chest compressionAbbreviation: CC
Forcible depression of the thorax during cardiopulmonary resuscitation. This technique is used to circulate the blood of a patient whose heart is no longer beating effectively enough to sustain life.
Effective chest compressions in an adult should depress the sternum by 1.5–2 in (4–5 cm). In a child or infant, the sternum should be depressed by the rescuer to a depth of about 1/2 to 1/3 the depth of the chest.
See also: compression
a means of external cardiac massage; most likely to be effective in small dogs and cats, but very difficult in large animals.
common in horses and cattle, damage to the underlying chest wall with communication to the pleural cavity and pneumothorax is the main danger.
