Critical CPR first aid steps are the essential techniques used to maintain blood circulation and breathing in someone experiencing cardiac arrest, following the DRSABCD action plan and the 30:2 compression-to-breath ratio. Knowing how to perform cardiopulmonary resuscitation (CPR) can mean the difference between life and death. In Australia, approximately 25,000 people suffer cardiac arrests outside of hospital settings each year, with survival rates heavily dependent on immediate bystander intervention.
The HLTAID009 Provide Cardiopulmonary Resuscitation course equips Sydneysiders with the practical skills and confidence to respond effectively in these critical moments. This comprehensive guide walks you through the essential CPR techniques, ratios, and procedures recognised by the Australian Resuscitation Council, helping to ensure you’re prepared to act when every second counts.

Understanding the DRSABCD Action Plan for Emergency Response
What Does DRSABCD Stand For in First Aid?
DRSABCD is the internationally recognised emergency response protocol taught throughout Australia. This systematic approach ensures rescuers follow the correct sequence when faced with an emergency situation:
Letter | Action | What to Do |
D | Danger | Check for hazards to yourself, bystanders, and the patient |
R | Response | Check if the person is conscious and responsive |
S | Send for help | Call 000 or ask someone else to call |
A | Airway | Open and clear the airway |
B | Breathing | Check for normal breathing |
C | CPR | Start chest compressions if not breathing normally |
D | Defibrillation | Apply an AED (Automated External Defibrillator) if available |
Why DRSABCD is Critical Before Starting CPR
The DRSABCD protocol prevents rescuers from rushing into dangerous situations or performing unnecessary interventions. Checking for danger first protects you from becoming a second victim—you cannot help someone if you’re injured yourself. Assessing responsiveness determines whether the person needs CPR or another form of assistance. A responsive person who’s breathing may simply need monitoring and reassurance, whilst an unresponsive person not breathing normally requires immediate CPR.
The “Send for help” step is particularly crucial in the Australian context, where emergency services response times can vary significantly between urban Sydney and regional areas. Always call 000 before starting CPR when alone, using the phone’s speaker function to keep your hands free. In public spaces, delegate this task to a specific bystander to ensure it gets done.
What Are the 7 Steps of the CPR Process?
Critical CPR First Aid Steps Explained
Step 1 – Check for Danger and Ensure Scene Safety
Before approaching any emergency, scan the environment for potential hazards: traffic, electrical hazards, fire, smoke, unstable structures, or aggressive individuals. At Sydney beaches, this might include rip currents or marine creatures. In urban settings, watch for traffic and broken glass. Only proceed when it’s safe to do so.
Step 2 – Check for Response and Consciousness
Kneel beside the person and gently squeeze their shoulders whilst speaking loudly: “Can you hear me? Are you okay?” If there’s no response, the person is unconscious and requires immediate intervention. Check for normal breathing simultaneously—look, listen, and feel for no more than 10 seconds.
Step 3 – Send for Emergency Help (Call 000)
Call 000 immediately or direct a specific bystander to call. When speaking to the emergency operator, provide:
- Your exact location (street address, landmarks, or GPS coordinates)
- The person’s condition (unresponsive, not breathing)
- Your contact number
- Follow any instructions the operator provides
Step 4 – Open the Airway Properly
Place one hand on the person’s forehead and gently tilt their head back. Use your other hand to lift their chin forward. This head-tilt, chin-lift manoeuvre opens the airway by moving the tongue away from the back of the throat.
Step 5 – Check for Normal Breathing
With the airway open, look for chest rise, listen for breath sounds, and feel for air movement on your cheek. Spend no more than 10 seconds on this check. Occasional gasps (agonal breathing) are not normal breathing and indicate the need for CPR.
Step 6 – Begin Chest Compressions
Position yourself vertically above the person’s chest. Place the heel of one hand on the centre of their chest (lower half of the sternum), then place your other hand on top and interlock your fingers. Keep your arms straight and use your body weight to compress the chest 5-6 centimetres deep at a rate of 100-120 compressions per minute.
Step 7 – Deliver Rescue Breaths
After 30 compressions, give 2 rescue breaths. Maintain the head-tilt, chin-lift position, pinch the person’s nose closed, seal your mouth completely over theirs, and blow steadily for about one second. Watch for the chest to rise. Give a second breath, then immediately return to compressions.
