Chest recoil
is the re-expansion of the chest. Complete recoil is necessary so that the
blood can re-fill the heart’s chambers between compression. Therefore, it is indispensable
because, as the chest is elevated, the negative pressure that is applied
actually causes the blood to be drawn back into the heart and save the life of
someone whose heart stopped or who is in a condition called cardiac arrest. An
activity using a plunger and pulling back on it in water-clogged sink can be
link that will show how important to emphasize complete recoil where it permits
the output of blood in performing a high quality Cardio Pulmonary Resuscitation
(CPR).
