Chest compression is executed by pumping the chest to circulate oxygenated blood throughout the body. Three factors of chest compressions are crucial: hand placement, depth of compression, and compression rate. CPR guideline states to compress the adult chest at a rate of at least 100 compressions per minute, with a compression depth of at least 2 inches/5 cm, and at "the middle of the chest" by AHA guideline 2010.
The aim of the developed system is to estimate the compression action and to provide a feedback to follow the guideline above. Our software was designed to target Android 2.3 and higher.
