8.2 Medical Emergencies, CPR/AED & Trauma First Aid

8.2 Medical Emergencies, CPR/AED & Trauma First Aid

Quick Answer: In medical emergencies, security officers must ensure scene safety and Body Substance Isolation (BSI) before initiating the C-A-B (Circulation, Airway, Breathing) assessment. Adult CPR requires 100–120 compressions/minute at a depth of 2.0–2.4 inches and a 30:2 ratio with prompt AED pad placement. Severe arterial bleeding requires immediate application of a commercial tourniquet 2–3 inches above the wound with time documented. Suspected opioid overdoses must receive 4 mg intranasal Naloxone under PA Act 139 immunity, and good-faith emergency care is protected under 42 Pa.C.S. § 8332.

Legal Protections, Consent & Standards of Care in Pennsylvania

When responding to medical emergencies on client property, security officers must operate within established legal doctrines governing medical intervention and emergency civil liability.

1. Pennsylvania Good Samaritan Immunity (42 Pa.C.S. § 8332)

The provision that protects a security officer rendering aid is 42 Pa.C.S. § 8332, "Emergency response provider and bystander good Samaritan civil immunity." (Do not cite 42 Pa.C.S. § 8371 — that section is about bad-faith actions on insurance policies and has nothing to do with first aid.) Section 8332(a) provides:

"Any person, including an emergency response provider, whether or not trained to practice medicine, who in good faith renders emergency care, treatment, first aid or rescue at the scene of an emergency event or crime or who moves the person receiving such care, first aid or rescue to a hospital or other place of medical care shall not be liable for any civil damages as a result of rendering such care, except in any act or omission intentionally designed to harm or any grossly negligent acts or omissions which result in harm..."

• Scope of Protection: Immunity protects responders acting without gross negligence or acts intentionally designed to harm. As amended, the general rule in § 8332(a) turns on good faith, not on whether the responder was paid or trained — a point candidates often get backwards. Related sections cover physicians (§ 8331), AED use (§ 8331.2), and the statute does not relieve a driver of an ambulance or rescue vehicle of liability arising from operating the vehicle (§ 8332(c)).
• Standard of Care: Responders must provide care consistent with their training level (e.g., standard AHA/Red Cross First Aid/CPR/AED certification) without attempting invasive medical procedures exceeding their scope of training.

2. Expressed vs. Implied Consent

• Expressed (Informed) Consent: Must be obtained from every conscious, competent adult prior to touching or administering first aid. The officer should identify themselves ("I am Security Officer Davis, trained in first aid") and ask for permission to assist ("Can I help you?").
• Implied Consent: Legally presumed when a victim is unconscious, unresponsive, confused, or suffering from altered mental status due to trauma or illness, or when the patient is an unaccompanied minor with a life-threatening medical emergency. Under the law, it is presumed that a reasonable person in that condition would consent to lifesaving emergency care.

3. Duty of Care & Prohibition of Abandonment

Once a security officer initiates physical first aid, CPR, or trauma intervention, they have established a legal duty of care. The officer must not abandon the patient until:

• Care is formally transferred to arriving emergency personnel of equal or higher medical certification (e.g., EMS paramedics, emergency physicians).
• The scene becomes unsafe, presenting an immediate threat to the rescuer's life.
• The rescuer becomes physically exhausted and unable to continue.

Prematurely stopping care or walking away from a distressed patient constitutes medical abandonment, exposing the officer and employer to significant civil and criminal liability.

Scene Safety, Universal Precautions & Primary Assessment (C-A-B)

1. Scene Size-Up & Body Substance Isolation (BSI)

Before making physical contact with any patient, security personnel must conduct a rapid 360-degree scene size-up:

• Environmental Hazards: Check for live electrical wires, toxic gas vapors, fire, structural collapse, passing vehicle traffic, or violent assailants.
• Body Substance Isolation (BSI) / Universal Precautions: Under OSHA Bloodborne Pathogens standards (29 CFR 1910.1030), treat all human blood and bodily fluids as potentially infectious (HIV, Hepatitis B, Hepatitis C). Officers must don nitrile gloves, safety goggles/face shields, and use disposable pocket masks or bag-valve masks with one-way filter valves during artificial respirations.

