Place the heel of one hand over the lower part of the breastbone - avoid the little tip of the breastbone because it breaks easily. Place your other hand over the first hand and twine your fingers together to make your hands stronger. Keep your elbows straight and bend from the waist to press down 2 inches. Let the chest rise completely between compressions. You should do 30 compressions at a time, with 2 breaths in between the sets of compressions.
If you draw a line between the nipples, where they intersects the breastbone.
compression in 5 cycles
the guidelines for adults, children and infants is 30 chest compressions to 2 rescue breaths.
During chest compressions, you should compress the chest at least 2 inches (5 cm) deep for adults, while allowing full recoil between compressions. For children, compressions should also be about 2 inches, and for infants, approximately 1.5 inches (4 cm). The compressions should be performed at a rate of 100 to 120 compressions per minute. Proper depth and rate are crucial for effective blood circulation during cardiopulmonary resuscitation (CPR).
The amount of chest compressions given in a set amount of time. Usually 100 a minute for adults.
When performing compressions on child or infant casualties the depth of compressions should be a third of the depth of an adult, all whilst being at the same rate of 100-120 compressions per minute at a rate of 30/2.
Generally, you need to give compressions at a rate of 100 per minute to fully circulate the blood. That's depressing 1/3 of the depth of the chest for adults, and 1/4 of the chest depth for infants and children.
30 chest compressions before sweeping the mouth.
In CPR, chest compressions should be performed at a rate of 100 to 120 compressions per minute, with a depth of about 2 to 2.4 inches (5 to 6 cm) for adults. Compressions should allow the chest to fully recoil between compressions, and rescuers should minimize interruptions during the process. If possible, aim for a compression-to-ventilation ratio of 30:2 for adults, and ensure that compressions are delivered in a straight, firm manner. For infants and children, adjustments in compression depth and technique may be necessary to suit their size.
There are 30 chest compressions between ventilation's for 1-rescuer CPR.
The recommended depth of chest compressions in adult CPR is 2 inches
