2.3 Onboard Medical Emergencies & Passenger Care

2.3 Onboard Medical Emergencies & Passenger Care

Quick Summary: A medical emergency occurring aboard a moving public service vehicle creates an intense, high-stress environment. The driver instantly becomes the on-scene incident coordinator, responsible for safely navigating the vehicle out of live traffic, managing saloon dynamics, communicating with emergency dispatchers, and providing appropriate care within strict legal boundaries. Knowing the capabilities and statutory limits of the PSV first aid kit, applying vital diagnostic tools like the FAST stroke protocol, and pinpointing vehicle locations on motorways are safety-critical competencies.

Every professional bus and coach driver will inevitably encounter passenger medical emergencies during their career. The spectrum ranges from minor conditions such as motion sickness and fainting to acute, life-threatening crises including grand mal seizures, severe diabetic hypoglycaemia, myocardial infarction (heart attack), stroke, and sudden cardiac arrest.

Handling an onboard crisis requires a dual focus: the driver must preserve road traffic safety by securing the heavy vehicle without causing collisions, while simultaneously ensuring that the casualty receives prompt emergency medical intervention.

Recognizing & Responding to Acute Medical Conditions

When a passenger collapses or displays severe distress, the driver must quickly identify the nature of the condition and initiate appropriate initial action.

  [Cardiac Arrest]                 [Suspected Stroke]     [Diabetic / Seizure]
  - 999 Immediately                - Apply FAST Protocol  - Hypo: Fast sugar
  - CPR (30:2 or continuous)      - Note Onset Time      - Seizure: Cushion head
  - Deploy Defibrillator (PAD)     - Urgent 999 Call      - Clear obstacles

1. Sudden Cardiac Arrest (SCA)

Sudden cardiac arrest occurs when the heart's electrical system malfunctions, causing it to stop pumping blood effectively. Brain death begins within 3 to 4 minutes without intervention.

• Signs: The casualty collapses suddenly, is completely unresponsive, and is not breathing normally (or exhibiting agonal gasps—occasional, noisy gasps for air that must not be mistaken for normal breathing).
• Immediate Actions:
  1. Bring the vehicle to an immediate safe halt, secure the parking brake, and put transmission in neutral.
  2. Immediately delegate a passenger to dial 999 or call dispatch via the emergency terminal.
  3. Commence Cardiopulmonary Resuscitation (CPR) immediately: place the heel of your hand on the center of the casualty's chest, interlock your fingers, and compress firmly at a depth of 5 to 6 cm at a rate of 100 to 120 beats per minute (the tempo of the song "Stayin' Alive").
  4. Deliver 30 chest compressions followed by 2 rescue breaths, or perform continuous hands-only chest compressions if untrained in ventilation or lacking a protective face shield.
  5. If an Automated External Defibrillator (AED / PAD) is carried on the coach or located at a nearby bus station, retrieve it immediately. Turn on the device, apply the pads to the bare chest as illustrated on the packaging, and follow the spoken voice prompts. Defibrillation within the first 3 minutes increases survival rates to over 70%.

2. Stroke Recognition — The FAST Protocol

A stroke occurs when the blood supply to part of the brain is interrupted by a blood clot (ischaemic stroke) or a burst blood vessel (haemorrhagic stroke). Every second lost results in the death of millions of brain cells.

Drivers must master and apply the internationally recognized FAST assessment:

3. Diabetic Emergencies: Hypoglycaemia vs Hyperglycaemia

Diabetes affects the body's ability to regulate blood glucose. On public transport, the most frequent and dangerous acute event is hypoglycaemia (low blood sugar), commonly referred to as a "hypo".

  [Hypoglycaemia (Low Sugar)]        │   [Hyperglycaemia (High Sugar)]
  - RAPID onset (minutes)           │   - SLOW onset (days/hours)
  - Sweating, pale, clammy skin      │   - Dry, flushed skin
  - Shaking, trembling hands        │   - Fruity/pear-drop breath odour
  - Slurred speech, aggression      │   - Heavy, laboured breathing
  - Confusion (looks intoxicated)    │   - Extreme thirst, drowsy

[!CAUTION] The Intoxication Trap: An individual experiencing severe hypoglycaemia often displays slurred speech, uncoordinated movements, confusion, and aggressive irritability. Untrained drivers frequently mistake a diabetic hypo for alcohol or drug intoxication and threaten removal. Always check for a medical alert bracelet, necklace, or glucose monitoring sensor on the passenger's arm before jumping to conclusions.

