Head Tilt-Chin Lift
Head Tilt-Chin Lift
A method for opening the airway by tilting the head back and lifting the chin. It is recommended for most victims unless a head or neck injury is suspected.
Jaw Thrust
Jaw Thrust
A method for opening the airway used when a head or neck injury is suspected. It involves placing your fingers under the victim's jaw and lifting to displace the jaw forward.
Giving Breaths
Giving Breaths
The process of giving artificial breaths to a victim who is not breathing.
Automated External Defibrillator (AED)
Automated External Defibrillator (AED)
A device that can analyze a person's heart rhythm and deliver an electric shock to restore normal heart function.

Why is it essential to start CPR right away?
Why is it essential to start CPR right away?
The key to successful CPR is to start compressions immediately without delay. This maximizes the chances of restoring blood flow to vital organs.

What is the primary goal of CPR?
What is the primary goal of CPR?
The main purpose of CPR is to circulate oxygenated blood to the brain and heart when the heart has stopped beating. This helps to delay tissue damage and allows time for more advanced medical interventions.

Can CPR restart the heart on its own?
Can CPR restart the heart on its own?
CPR alone is generally not enough to restart the heart. It's crucial to call Emergency Medical Services(EMS) for prompt medical assistance

What does the C-A-B sequence in CPR stand for?
The 2010 AHA guidelines recommend the C-A-B sequence in CPR, which involves prioritizing chest compressions over airway opening.

Where should you place your hands during CPR?
When performing CPR, the correct position is to place the heel of your hand on the center of the chest, just below the sternum, with your arms straightened.

What is the right depth of compressions during CPR?
What is the right depth of compressions during CPR?
For effective CPR, aim for a compression depth of at least 5 cm in adults and children. For infants, the depth should be about 1 / 3 of the chest diameter.

Cardiopulmonary Resuscitation (CPR) Overview
- CPR is an emergency procedure used to manually preserve brain function during cardiac arrest.
- Its main purpose is to restore partial oxygenated blood flow to the brain and heart, thereby delaying tissue death and increasing the survival chance without permanent brain damage.
- CPR alone is unlikely to restart the heart.
CPR Steps
- Check response and scan for breathing: Assess responsiveness and breathing.
- Check pulse: Feel for a pulse for 5-10 seconds. If no pulse is found, begin CPR.
- Activate emergency response system (ERS) and get AED: If possible, ask another rescuer to activate the ERS and get an AED (Automated External Defibrillator).
- If alone: Prefer calling ERS and getting an AED rather than treating the victim.
CPR Techniques
-
Start Chest Compressions:
- Position yourself at the victim's side.
- Ensure the victim is lying face-up on a firm, flat surface.
- Place the heel of one hand on the center of the victim's chest, on the lower half of the sternum.
- Straighten your arms and position your shoulders directly over your hands.
- Perform 30 compressions and 2 breaths repeatedly in cycles. Aim for high-quality CPR.
-
Opening the Airway:
- Employ the Head Tilt-Chin Lift (if no head or neck injury suspected) or Jaw Thrust methods.
- Place one hand on the victim's forehead and push with your palm to tilt the head back. Place the other hand under the bony part of the lower jaw to lift.
- Lift the jaw to bring the chin forward, relieving airway obstruction.
-
Giving Breaths:
- Employ Mouth-to-Mouth, Mouth-to-Mask, or Bag-and-Mask breathing techniques.
High-Quality CPR
- Start within 10 seconds of recognizing arrest.
- Compressions should be performed at a rate of at least 100 per minute.
- Compressions should be forceful enough to compress the chest at least 5 centimeters in adults, 5 cm in children, and 4 cm in infants.
- Allow for complete chest recoil between compressions.
- Minimize interruptions during CPR.
AED Use
- Turn on the AED.
- Attach pads to the victim's bare chest.
- Connect the cables.
- Analyze the rhythm.
- Deliver a shock if advised by the AED.
- Resume CPR immediately following a shock.
CPR for Specific Populations
- Children (one-handed chest compressions)
- Infants (modified chest compressions)
Special Situations
- Hairy chest
- Water
- Transdermal drugs
- Implanted PMs and ICDs