2. The Primary Assessment: C-A-B Sequence

In accordance with American Heart Association (AHA) emergency cardiovascular care guidelines, responders prioritize the C-A-B sequence over the traditional A-B-C model to minimize delays in critical chest compressions:

                          PRIMARY ASSESSMENT (C-A-B)
 ┌───────────────────────────────────────────────────────────────────────────┐
 │ [C] - CIRCULATION / COMPRESSIONS: Check carotid pulse (<10 sec); if absent│
 │       or gasping, initiate high-quality chest compressions immediately    │
 ├───────────────────────────────────────────────────────────────────────────┤
 │ [A] - AIRWAY: Open airway using Head-Tilt/Chin-Lift (or Jaw-Thrust if     │
 │       cervical spinal trauma is suspected); clear visible obstructions    │
 ├───────────────────────────────────────────────────────────────────────────┤
 │ [B] - BREATHING: Deliver 2 rescue breaths (1 second each) watching for    │
 │       visible chest rise; avoid excessive or forceful hyperventilation    │
 └───────────────────────────────────────────────────────────────────────────┘

Adult CPR & Automated External Defibrillator (AED) Protocols

Sudden cardiac arrest requires immediate intervention to maintain cerebral and coronary perfusion. Brain death begins within 4 to 6 minutes of circulatory arrest without CPR.

1. Cardiac Arrest Recognition

• Verify unresponsiveness by tapping shoulders and shouting ("Are you okay?").
• Simultaneously check for normal breathing and feel for a carotid pulse for at least 5 but no more than 10 seconds.
• Note: Agonal gasps (irregular, gasping, snorting breaths) are signs of cardiac arrest, not normal breathing. If the patient is unresponsive and has no pulse (or you are uncertain), initiate CPR immediately.

2. High-Quality Chest Compression Parameters

• Hand Placement: Heel of one hand on the center of the bare chest (lower half of the sternum/breastbone), second hand interlaced on top.
• Compression Rate: 100 to 120 compressions per minute (matching the tempo of the song "Stayin' Alive").
• Compression Depth: At least 2.0 inches (5 cm) but no more than 2.4 inches (6 cm) in adults.
• Complete Chest Recoil: Allow the chest to fully expand between compressions; leaning on the chest prevents coronary artery refill.
• Minimize Interruptions: Keep pauses between compression cycles strictly under 10 seconds.
• Ratio: 30 compressions to 2 rescue breaths for single rescuers and two rescuers in adult CPR.

                       ADULT CPR CYCLE (30:2 RATIO)
 ┌──────────────────────────────────────┬────────────────────────────────────┐
 │         30 CHEST COMPRESSIONS        │          2 RESCUE BREATHS          │
 │  • Depth: 2.0 – 2.4 inches (5–6 cm)  │  • 1 second per breath with pocket │
 │  • Rate: 100 – 120 compressions/min  │    mask or barrier device          │
 │  • Allow full chest recoil           │  • Watch for visible chest rise    │
 └──────────────────────────────────────┴────────────────────────────────────┘

3. Automated External Defibrillator (AED) Deployment

An AED delivers an electrical shock to stun a heart in lethal arrhythmias—Ventricular Fibrillation (V-Fib) or Pulseless Ventricular Tachycardia (V-Tach)—allowing the normal pacemaker to restore an organized rhythm.

• Step 1: Power On: Turn on the AED immediately upon arrival.
• Step 2: Pad Placement: Apply self-adhesive pads to bare, dry skin:
  • Upper Right Pad: Placed directly below the right collarbone (clavicle).
  • Lower Left Pad: Placed on the lower left lateral ribcage (mid-axillary line, below the armpit).
  • Special Conditions: Wipe wet chests dry; shave dense chest hair if pads fail to adhere; position pads at least 1 inch away from implanted pacemakers or medication patches.
• Step 3: Rhythm Analysis: Loudly call "Clear!" and ensure no one is touching the patient while the AED analyzes the cardiac rhythm.
• Step 4: Shock Delivery: If a shock is advised, confirm everyone is completely clear ("Stand clear!") and press the flashing shock button (or allow automatic discharge).
• Step 5: Immediate Resumption: Immediately resume 30:2 chest compressions starting with compressions—do not wait or re-check pulse after shock delivery.

Opioid Overdose & Naloxone (Narcan) Administration

Pennsylvania is heavily impacted by the national synthetic opioid crisis (fentanyl, heroin, prescription opioids). Security officers frequently encounter overdose emergencies in public facilities, transit hubs, and retail restrooms.