• Treatment for Conscious Diabetic Casualty: If the passenger is conscious and able to swallow, immediately provide fast-acting sugar: a non-diet sugary drink (fruit juice, standard cola), 4–5 jelly babies, glucose tablets, or sugar lumps dissolved in water. Follow up with longer-acting carbohydrates (a sandwich or biscuits) once symptoms improve.
• Treatment for Unconscious Diabetic Casualty: NEVER put liquids, food, or tablets into the mouth of an unconscious or semi-conscious casualty (choking hazard). Place the casualty in the recovery position, clear the airway, and dial 999 immediately.

4. Seizures & Epileptic Convulsions

A generalized tonic-clonic seizure occurs when abnormal electrical bursts in the brain cause sudden collapse, stiffening of the body (tonic phase), followed by violent rhythmic jerking of the limbs (clonic phase).

• First Aid Actions:
  • Protect from Injury: Move heavy luggage, pushchairs, and sharp objects away from the casualty. Place a soft folded coat, jacket, or bag beneath their head to prevent skull fractures on the hard floor.
  • DO NOT Restrain: Never attempt to pin the passenger down or hold their limbs still. Resisting muscular spasms can cause bone fractures or tendon tears.
  • DO NOT Insert Objects in the Mouth: Never force anything between the passenger's teeth. They will not "swallow their tongue," but inserting fingers, spoons, or pens will fracture teeth or cause airway obstruction.
  • Time the Seizure: Note the exact minute the convulsions start.
• When to Dial 999 for a Seizure:
  1. The active seizure convulsion lasts longer than 5 minutes.
  2. A second seizure starts without the person regaining full consciousness in between.
  3. It is known to be the person's first seizure.
  4. The person has suffered a head injury, is pregnant, or is in water.
  5. The person has difficulty breathing after the shaking stops.
• Post-Seizure Recovery: Once convulsions cease, the casualty enters a post-ictal phase (deep sleep, confusion). Place them gently into the recovery position on their side to keep the airway open and allow fluids/saliva to drain.

5. Fainting (Syncope) & Saloon Overheating

Fainting is a temporary loss of consciousness caused by a transient reduction of blood flow to the brain, commonly triggered by warm, crowded buses, prolonged standing, dehydration, or emotional shock.

• Signs: Pale, sweaty skin, dizziness, yawning, blurred vision, followed by collapse.
• First Aid Action: Lay the casualty flat on their back on the floor or across seats and elevate their legs approximately 30 cm to promote venous blood return to the heart and brain. Ensure fresh air flow by opening roof hatches, side hopper windows, or increasing cab climate control. Loosen tight clothing around the neck.

Safe Stopping Strategy & High-Speed Road Protocols

When a medical crisis occurs, the driver must balance speed of medical response against the catastrophic hazard of stopping a heavy vehicle in a live traffic lane.

  [Medical Alert while Driving]
                │
  ┌─────────────┴─────────────┐
  ▼                           ▼
[Urban / Local Roads]       [Motorways / High-Speed Dual Carriageways]
- Locate nearest bus stop   - NEVER stop in a live running lane
- Pull into lay-by          - Aim for Motorway Service Area (MSA)
- Avoid blocking junctions  - Or Emergency Refuge Area (ERA) / Hard Shoulder
- Keep hazards on           - NO warning triangle (Rule 274)

Stopping on Urban Routes

• Scan ahead for a designated bus stop bay, wide loading lay-by, or quiet side street.
• Avoid stopping directly on pedestrian crossings, within 10 metres of a junction, or blocking narrow streets where approaching ambulances would be unable to pass.
• Apply the spring parking brake, place transmission in neutral, switch on hazard warning lights, and keep the engine running if heating or air conditioning is needed to stabilize the saloon environment.

Stopping on Motorways & Smart Motorways

Stopping a public service vehicle on a high-speed road carries extreme risk of rear-end collision, especially from heavy goods vehicles.

• Live Lane Prohibition: Never stop in a live running lane, even if passengers are shouting or panicked. Stopping in a live lane on a motorway or All Lane Running (ALR) smart motorway creates a lethal risk of high-speed multi-vehicle telescoping collisions.
• Hierarchy of Safe Stopping Places on Motorways:
  1. Best: Leave the motorway at the next exit junction or pull into a Motorway Service Area (MSA).
  2. Second Best: Steer into an Emergency Refuge Area (ERA) on a smart motorway.
  3. Third Best: Pull onto the hard shoulder as far to the left as possible, with wheels turned toward the verge.

[!IMPORTANT] The Warning Triangle Ban on Motorways: Under Highway Code Rule 274, drivers must NEVER place a red warning triangle on a motorway or high-speed dual carriageway. The aerodynamic turbulence from passing 44-tonne HGVs and the extreme danger of walking along a live high-speed shoulder make deploying triangles fatal. Use hazard warning lights and marker lights only.

