During defibrillator application: activate K-1 Yongquan through needles before defibrillation. Unsuccessful CPR: "gold standard"for legal clinical death.RESULTS: Implies comparing two hypotheses: Ho(null hypothesis) demonstrates no association between the two variables studied; Ha(alternative hypothesis) implies some degree of relation between them. Difference between the two treatments is observed. If it is greater than the standard error multiplied by a coefficient of security, the difference is significant: Ha will be accepted and Ho rejected. First we will compare CPR without defibrillator(method "A") and K-1 Yongquan method(method "B"), using percentages of representative samples(treatment "A": 6.4% response, treatment "B": 85% response). If │PA- PB│ is greater than the product of 1.96 times the standard error, the difference is significant. Because │PA- PB│ = 0.786 is greater than 0.098, the difference between 0.064 and 0.85 is statistically significant. Thus, we reject Ho and accept Ha as correct. Thus, it is improbable that chance was responsible for this association. This analysis shows that K-1 Yongquan method has a "quality guarantee". Second, we compare defibrillators("A") with K-1 Yongquan method("B")(treatment "A": 48%, treatment "B": 84%, │PA- PB│= 0.36; │PA- PB│ = 0.36 is greater than SE × 1.96 = 0.0148 and also statistically significant, demonstrating again the comparative value of the Yongquan method. CONCLUSION: The Yongquan resuscitation manoeuver is a non-invasive, non-tiring, costless, and easy-toapply procedure that provides a second chance when other options fail.展开更多
