2-person, closed-chest CPR should be initiated as soon as CPA is declared.
Circulation – Immediately begin sustained, forceful chest compressions with the MWD in lateral recumbency (on either side) at a rate of 100 compressions per minute. Sustain compressions for at least 2-3 minutes per cycle. Hand placement can be directly over the heart (where the elbow crosses the chest above the sternum when the forearm is pulled caudally) or over the widest part of the chest (See Figure 32). Ensure adequate relief of downward pressure during the relaxation phase of the compressions. As for people, “PUSH HARD and PUSH FAST.”1
Airway – Establish an airway as rapidly as possible and as soon as possible after identifying a patient in CPA. However, start chest compressions first! Intubate the MWD if possible; if intubation is not possible, perform an emergent tracheostomy without delay (See CPG 2).
Breathing – Ventilate the patient at a rate of 8-10 breaths per minute. Avoid hyperventilation. Give oxygen if available; room air is acceptable if oxygen is not available.
