Sudden Cardiac Arrest in the Workplace and Effective Solutions with AED & CPR | Wellbeing

This article provides an in-depth analysis of the causes and consequences of sudden cardiac arrest in the workplace, alongside the most practical and effective solution available today: the integration of Cardiopulmonary Resuscitation (CPR) and Automated External Defibrillators (AED)—two highly recommended skills in occupational safety.

1. Sudden Cardiac Arrest in the Workplace: Causes and Severity

Sudden Cardiac Arrest occurs when the heart unexpectedly stops beating effectively, halting blood flow to the brain and other vital organs. Unlike a heart attack (myocardial infarction), SCA can occur without any prior history of cardiovascular disease. In the occupational environment, common risk factors include:

• Prolonged stress and overexertion.

• Hot, poorly ventilated, or oxygen-deficient environments (e.g., factories, cold storage).

• Occupational accidents (electrocution, toxic gas poisoning, blunt chest trauma).

• Uncontrolled underlying conditions (hypertension, diabetes, arrhythmias).

The "golden window" to save a life lasts merely 4 to 6 minutes. After 4 minutes, the brain begins to suffer irreversible damage; after 10 minutes without intervention, the survival rate drops to near zero. Therefore, equipping workplaces with AEDs and training employees in CPR are considered paramount measures for enterprises to proactively protect their workforce's lives.

2. CPR (Cardiopulmonary Resuscitation): The "Backbone" of First Aid

CPR is a lifesaving technique combining external chest compressions and artificial ventilation to temporarily maintain blood circulation and oxygenation when the heart has stopped.

According to the updated 2020-2025 guidelines by the American Heart Association (AHA), which are also recommended by the Vietnamese Ministry of Health:

• Compression-to-Ventilation Ratio: 30 compressions to 2 rescue breaths (30:2).

• Compression Rate: 100-120 compressions per minute.

• Compression Depth: 5-6 cm for adults, 4-5 cm for children.

• Minimizing Interruptions: Do not interrupt chest compressions for more than 10 seconds.

In the workplace, CPR-trained employees can initiate lifesaving measures immediately without waiting for a doctor. Numerous studies demonstrate that timely bystander CPR increases the survival rate by two to three times compared to cases where victims simply wait for an ambulance.

3. AED (Automated External Defibrillator): The Ultimate Lifesaving "Weapon"

An AED is a portable medical device capable of analyzing the heart's rhythm and automatically delivering an electrical shock (defibrillation) if it detects ventricular fibrillation (the most common cause of sudden cardiac arrest).

The greatest advantage of an AED is its universal usability—anyone can use it, even without prior medical expertise. The devices provide clear, step-by-step voice prompts in localized languages. By simply following the audio instructions, a bystander can safely save a victim's life.

International statistics reveal that when CPR and an AED are utilized within the first 3 minutes, the survival rate can reach up to 70%. Conversely, every minute of delay reduces the chance of survival by 7-10%.

Currently, many forward-thinking enterprises in Vietnam are proactively equipping their facilities with AEDs to enhance their emergency response capabilities. For instance, 21 international and major domestic airports have installed AEDs in public and staff areas; high-end office buildings, shopping malls, and 5-star hotels feature them in main lobbies and high-traffic floors; and large manufacturing plants in industrial zones are installing AEDs in medical rooms, production lines, and cafeterias.

4. Practical Benefits of Implementing CPR & AED Programs in Enterprises

Investing in a corporate CPR and AED program yields profound, tangible benefits:

• Drastically Reducing Mortality and Severe Sequelae: The most critical benefit is saving lives. With trained personnel and ready-to-use AEDs, intervention within 3-5 minutes can boost survival rates to 50-70%. This prevents irreversible neurological damage, paralysis, and cognitive decline—common consequences of prolonged cerebral hypoxia.

• Reducing Occupational Accident Compensation Costs: Rapid intervention minimizes medical expenses, long-term sick leave, and production disruptions, thereby lowering statutory compensation liabilities.

• Fostering Employee Loyalty and Peace of Mind: When workers see that their employer invests in AEDs and periodic CPR training, they feel genuinely cared for and protected. This elevates morale, reduces turnover rates, and cultivates deep-rooted loyalty.

• Enhancing Brand Image and CSR: Proactively equipping AEDs and training staff positions the enterprise as a humane, responsible, and highly professional organization. In today's market, Corporate Social Responsibility (CSR) and a strong safety culture are highly valued by candidates, partners, and clients.

• Exceeding International Safety Standards: Implementing CPR & AED programs helps businesses meet and surpass standards like ISO 45001. Multinational corporations often prioritize suppliers and partners with advanced health risk management systems.

5. How to Effectively Implement a Corporate CPR & AED Program

Step 1: Conduct Risk and Needs Assessments

First, survey and assess the risk of sudden cardiac arrest across all work areas. Consider the workforce size, industry nature (construction, manufacturing, office), work environment (heat, high stress, electrical/chemical exposure), and the prevalence of underlying health conditions among staff. This determines the optimal number of AEDs required and the priority groups for training.

Step 2: Establish Policies and Implementation Plans

Draft an internal policy regarding the "Corporate CPR & AED Program," clearly defining the responsibilities of the Board of Directors, the HSE Department, and employees. The plan must outline objectives, budget, rollout timelines, and KPIs (e.g., percentage of trained staff, achieving an emergency response time of under 3 minutes).

Step 3: Equip AEDs and First Aid Supplies

Install AEDs in highly accessible, visible locations near densely populated areas (main entrances, cafeterias, main factory floors) with clear signage. Each device requires monthly checks for battery and electrode pad integrity. Concurrently, equip fully stocked first aid kits pursuant to Circular 19/2016/TT-BYT, including CPR support tools like pocket masks and medical gloves.

Step 4: Organize Periodic Training and Drills

This is the most crucial step. Partner with reputable organizations (hospitals, the Red Cross, professional first aid training centers) to conduct CPR & AED courses for all employees at least once a year. The core First Aid Response Team should undergo advanced training twice a year. The curriculum must blend theory with hands-on mannequin practice, ensuring 100% of attendees can correctly perform CPR and operate an AED.

Step 5: Form a Dedicated First Aid Response Team

Every enterprise should establish a designated first aid team with a ratio of at least 1 certified responder per 25 employees (as legally mandated). This team is responsible for inspecting equipment, leading drills, and acting as the first line of defense during emergencies.

Step 6: Conduct Regular Scenario Drills and Continuous Improvement

Quarterly, or at least twice a year, stage realistic sudden cardiac arrest response drills. Follow each drill with a debriefing session to record response times, identify strengths and weaknesses, and continuously refine emergency protocols.

Step 7: Integrate into Corporate Culture

For long-term sustainability, continuously communicate the program via internal newsletters and workshops, and integrate CPR & AED awareness into the onboarding process for new hires. Recognizing and rewarding active participants will elevate the safety awareness and responsibility of the entire workforce.