What Are the 3 C’s in CPR and Why Do They Matter?
Check – Assessing the Victim’s Condition
The first “C” involves thoroughly checking the person’s responsiveness and breathing status. This prevents you from performing CPR on someone who doesn’t need it—a responsive person or someone breathing normally requires different care. Proper assessment takes only seconds but determines your entire course of action.
Call – Activating Emergency Services
The second “C” ensures professional help is on the way. In Australia, paramedics carry advanced life support equipment including medications and defibrillators that dramatically improve survival odds. The sooner they’re called, the sooner they arrive. The 000 operator can also provide real-time CPR instructions if you’re uncertain.
Compress – Performing Effective Chest Compressions
The third “C” represents the most critical component of CPR. High-quality chest compressions manually pump blood through the body, delivering oxygen to the brain and vital organs. Research shows that compressions are more important than rescue breaths, which is why hands-only CPR is acceptable for untrained rescuers or those unwilling to give breaths.
What Is the Correct Ratio for CPR? Understanding 30:2 Compression to Breath Ratio
Is CPR Always 30 Compressions to 2 Breaths?
For most situations, yes—the 30:2 ratio is the Australian standard for single-rescuer CPR on adults, children, and infants over 28 days old. However, variations exist:
(ANZCOR/ARC Standards)
| Patient Type | Rescuers | Ratio (Standard BLS) |
|---|---|---|
| Adult | 1 or 2 rescuers | 30:2 |
| Child (1-8 years) | 1 or 2 rescuers | 30:2 |
| Infant (<1 year) | 1 rescuer | 30:2 |
| Infant (<1 year) | 2 healthcare pros | 15:2 |
Healthcare providers trained in CPR may use 15:2 for children when two rescuers are present, allowing for more frequent ventilations in patients whose cardiac arrest is more likely to be respiratory in origin.
How to Maintain the Proper CPR Cycle
Each CPR cycle consists of 30 compressions followed by 2 breaths, taking approximately 24 seconds. After five complete cycles (about two minutes), briefly reassess for signs of life—normal breathing or movement. If absent, immediately resume CPR. Don’t interrupt compressions for more than 10 seconds except when delivering breaths or applying an AED.
To maintain the correct compression rate of 100-120 per minute, many instructors recommend songs with matching beats: “Stayin’ Alive” by the Bee Gees, “Hard to Handle” by The Black Crowes, or “Quit Playing Games (With My Heart)” by Backstreet Boys all work perfectly.

Critical CPR Technique: Proper Chest Compression Depth and Rate
How Deep Should Chest Compressions Be?
For adults, chest compressions must be 5-6 centimetres deep—approximately one-third of the chest depth. This depth is necessary to generate sufficient blood flow through the heart and to the brain. Shallow compressions are ineffective and won’t maintain vital organ perfusion.
After each compression, allow the chest to fully recoil. Don’t lean on the chest between compressions, as this prevents the heart from refilling with blood. Full recoil is just as important as adequate depth.
For children (1-8 years), compress approximately 5 centimetres or one-third of the chest depth. For infants (under 1 year), use two fingers to compress approximately 4 centimetres or one-third of the chest depth.
What Is the Ideal Chest Compression Rate Per Minute?
The Australian Resuscitation Council recommends 100-120 compressions per minute for all age groups. This rate optimises blood flow whilst being sustainable for rescuers over extended periods. Research shows that compressions faster than 120 per minute reduce depth and effectiveness, whilst slower rates don’t generate adequate circulation.
Maintaining this pace for several minutes is physically demanding. In a two-rescuer situation, switch roles every two minutes to prevent fatigue and maintain compression quality. Even brief reductions in compression depth significantly impact survival outcomes.
Should I Stop CPR If the Person Vomits? Handling Common CPR Complications
What to Do When Vomiting Occurs During CPR
Vomiting during CPR is common and occurs in approximately 30% of cases. Do not stop CPR entirely. Instead, follow these steps:
- Quickly turn the person onto their side (recovery position)
- Clear visible vomit from the mouth with your fingers or cloth
- Roll them back onto their back
- Resume CPR immediately
The entire process should take no more than 5-10 seconds. Prolonged interruptions dramatically reduce survival chances. If vomiting recurs, repeat the process. Consider hands-only CPR if you’re unable or unwilling to continue rescue breaths after vomiting occurs.
