CAB Sequence of CPR
What is CAB Sequence of CPR? If you were trained in CPR prior to 2010, you might wonder why did the steps of CPR change to ABCs to CAB Sequence.
According to Highlights of Canadian Consensus Guidelines on First Aid and CPR.The recommended sequence is to initiate chest compressions before giving rescue breaths (C-A-B rather than A-B-C). This approach reduces delay to first compression and pumps oxygenated blood to the body.
Previously CPR training has emphasized the ABCs of CPR, which instructed people to open a victim’s airway by tilting their head back, pinching the nose and breathing into the victim’s mouth, and only then giving chest compressions. This approach caused significant delays in starting chest compressions, which are essential for keeping oxygen-rich blood circulating through the body. As a result, it is now recommended to use CAB Sequence instead of ABCs.
Bystanders should call 9-1-1 immediately, so the dispatcher can help bystanders check for breathing, get the precise location and provide instructions for performing CPR
Interruptions in chest compressions should be minimized. The recommendation for chest compression depth for adults is at least 2 inches (5 cm) but not greater than 2.4 inches (6 cm) at chest compression rate is 100 to 120/min.
When multiple trained rescuers are available, it is recommended that a team approach with clear pre-assigned roles is implemented.
