Standard Operating Procedure: Emergency Medical Services (EMS) Ambulance Operations

This Standard Operating Procedure (SOP) outlines the mandatory protocols for ambulance personnel to ensure the highest standards of patient care, operational readiness, and crew safety. Compliance with these procedures is essential for maintaining life-saving capabilities and mitigating risks during emergency response, transit, and patient hand-off. All personnel must adhere to local medical protocols and legal requirements.

1. Pre-Shift Vehicle and Equipment Readiness

• Safety Inspection: Conduct a perimeter walk-around of the ambulance, checking tire pressure, fluid levels (oil, coolant, brake fluid), and fuel level (must be above 3/4).
• Interior Audit: Verify the functionality of all onboard systems, including climate control, siren, emergency lighting, and radio communication equipment.
• Medical Inventory: Check expiration dates and stock levels of all essential life-support supplies, including oxygen tanks (minimum 1,500 PSI), cardiac monitors, suction units, and advanced airway kits.
• Documentation: Ensure all Electronic Patient Care Report (ePCR) devices are charged and connected to the server.

2. Emergency Response and Dispatch Protocols

• Acknowledge Dispatch: Confirm receipt of the call via mobile data terminal (MDT) or radio with the correct address and nature of the call.
• Safe Driving Practices: Operate the vehicle using "Due Regard." Utilize sirens and lights only when legally authorized and necessary for safety; obey all traffic signals when safe to do so.
• Scene Assessment: Upon arrival, perform a 360-degree survey of the scene. Identify potential hazards (traffic, chemical spills, hostile individuals) and stage the vehicle safely.
• BSI/PPE: Apply Body Substance Isolation (BSI) and Personal Protective Equipment (PPE) immediately upon exiting the vehicle.

3. Patient Assessment and Care

• Primary Assessment: Execute the ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure). Stabilize life-threatening conditions immediately.
• Vitals Acquisition: Obtain baseline blood pressure, pulse, O2 saturation, and respiratory rate within the first 5 minutes of contact.
• Patient History: Utilize the SAMPLE (Signs/Symptoms, Allergies, Medications, Past History, Last Oral Intake, Events) mnemonic to gather patient data.
• Treatment Protocols: Administer interventions strictly according to the Standing Orders provided by the Medical Director.

4. Transport and Patient Hand-off

• Secure Patient: Ensure the patient is properly strapped to the stretcher and the stretcher is locked into the ambulance track system.
• Continuous Monitoring: Re-assess vitals every 5–15 minutes during transport depending on patient acuity.
• Radio Report: Provide a concise "I-MIST" (Identification, Mechanism/Medical, Injuries, Signs/Symptoms, Treatment) report to the receiving facility while en route.
• Formal Hand-off: Transfer care to an equivalent or higher-level provider. Obtain a signature or verbal confirmation of the transfer of care before leaving the facility.

5. Post-Call Decontamination and Restocking

• Sanitization: Clean all surfaces, stretchers, and touchpoints with hospital-grade disinfectant to prevent cross-contamination.
• Restock: Replace all used supplies immediately upon returning to the station or at the hospital supply bay.
• Documentation Completion: Finalize the ePCR and upload to the database within 60 minutes of call completion.

Pro Tips & Pitfalls

• Pro Tip: Always carry a portable "jump bag" to the patient's side. Never rely on the stretcher as your only source of equipment.
• Pro Tip: Maintain a "Situational Awareness" mindset. If the scene feels unsafe at any point, retreat to the ambulance and request law enforcement backup.
• Pitfall: Over-reliance on technology. Ensure you can perform manual vitals (manual BP cuff, radial pulse) if the electronic monitor fails.
• Pitfall: Failing to verify patient identity. Always confirm the patient’s name and DOB against ID or ask family members if the patient is unconscious.

Frequently Asked Questions (FAQ)

Q: What should I do if my equipment malfunctions mid-call? A: Immediately switch to manual backups (e.g., manual BVM for ventilation, manual BP cuff). Document the equipment failure in the ePCR and report it to your supervisor immediately upon shift completion.

Q: How do I handle a patient who refuses medical care? A: Ensure the patient is oriented to person, place, time, and event. Explain the risks of refusing care clearly. Have the patient sign a Refusal of Service (ROS) form in the presence of a witness or law enforcement officer, if necessary.

Q: When is it appropriate to bypass the closest hospital? A: You may bypass the closest facility only if the patient meets specific trauma or cardiac center destination protocols as defined by local medical authority or if the closest facility is unable to provide the necessary level of care. Always confirm with medical control before deviating from standard routing.