Other CPR Complications and How to Manage Them
Rib Fractures: Cracking sounds or sensations during compressions are common, especially in older adults with fragile bones. This doesn’t mean you’re doing CPR incorrectly—it indicates you’re achieving adequate depth. Continue compressions without reducing depth or force. Rib fractures heal; death doesn’t.
Regurgitation: Passive flow of stomach contents differs from active vomiting. If small amounts of fluid appear in the mouth, clear it during the transition to rescue breaths without fully stopping compressions.
Gastric Distension: Excessive rescue breath volume can inflate the stomach, increasing vomiting risk. Prevent this by delivering breaths over one second each, just enough to make the chest rise visibly.
Physical Exhaustion: CPR is extremely tiring. If you’re alone and becoming exhausted, continue compressions without breaths rather than stopping entirely. Hands-only CPR is better than no CPR.
When to Stop Performing CPR: Knowing the Right Time
Signs That Indicate You Can Stop CPR
Continue CPR until one of these four conditions occurs:
- The person shows signs of life: Normal breathing returns, they move purposefully, or they regain consciousness
- Advanced help arrives: Paramedics or other qualified medical personnel take over
- The scene becomes unsafe: Fire, structural collapse, aggressive individuals, or other dangers threaten your safety
- You’re physically unable to continue: Complete physical exhaustion makes effective compressions impossible
In Australia, triple zero operators often provide ongoing instructions and encouragement. They’ll tell you when paramedics are close and may coach you through CPR until help arrives. Don’t stop simply because you’re tired—push through if safely possible. The person’s only chance of survival depends on your continued efforts.
If an AED analyses the heart rhythm and advises “no shock needed,” continue CPR. This message doesn’t mean the person has recovered; it means their heart rhythm isn’t currently shockable. Maintain CPR until paramedics arrive or signs of life appear.

Frequently Asked Questions About Critical CPR First Aid Steps
What are the 7 steps of the CPR process?
The seven steps are: (1) Check for danger, (2) Check for response, (3) Send for help by calling 000, (4) Open the airway using head-tilt chin-lift, (5) Check for normal breathing, (6) Begin chest compressions at 5-6 cm depth, and give 2 rescue breaths after 30 compressions(7) Apply an AED when available. These steps follow the DRSABCD protocol and should be performed in sequence. After starting CPR, continue the 30:2 cycle of compressions to breaths until help arrives or the person shows signs of life.
Should I stop CPR if the person vomits?
No, do not stop CPR if vomiting occurs. Quickly turn the person onto their side, clear any visible vomit from their mouth, roll them back onto their back, and immediately resume CPR. This interruption should last no more than 5-10 seconds. Vomiting happens in approximately 30% of CPR cases and is a common complication. If you’re uncomfortable continuing rescue breaths after vomiting, switch to hands-only CPR (continuous chest compressions without breaths), which is still highly effective.
What is the correct ratio for CPR in Australia?
The standard CPR ratio in Australia is 30 chest compressions to 2 rescue breaths (30:2) for adults, children, and infants when one rescuer is performing CPR. This ratio applies whether you’re helping an adult, child (1-8 years), or infant (under 1 year). When two health professionals are present for a child or infant, the ratio may change to 15:2 to provide more frequent ventilations. Each complete cycle of 30 compressions and 2 breaths takes approximately 24 seconds.
Can I perform CPR if I'm not certified?
Yes, Australian Good Samaritan laws protect people who provide emergency assistance in good faith. If someone is unresponsive and not breathing normally, performing CPR—even if you’re untrained—gives them a chance at survival. If you’re uncertain about rescue breaths, perform hands-only CPR (continuous chest compressions at 100-120 per minute). The 000 operator can guide you through the process. However, proper training through HLTAID009 significantly improves your technique and confidence, making you far more effective in a real emergency.
How long does HLTAID009 certification last?
HLTAID009 certification is valid for 12 months from the date of issue. The Australian Resuscitation Council recommends annual CPR refresher training because skills deteriorate over time and guidelines occasionally change. Many workplaces require employees to maintain current certification, meaning you must complete a refresher course before your certificate expires. First Aid Pro Sydney offers quick refresher courses designed for previously certified individuals, making it easy to stay current with minimal time commitment.
