Most of the time, when trying to revive a patient with chest compressions, the doctors do them much too fast (about five per second, when CPR guidelines are 100 compressions per minute). Swift, shallow compressions don't allow enough blood and oxygen to circulate through the heart and reach the brain.
A palpated blood pressure is obtained by locating the radial pulse and inflating the blood pressure cuff until the pulse disappears. The air is slowly released and the reading is noted when the pulse is again felt. Characters consistently use the term "BP is X over palp." The correct terminology is "BP is X palpated." Secondly, a palpated blood pressure is a last resort and a poor indicator of blood pressure.
