Figure 5-7. Administering a modified chest thrust to an unconscious casualty.
(f) Repeat the modified chest thrusts until the obstruction has been
expelled or until 5 thrusts have been administered.
g. Administer Two Ventilations. After expelling the object or after performing
5 modified abdominal or chest thrusts, open the casualty's airway and attempt to
administer two full breaths (paragraph 3-9).
(1) If your attempts to ventilate are successful, check for spontaneous
breathing. If the casualty does not resume breathing on his own, perform rescue
breathing or CPR as appropriate.
(2) If your attempts are not successful (chest does not rise), continue to
perform finger sweeps and modified thrusts until you are able to ventilate the casualty or
until you are told to stop your efforts by a qualified person.