1. Statutory Authorization & Immunity: PA Act 139

Under Pennsylvania Act 139 of 2014 ("David's Law"), which amended the Controlled Substance, Drug, Device and Cosmetic Act (35 P.S. § 780-101 et seq.), first responders, law enforcement, and members of the public may obtain, carry, and administer naloxone (Narcan) to a person believed to be experiencing an opioid-related overdose. A person who acts in good faith and with reasonable care is immune from criminal prosecution, professional licensing sanction, and civil liability for the act. Receiving training that meets the Act's criteria and promptly seeking additional medical assistance creates a rebuttable presumption that the person acted with reasonable care. Act 139 also gives limited immunity to overdose victims and bystanders who summon help.

2. Clinical Indicators of Opioid Overdose

• The Opioid Triad:
  1. Pinpoint Pupils (Miosis): Severely constricted, tiny pupils.
  2. Severe Respiratory Depression: Dangerously shallow, slow breathing (fewer than 8 breaths per minute) or total apnea (respiratory arrest).
  3. Unresponsiveness / Altered Consciousness: Flaccid muscle tone, inability to be aroused by sternal rubs.
• Associated Signs: Cyanosis (blue or gray discoloration of lips, nailbeds, and skin), cool/clammy skin, and loud snoring or gurgling sounds (often called the "death rattle").

3. Naloxone Administration Protocol

1. Call 911 / EMS immediately.
2. Administer Intranasal Naloxone: Insert the nozzle of a 4 mg pre-packaged nasal spray into one nostril until fingers contact the patient's nose; press the plunger firmly to discharge the entire dose into the nasal mucosa.
3. Support Airway & Breathing: If the patient is not breathing, perform rescue breathing (1 breath every 5 to 6 seconds) or standard CPR if pulseless.
4. Second Dose Timing: If the patient fails to respond or spontaneous breathing does not resume within 2 to 3 minutes, administer a second 4 mg dose in the opposite nostril.
5. Post-Revival Precautions & Recovery Position: Place the reviving patient in the recovery position (lateral recumbent on their side) to prevent aspiration. Naloxone causes immediate, acute opioid withdrawal, which may induce agitation, confusion, combativeness, or vomiting. Naloxone's half-life (30–90 minutes) is shorter than many potent opioids (such as fentanyl), so the patient may slip back into respiratory arrest once the antagonist wears off. Ensure EMS transports the patient to an emergency department.

Life-Threatening Hemorrhage Control & Tourniquet Application

Uncontrolled severe bleeding is the leading cause of preventable death in penetrating trauma (gunshot wounds, stabbings, industrial machinery lacerations). Exsanguination from a severed femoral or brachial artery can cause fatal hypovolemic shock within 2 to 3 minutes.

                               HEMORRHAGE CONTROL PROTOCOL
 ┌─────────────────────────────────────────────────────────────────────────────┐
 │ 1. DIRECT PRESSURE: Immediate firm, two-handed pressure directly over wound │
 ├─────────────────────────────────────────────────────────────────────────────┤
 │ 2. WOUND PACKING: For junctional wounds (groin, axilla, neck), tightly pack │
 │    hemostatic gauze into the bleeding cavity; hold hard pressure for 3 min  │
 ├─────────────────────────────────────────────────────────────────────────────┤
 │ 3. TOURNIQUET (CAT): For life-threatening extremity arterial hemorrhage,    │
 │    apply 2–3 inches above wound (never over a joint); tighten windlass      │
 │    until bleeding stops; lock in clip; document exact time on strap.       │
 └─────────────────────────────────────────────────────────────────────────────┘

1. Types of Bleeding

• Arterial Bleeding: Bright red, oxygen-rich blood that spurts pulsatile in synchronization with the heartbeat. Highest lethality; immediate intervention required.
• Venous Bleeding: Dark red, deoxygenated blood that flows in a steady, continuous stream. Life-threatening if large deep veins (femoral, jugular) are severed.
• Capillary Bleeding: Dark red blood that slowly oozes from superficial abrasions; easily controlled with standard dressing.

