocols found significant variation in how agencies handle conditions like stroke, cardiac arrest, and STEMI. Stroke protocols differed in hospital bypass instructions and transport decisions, reflecting local geography, resources, and medical director preferences. There is no single statewide protocol dictating identical treatment across all agencies.
What Happens if You Exceed Your Scope
OHA lists conduct considered contrary to recognized standards of the medical profession under OAR 333-265-0083. The prohibited conduct most relevant to scope of practice includes violating standing orders without cause and documentation, using invasive procedures outside generally accepted medical standards, violating direct orders from the physician responsible for a patient’s care, and knowingly assisting another provider in exceeding their lawful scope.6Oregon Public Law. OAR 333-265-0083 Conduct or Practice Contrary to Recognized Standards
Disciplinary outcomes range from formal reprimands to license suspension or revocation, generally scaling with the seriousness of the violation and any resulting patient harm. OHA may also deny, suspend, or revoke ambulance service licenses through administrative proceedings under ORS Chapter 183.7Oregon Public Law. ORS 682.220 Denial, Suspension or Revocation of License
License discipline is not the only exposure. Performing procedures outside your authorized scope can support a malpractice claim. Courts evaluate whether you deviated from the standard of care expected at your licensure level, and damages can include medical expenses and lost income. Employers can face vicarious liability if they fail to enforce scope-of-practice compliance.
Oregon’s Good Samaritan statute (ORS 30.800) offers narrower protection than many providers assume. It shields a person rendering emergency medical assistance from liability unless the injured party proves gross negligence, but it defines that assistance as care given voluntarily, without expectation of compensation, and not in a location where emergency care is regularly available.8Oregon Public Law. ORS 30.800 Liability for Emergency Medical Assistance On-duty EMS providers working aboard a licensed ambulance are held to the professional standard of care for their level, not the gross negligence standard.
The takeaway is simple. The scope rule sets the outer boundary of what your license permits. Your medical director’s standing orders decide what you may actually do today. Working within both is the whole job.
