ACLS Provider Manual Comparison Sheet Based on 2010 AHA Guidelines for CPR and ECC BLS Changes
New Old
Airway, Breathing, Chest compressions (A-B-C) Previously, after responsiveness was assessed, a call for help was made, the airway was opened, the patient was checked for breathing, and 2 breaths were given, followed by a pulse check and compressions.

Rationale
Although ventilations are an important part of resuscitation, evidence shows that compressions are the critical element in adult resuscitation. In the A-B-C sequence, compressions are often delayed.

CPR

Chest compressions, Airway, Breathing (C-A-B) New science indicates the following order: 1. Check the patient for responsiveness and no breathing. 2. Call for help and get the AED 3. Check the pulse. 4. Give 30 compressions. 5. Open the airway and give 2 breaths. 6. Resume compressions. Compressions should be initiated within 10 seconds of recognition of the arrest.

Compressions were to be given after airway and breathing were assessed, ventilations were given, and pulses were checked.

Compressions should be given at a rate of at least 100/min. Each set of 30 compressions should take approximately 18 seconds or less. Compression depths are as follows: • Adults: at least 2 inches (5 cm) • Children: at least one third the depth of the chest, approximately 2 inches (5 cm) • Infants: at least one third the depth of the chest, approximately 1½ inches (4 cm)

Compressions were to be given at a rate of about 100/min. Each cycle of 30 compressions was to be completed in 23 seconds or less. Compression depths were as follows: • Adults: 1½ to 2 inches • Children: one third to one half the diameter of the chest • Infants: one third to one half the diameter of the chest

Although ventilations are an important part of resuscitation, evidence shows that compressions are the critical element in adult resuscitation. Compressions are often delayed while providers open the airway and deliver breaths.