2. Commercial Tourniquet (CAT) Application Guidelines

When extremity hemorrhage is severe or arterial, apply a commercial Combat Application Tourniquet (CAT) without delay:

• Placement: Position the band 2 to 3 inches above the bleeding site (proximal to the torso). NEVER place a tourniquet directly over a joint (elbow or knee), as underlying bones prevent arterial compression.
• Hasty Application in Combat/Active Threat: If the exact wound location cannot be clearly identified due to clothing or dark conditions, place the tourniquet "high and tight" at the topmost portion of the injured limb (upper arm or upper thigh).
• Tightening: Pull the self-adhering band as tight as possible before turning the windlass. Twist the rigid windlass rod until the bright red arterial bleeding stops and the distal pulse (radial or pedal) is completely eliminated.
• Securing: Lock the windlass rod inside the windlass clip. Secure the excess strap and windlass safety strap over the clip.
• Documenting Time: Write the exact time of application (e.g., "TK 14:35") directly on the white time strap and on the patient's forehead or triage tag with an indelible marker.
• Strict Rule on Removal: NEVER loosen or remove a tourniquet once applied. Releasing a tourniquet re-initiates massive hemorrhage and releases accumulated metabolic toxins (lactic acid, potassium) into systemic circulation, triggering fatal cardiac arrest. Only qualified surgical or emergency hospital personnel may remove a tourniquet.

Shock Recognition & Emergency Management

Shock (hypoperfusion) is a life-threatening systemic condition where the circulatory system fails to deliver adequate oxygenated blood to vital organs.

1. Types of Shock

• Hypovolemic Shock: Caused by massive blood loss (hemorrhagic) or severe fluid depletion (burns, dehydration).
• Cardiogenic Shock: Caused by heart failure or massive myocardial infarction where the cardiac pump fails.
• Anaphylactic Shock: Severe, life-threatening systemic allergic reaction (bee stings, nuts, medications) causing massive vasodilation and airway bronchospasm.
• Neurogenic / Septic Shock: Caused by spinal cord injury (loss of vascular tone) or overwhelming systemic bacterial infection.

2. Clinical Signs of Shock

• Skin: Pale, cold, clammy, diaphoretic (sweaty), or cyanotic.
• Pulse: Rapid (tachycardia >100 bpm) and weak/thready.
• Respiration: Rapid, shallow tachypnea.
• Mental Status: Restlessness, anxiety, confusion, lethargy, or loss of consciousness.
• Blood Pressure: Decreased systolic blood pressure (a late, decompensated sign).

3. Emergency Shock Management Protocol

1. Maintain airway, breathing, and circulation (C-A-B).
2. Control all external hemorrhage immediately with direct pressure or tourniquets.
3. Position the patient supine (flat on their back). If there is no suspected spinal injury, pelvic fracture, or respiratory distress, elevate the lower extremities 6 to 12 inches to facilitate venous blood return to the heart and brain.
4. Thermal Management: Cover the patient with an emergency hypothermia blanket or coat to preserve body heat. Hypothermia impairs blood clotting factors, dramatically increasing mortality (the trauma "triad of death").
5. Strict Fluid Restriction: NEVER administer oral fluids, food, or water to a patient in shock, regardless of complaints of extreme thirst. Oral intake induces vomiting, creates aspiration pneumonia risks, and complicates emergency anesthesia required for surgical intervention.

Scenario: Loading Dock Severe Extremity Laceration

Scenario: While on patrol at a manufacturing facility, Officer Miller discovers a warehouse worker whose right forearm has been lacerated by an industrial metal sheer. Bright red blood is spurting vigorously in rhythmic pulses across the floor. The worker is pale, dizzy, and in extreme panic. Miller has his duty belt equipped with nitrile gloves and a commercial CAT tourniquet.

Analysis: The rhythmic spurting of bright red blood indicates an arterial laceration (radial/ulnar artery) with imminent risk of fatal exsanguination. Officer Miller must immediately don nitrile gloves (BSI), place the CAT tourniquet 2 to 3 inches proximal to the forearm wound (below the elbow, or high and tight on the upper arm if anatomy requires), and turn the windlass rod until the spurting blood stops and the radial pulse disappears. Miller must then lock the windlass, record the current time (e.g., "TK 09:15") on the tourniquet time strap, keep the worker calm and warm to prevent shock, and maintain care until EMS arrives. Miller must never loosen the tourniquet.

Exam Tip: Tourniquet Time Marking & Narcan Administration Legal Protections

• Document the Time: On the exam, questions regarding tourniquet application frequently emphasize marking the exact time of placement on the device. Never guess or omit the time strap documentation.
• Act 139 Standing Order: Act 139 immunity is conditioned on acting in good faith and with reasonable care, and completing conforming training plus calling for further medical assistance creates a rebuttable presumption that you did. You do not need a personalized prescription to carry or administer employer-issued naloxone under the Physician General's standing order.
