Children undergoing CPR should receive two breaths after every 30 chest compressions if there is a single rescuer. They should receive the two breaths after every 15 chest compressions if there are two rescuers.
The compression-ventilation ratio for 2-rescuer adult CPR is 30:2. This ratio is the number of compressions (30) and breaths (2) in 1 cycle. The role of the second rescuer at the head during the cycles of compressions to ventilation is to maintain an open airway and give breaths.
2-Rescuer CPR Between the two methods, 2-rescuer CPR is more efficient due to one person performing compressions and another is giving breaths, it's not as tiring and there's less of a delay between compressions and breaths. Therefore, it's more efficient and it's more effective.
Seal your mouth over their mouth and blow steadily and firmly into their mouth for about 1 second. Check that their chest rises. Give 2 rescue breaths. Continue with cycles of 30 chest compressions and 2 rescue breaths until they begin to recover or emergency help arrives.
Infant CPR Ratio: The CPR ratio is 30:2 for a single rescuer, the same as the ratio for adult/child. If there are two rescuers, the CPR ratio for the child and infant will be 15:2. You need to perform 15 chest compressions followed by 2 rescue breaths.
Give the first rescue breath — lasting one second — and watch to see if the chest rises. If the chest rises, give a second breath. If the chest doesn't rise, repeat the head-tilt, chin-lift maneuver and then give a second breath. Thirty chest compressions followed by two rescue breaths is considered one cycle.
Children undergoing CPR should receive two breaths after every 30 chest compressions if there is a single rescuer. They should receive the two breaths after every 15 chest compressions if there are two rescuers.
CPR ratio for one-person CPR is 30 compressions to 2 breaths ▪ Single rescuer: use 2 fingers, 2 thumb-encircling technique or the heel of 1 hand. After each compression, allow complete chest recoil. the person becomes responsive.
Chest Compressions
The compression rate for adult CPR is approximately 100 per minute (Class IIb). The compression-ventilation ratio for 1- and 2-rescuer CPR is 15 compressions to 2 ventilations when the victim's airway is unprotected (not intubated) (Class IIb).
For two-rescuer CPR by health care providers, a compression-to-ventilation ratio of 15:2 is recommended. Once an advanced airway is established, chest compressions are no longer interrupted for ventilation and should be performed at a rate of at least 100 compressions/min.
For children, the compression to breaths ratio is 30:2 for one rescuer and 15:2 for two rescuers for all age groups. The depth of compression may be different. For a child, compress the chest at least one-third the depth of the chest.
1 rescuer: Perform cycles of 30 compressions and 2 breaths. When second rescuer arrives, perform cycles of 15 compressions and 2 breaths.
Infant CPR - 1 Rescuer: Just below the infant's nipples, in the center of the chest, just below the middle horizontal line, place two fingers for compression. Remember, 100-120/min compressions while maintaining the same ratio 30:2 Compression to Breathing.
Provide rescue breathing, 1 breath every 2-3 seconds, or about 20-30 breaths/min. Assess pulse rate for no more than 10 seconds. Continue rescue breathing; check pulse about every 2 minutes. If no pulse, start CPR.
Give 30 compressions followed by 2 breaths, known as “30:2”. Aim for 5 sets of 30:2 in about 2 minutes (if only doing compressions about 100 – 120 compressions per minute).
High-quality CPR performance metrics include: Chest compression fraction >80% Compression rate of 100-120/min. Compression depth of at least 50 mm (2 inches) in adults and at least 1/3 the AP dimension of the chest in infants and children.
CPR is the action of giving 30 compressions followed by 2 breaths. Try to achieve 5 sets of 30:2 in about 2 minutes (or 100–120 compressions/ minute). If unwilling or unable to give breaths, giving compressions only is better than not doing CPR at all.
This is the recommended compression-ventilation ratio for adults according to AHA guidelines. While trained rescuers should use a 30:2 ratio on adult victims, two-rescuer resuscitation on infants and children should follow a ratio of 15:2 or 15 chest compressions followed by two rescue breaths.
When performing CPR on an adult, the rescuer should place their hands in the center of the chest and push down at a rate of 100-120 compressions per minute with a depth of two inches. For a child, the rescuer should use one hand to perform chest compressions with a depth of one and a half inches.
In early guidelines this used to be just two breaths (as in the further sequence) (9). Later paediatric cardiopulmonary resuscitation [CPR] guidelines recommend five attempts to at least deliver two effective ventilations.
Continue to give 1 rescue breath every 5 to 6 seconds, or about 10 to 12 breaths per minute, until the person starts breathing or emergency medical services arrive. Check for a pulse every 2 minutes.
If the person is a baby or child (age 1 to puberty) and they are not breathing but has a pulse, give 1 rescue breath every 2 to 3 seconds or about 20 to 30 breaths per minute.
Firstly, maintaining an adequate ventilation is crucial during CPR in children because pediatric CA is primarily caused by respiratory failure2. The 15:2 ratio delivers more ventilations whereas the 30:2 ratio delivers more chest compressions (CC).
