Key definitions

• Basic Life Support (BLS) - The fundamental emergency procedures to support and sustain life during cardiac arrest or respiratory failure.
• Cardiopulmonary Resuscitation (CPR) - A lifesaving technique involving chest compressions and rescue breaths to maintain blood circulation and oxygenation until advanced medical help arrives.
• Automated External Defibrillator (AED) - A portable device that delivers an electric shock to restore normal heart rhythm during sudden cardiac arrest.

Importance of basic life support

Basic life support is not just a set of skills; it's a critical link in the chain of survival. During medical emergencies such as cardiac arrest or choking, the timely application of BLS techniques can mean the difference between life and death. By understanding and mastering these techniques, individuals can play a vital role in improving outcomes and increasing the chances of survival for those in distress.

Causes of cardiac arrest and respiratory failure

Cardiac arrest can occur suddenly due to various factors, including heart conditions such as coronary artery disease, arrhythmias, or heart attacks.

Respiratory failure may result from drowning, suffocation, or severe allergic reactions, leading to inadequate oxygen supply to the body.

Risk factors and signs and symptoms

Several factors increase the risk of experiencing cardiac arrest or respiratory failure:

• Age - Older adults are at higher risk of cardiac events due to age-related changes in the heart and blood vessels.
• Lifestyle factors - Smoking, poor diet, lack of exercise, and excessive alcohol consumption can contribute to cardiovascular diseases.
• Pre-existing medical conditions - Individuals with conditions such as hypertension, diabetes, or obesity are more susceptible to cardiac events.

Recognising the signs of cardiac arrest or respiratory failure is crucial for prompt intervention: These signs include:

• Unconsciousness
• Absence of breathing or abnormal breathing patterns
• Absence of pulse or irregular heartbeat.

Treatment and management

• Immediate action is essential when faced with a medical emergency.
• Call emergency services immediately to seek professional help.
• Start CPR by performing chest compressions and rescue breaths to maintain circulation and oxygenation.
• Use an AED if available, following the device's prompts for defibrillation.

Prevention strategies

Prevention is key to reducing the incidence of cardiac arrest and respiratory failure:

• Stay informed and educated on basic life support techniques through certified training courses.
• Promote a healthy lifestyle by exercising regularly, maintaining a balanced diet, and avoiding harmful habits like smoking.
• Ensure workplace safety measures are in place and adhere to relevant regulations and guidelines.

Recommendations for basic life support training

• Enrol in a certified basic life support training course to gain the knowledge and confidence needed to respond effectively in emergencies.
• Educate family members, friends, and colleagues about basic life support techniques and encourage them to undergo training.
• Advocate for the availability of AEDs in public spaces and workplaces to increase access to life-saving interventions.