Contacting 999/112 & Precision Location Reporting

When dialing emergency services in the UK, 999 and 112 are completely equivalent. Both numbers connect to the national emergency operator who routes the call to the appropriate ambulance service dispatch center.

Motorway Driver Location Signs & Marker Posts

On motorways and major A-roads, drivers cannot simply state "I am somewhere near Birmingham on the M6". Ambulance control requires exact, unambiguous geographical location data.

   ┌───────────────────────────┐
   │           M 1             │  ◄── Motorway Road Number
   │            A              │  ◄── Carriageway Identifier ('A' or 'B')
   │         1 4 2 . 6         │  ◄── Kilometre Marker (142.6 km)
   └───────────────────────────┘
    [Blue Driver Location Sign (every 500m)]

• Blue Driver Location Signs: Erected every 500 metres along motorways and major trunk roads. They display three vital pieces of information:
  1. Top Line: The road number (e.g., M1, M4, M62).
  2. Middle Line: The carriageway letter:
     • Carriageway 'A': Typically designates the direction of travel towards London or the origin of the road (or clockwise on the M25).
     • Carriageway 'B': Typically designates the direction away from London or the origin (or anticlockwise on the M25).
     • Carriageway 'M' / 'J': Slip roads leading onto or off junctions.
  3. Bottom Line: The exact location in kilometres and tenths of a kilometre (e.g., 142.6).
• Marker Posts: Small 100-metre distance marker posts located on the verge or barrier repeating the kilometre reading. Quoting M1 Carriageway A km 142.6 allows paramedics to dispatch the nearest ambulance directly onto the correct side of the carriageway without travelling miles past the scene to turn around.

Modern Geolocation: what3words

Emergency services across the United Kingdom now integrate what3words. The system divides the entire globe into a grid of 3-metre by 3-metre squares, each with a unique three-word address (e.g., ///filled.count.soap).

• If operating in rural routes, unnumbered bypasses, or expansive coach parks, providing the emergency dispatcher with the 3-word coordinate from a mobile mapping terminal pinpoints the vehicle entrance door to within three metres.

The METHANE Incident Briefing Protocol

For major incidents or severe multi-casualty emergencies, drivers should structure their verbal report using the METHANE framework:

• M — Major Incident: Is a major incident declaration needed?
• E — Exact Location: Motorway marker post, what3words, junction, or street name.
• T — Type of Incident: Medical collapse, road collision, fire, toxic substance.
• H — Hazards: Fuel leaks, traffic flow, live overhead electric wires, violence.
• A — Access: Safe approach routes for ambulances.
• N — Number of Casualties: Approximate count and severity.
• E — Emergency Services: Which services are on scene or required (Ambulance, Police, Fire).

Statutory PSV First Aid Kit Requirements & Medication Rules

The provision of first aid equipment on public service vehicles is strictly governed by statutory legislation.

The Legal Framework: PSV Equipment Regulations 1981

Under Regulation 42 and Schedule 7 of the Public Service Vehicles (Conditions of Fitness, Equipment, Use and Certification) Regulations 1981 (Statutory Instrument 1981 No. 257), every public service vehicle must carry a designated, fully stocked first aid box.

• Condition: The first aid box must be clearly marked with a standard green cross or the words "First Aid", readily accessible to the crew and passengers, maintained in good condition, and sealed to prevent tampering.
• Inspection: Daily walkaround inspections require the driver to verify that the first aid kit is in place, clean, accessible, and that its tamper-evident seal is intact.

Statutory Minimum Kit Contents

Schedule 7 of the 1981 Regulations specifies the mandatory minimum contents for a PSV first aid kit:

The Strict "No Medication" Legal Rule

One of the most critical legal boundaries tested in CPC examinations is the administration of medication:

$\text{PSV Driver} + \text{Dispensing ANY Pill/Tablet} = \text{CRIMINAL AND CIVIL LIABILITY}$

• Prohibited Items: A PSV first aid box must NEVER contain paracetamol, aspirin, ibuprofen, co-codamol, travel sickness tablets, or prescription medicines.
• Absolute Ban on Administration: Drivers must NEVER administer oral medication to any passenger, under any circumstances, even if an adult passenger begs for a headache tablet or painkiller.
• Legal Liability: If a driver administers an aspirin or paracetamol to a passenger who subsequently suffers an acute anaphylactic allergic reaction, gastrointestinal haemorrhage, or death, the driver and operating company face immediate civil negligence suits and potential criminal prosecution.
• Assisting with Passenger's Own Medication: The ONLY permitted exception is facilitating access to a conscious passenger's own prescribed emergency medication:
  • Handing an asthmatic passenger their own blue Salbutamol inhaler.
  • Handing a passenger with angina their own glyceryl trinitrate (GTN) sublingual spray.
  • Handing a patient with severe allergies their own prescribed adrenaline auto-injector (EpiPen / Jext). The passenger must self-administer the medication unless they are physically incapacitated, in which case the driver should act only under direct, real-time instructions from a 999 ambulance emergency medical dispatcher over the telephone.

