ABSTRACT
CHEST COMPRESSIONS ■ Rhythmic pressure over the lower half of the sternum ■ Compression rate of 100/minute ■ Ratio of 15 compressions to 2 ventilations ■ Compress sternum approximately 2 inches and assess ade-
quacy of compression by palpating carotid or femoral pulse. ■ Effective chest compression produces a systolic blood
pressure of about 70 mm Hg and a cardiac output about onethird of normal.
