6.3 Medical Emergencies and Immediate Release

Key Takeaways

  • If a medical emergency is suspected during physical intervention, release immediately — do not continue restraint to “finish the job”.
  • Call a first aider and emergency services without delay; EFAW (or equivalent) knowledge underpins safe handover and life-support decisions.
  • Brief EMS with incident facts, known medical/substance information, behaviour changes, restraint method, duration, injuries and first aid already given.
  • After release, maintain ABC care, recovery position or CPR as indicated, protect from further harm, and keep monitoring until professional handover is complete.
  • Distinguish deliberate non-compliance from medical distress: breathlessness, cyanosis, collapse, incoherence and red flags override ‘ejection first’ thinking.

6.3 Medical Emergencies and Immediate Release

Quick Answer: If you suspect a medical emergency during physical intervention, release immediately, call a first aider and emergency services, give appropriate first aid, and brief EMS with what you know — including how the person was held and for how long. Do not keep restraining to “finish the ejection”.

Dynamic risk assessment and red-flag monitoring only protect people if you act on them. This section turns those checks into clear actions: when to release, how to interface with first aid, what to say to the ambulance crew, and how to avoid the deadly mindset of finishing the job during a crisis.

When to release immediately

Release (or radically reduce restriction) immediately when you reasonably suspect a medical emergency or serious deterioration, including:

  • Difficulty breathing, blocked airway, vomiting that threatens the airway
  • Unconsciousness, non-responsiveness, or sudden passivity after struggle
  • Cyanosis (blueness of lips, face or nails)
  • Signs of heart attack, stroke, severe allergic reaction or major trauma
  • Suspected head or spinal injury where continued manhandling increases harm
  • Suspected overdose with reduced consciousness or irregular breathing
  • Extreme heat illness signs with collapse or confusion
  • Any combination of red flags that indicates life may be at risk

Default rule for the exam and for practice: life and breathing come first. Completing an ejection, proving a point, or “teaching respect” is never a reason to continue a dangerous hold.

There can be rare moments where total release would drop a thrashing person onto a live road or into a glass-filled void for a second or two while you move them a short distance to safety — but that is about immediate environmental danger, not about finishing a disciplinary removal. As soon as a safer surface and space exist, prioritise medical care.

Calling emergency services and the first-aid interface

  1. Release and make the scene as safe as you can (crowd back, hazards away).
  2. Call 999/112 (or your venue’s emergency procedure that reaches ambulance control) for serious medical emergencies.
  3. Call or radio a trained first aider immediately.
  4. Start ABC care: open airway, recovery position if unconscious and breathing normally, CPR and AED if no signs of life / not breathing normally.
  5. Keep someone free to guide emergency responders in and to manage bystanders.

Why EFAW matters

A valid Emergency First Aid at Work (EFAW) certificate (or an accepted equivalent such as FAW, FPOS or FREC) is a mandatory prerequisite: the SIA requires you to hold one, with at least 12 months' validity remaining, before you can take the licence-linked training. That is not bureaucracy for its own sake: PI creates situations where first-aid decisions must be made in seconds. Your PI theory assessment expects you to know when to stop restraining and what life-support priorities are; your first-aid certificate should mean you can deliver those skills. Do not invent techniques outside your training, and do not assume a colleague’s first-aid badge removes your duty to release and call help.

Handover briefing content

When emergency services or a first aider take over, give a clear, factual, calm brief. Include:

Handover itemExamples
What happenedFight at door; ejection attempt; collapse during escort
TimelineStruggle ~3 minutes; unresponsive for ~1 minute
Behaviour before crisisAggressive, then extreme strength, then sudden silence
Known medical / substance info“Said he has asthma”; smell of alcohol; possible cocaine use reported by friend
Restraint methodTwo-person standing escort; brief period on the ground face-down
Duration of restraintApproximate total time under control
Injuries observedBleeding lip; possible head strike on floor
Care already givenReleased, recovery position, oxygen requested, AED attached
Other hazardsHostile crowd, weapons found, wet floor

Method and duration are examinable and clinically important. Positional asphyxia and cardiac arrest risk are linked to restricted breathing and prolonged struggle. Hiding or minimising how the person was held undermines care and later investigation.

Do not “finish the job” during a medical emergency

Common unsafe thoughts — all wrong:

  • “We’re nearly at the exit, just ten more seconds of hold.”
  • “If we let go now they’ll say we lost.”
  • “They’re faking it to avoid being thrown out.”
  • “Police will be annoyed if we release before they arrive.”

If medical emergency signs are present, continuing restraint to complete the removal is professionally and legally dangerous. Necessity and proportionality change the moment the main threat is medical, not assaultive. Your duty of care requires you to prioritise life.

Post-release care

After release:

  • Maintain ABC monitoring without interruption
  • Use the recovery position for unconscious casualties who are breathing normally
  • Start CPR/AED when indicated; follow first-aid training
  • Keep the person warm or cool as appropriate; protect privacy and dignity where possible
  • Prevent further harm: traffic, crowd, cold pavement, secondary assault
  • Do not leave them unattended until handover to a competent person is complete
  • Preserve CCTV/body-worn video and start factual notes as soon as care allows (detailed reporting is covered in the post-incident chapter)
  • Support colleagues who may be shocked — medical emergencies after restraint are high-stress events

Scenarios: non-compliance vs medical distress

Use these contrasts in exam answers and on shift.

Scenario A — likely non-compliance (still monitor)

A refused customer swears, braces in a doorway, and says “you’re not moving me” while speaking full sentences, pink in the face, no vomiting, no cyanosis, and coherent. Options: de-escalate, create space, call colleagues, consider proportionate low-level holds only if necessary and lawful. Monitoring still continues if hands-on control starts.

Scenario B — medical distress during ejection

During a two-person escort the same person suddenly becomes quiet, heavy, blue around the lips, and does not answer. This is not “they’ve calmed down”. Treat as emergency: release, ABC, recovery position or CPR as indicated, first aider and ambulance, brief with method and duration.

Scenario C — “I can’t breathe” while resisting

The subject twists and shouts “I can’t breathe”. Do not automatically treat this as a trick. Reduce pressure on the chest/abdomen, check position, ensure airway is free, consider release or change of hold, call a first aider if doubt remains. Ignoring breathing complaints is a classic failure pattern after restraint-related deaths.

Scenario D — high resistance then collapse (ABD risk profile)

Extreme strength, sweating, hot skin, bizarre behaviour, then sudden exhaustion and collapse. High medical risk. Release, urgent emergency services, first aid, cool environment if heat is a factor, full handover including duration of struggle and holds used.

Scenario E — vomiting while held

Vomiting threatens the airway. Immediate priority: free the airway, change position (not face-down with pressure), release as needed, recovery position if unconscious and breathing, emergency help. Continuing a face-down hold “until they stop fighting” is indefensible.

Throughout any holdABC monitoring and red-flag recognition
On suspected emergencyImmediate release, first aid, EMS, method + duration handover

Reducing harm is not a soft optional extra. It is central to LO3 of the physical intervention unit, to your licence-linked assessment, and to keeping people alive on real doors and events.