Managing Saloon Dynamics & Passenger Welfare

A medical crisis aboard a crowded bus or coach quickly sparks panic, intrusive rubbernecking, and passenger distress. The driver must maintain professional command of the cabin:

1. Public Address Announcements: Speak clearly over the PA system: "Ladies and gentlemen, we are attending to a medical situation with a passenger. The vehicle is safely stationary. Please remain seated and keep the center aisle completely clear for emergency medical personnel."
2. Enlisting Qualified Assistance: Call out politely: "Is there an off-duty doctor, nurse, or trained paramedic on board who can assist?" If a qualified health professional identifies themselves, delegate direct casualty monitoring to them while you manage 999 communication and scene safety.
3. Protecting Dignity and Privacy: Intrusive passengers frequently attempt to photograph or film medical emergencies on smartphones for social media. Drivers must firmly request passengers to cease filming and position coats, blankets, or luggage to shield the casualty's dignity.
4. Depot Liaison & Service Continuity: Alert depot control immediately. If the medical emergency requires an extended ambulance stay (e.g., spinal board extraction or prolonged resuscitation), request a replacement vehicle and driver to transfer unaffected passengers.
5. Drivers' Hours & Tachograph Logging: If an emergency causes a coach driver to exceed permitted driving time limits or delay required breaks under Assimilated Regulation (EC) 561/2006, the driver is legally protected under Article 12 (derogation for emergency safety). The driver must make a manual printout from the digital tachograph immediately upon reaching the safe stopping place, write the full reason on the reverse (e.g., "Stopped at M1 km 142.6 to perform CPR on passenger under 999 instructions"), sign and date the record, and present it for depot compliance logging.

Case Scenario: Motorway Express Coach Acute Stroke Crisis

The Incident

Driver Keith is operating a 53-seat executive coach on the M4 motorway westbound at 65 mph. Ten miles past Junction 14 near Hungerford, a passenger seated in Row 3 runs to the front cab and shouts: "Driver! The lady in seat 4B has collapsed! Her face is twisted, she can't speak, and her right arm has gone completely limp!"

Driver Decision Points & Analysis

 [Unsafe Action]                     [Correct Action]
 Slam brakes on in lane 2           Scan mirrors, indicate left
 Stop on live carriageway           Steer to hard shoulder / ERA
 Deploy warning triangle            Apply parking brake, hazards on
 Give passenger aspirin             Check FAST signs, note onset time
                                     Read marker post km to 999

1. Dynamic Highway Safety: Keith does not brake violently in the active running lane. He indicates left, checks his nearside mirrors, and smoothly guides the coach onto the hard shoulder, pulling as far to the left verge as possible. He places the automatic transmission in neutral, applies the spring parking brake, and switches on the hazard warning lights.
2. Casualty Assessment: Leaving the engine running for saloon air conditioning, Keith steps into the saloon. He observes a 68-year-old female passenger. He applies the FAST protocol: the right side of her face is heavily drooping, her right arm falls completely limp when raised, and when asked her name, she produces only unintelligible slurs. Keith glances at his digital watch: it is precisely 14:22.
3. Precision Emergency Call: Keith directs an off-duty nurse sitting in Row 5 to stay with the casualty, keep her calm, and ensure her airway remains open. Keith returns to the cab, dials 999 on the vehicle emergency hands-free unit, and requests an ambulance. Looking out of the nearside window at the blue marker sign on the verge, Keith states: "This is a 53-seat passenger coach on the M4 Motorway, Carriageway B, at marker post 104.2, five miles west of Junction 14. We have an acute female stroke victim displaying full FAST symptoms. Symptom onset was at 14:18. A trained nurse is monitoring the airway."
4. Refusing Medication: A well-meaning passenger hands Keith two soluble aspirin tablets from their handbag, urging him to dissolve them under the casualty's tongue. Keith immediately refuses: "We must never give medication. If this is a bleeding (haemorrhagic) stroke, aspirin will thin the blood and cause fatal brain haemorrhage. Only the hospital stroke team can administer drugs after a CT scan."
5. Resolution: Because Keith provided the exact carriageway letter and kilometre marker, an NHS rapid response paramedic vehicle travelling westbound pulls directly behind the coach within 8 minutes. Paramedics board, administer oxygen, transfer the casualty via the coach wide entrance door into the ambulance, and convey her under blue lights to the hyper-acute stroke unit at Swindon Hospital. Keith completes his tachograph manual entry under Article 12, logs the incident, and safely resumes the journey.
