Experiment Items | 1stGeneration | 3rdGeneration | Explanation |
---|---|---|---|
Comparison of Coronary Perfusion Pressure (CPP) and required chest compression depth | 12-20 mmHg 5.3 - 6.1 cm |
14-50 mmHg 3.0 - 3.5 cm |
50% compression depth delivered by Weil MCC has the same effect as 100% compression depth delivered by other compressor brand |
Intrathoracic Positive Pressure | 10 mmHg | 31 mmHg | Facilitates blood circulation |
Intrathoracic Negative Pressure | - 3 mmHg | - 10 mmHg | Better for blood perfusion |
Number of Broken Ribs | Average 2.75 | Nil | Less to none complication and injury |
48 hours after ROSC on Neurobehavioral Assessment Scale (NAS) | 47.5 | 97.5 | Better neuro recovery |
