c. Fractures. Fractures of the ribs or sternum may occur even if CPR is
performed correctly. Care should be taking, however, to be sure there is proper hand
placement and technique because fractures of the ribs or sternum (including the
xyphoid process) can lead to punctured lungs; lacerated liver, aorta, stomach, or
spleen; or cardiac tamponade (blood in the pericardial sac) caused by a lacerated
d. Vomiting (Regurgitation). If the casualty vomits, turn his entire body onto
one side and wipe out his mouth. Then, return him to the supine (flat on his back)
position and continue administering CPR.
e. Dentures. Do not remove dentures from the casualty's mouth unless they
are loose or broken. If it is necessary to remove dentures, send them with the casualty
when he is evacuated (put them in his pocket, and so forth).
Generally, these are the only reasons to stop CPR: the rescuer is physically
unable to continue, the rescuer is relieved by a doctor or other medical personnel, a
doctor pronounces the casualty dead, or the casualty revives.
