Why is allowing complete chest recoil important while performing high quality cpr?

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).

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
