Cardiac Arrest, SuddenNCT07861841
The Influence of the Thoracic Stiffness of CPR Teaching Manikins on the Accuracy of Compression in Cardiopulmonary Resuscitation
A study testing different elasticity coefficients of the manikin device in people with Cardiac Arrest, Sudden and Cardiopulmonary Resuscitation (CPR), run by Tang Ziren at 1 site in China.
Trial summary
This study was a multicenter, prospective, randomized controlled, parallel single-blind study. The purpose of this study is to analyze the effect of compression quality by controlling the thoracic stiffness. Read more about this study

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
different elasticity coefficients of the manikin deviceOther
Different groups used different elasticity coefficients to record participants' compression depth, frequency during the process of ECC, and recorded the data of erroneous compression.
| Study group | Role | What they receive |
|---|---|---|
| 6N/mm group | Placebo comparator | Not described Receives: Other: different elasticity coefficients of the manikin device |
| 8N/mm group | Experimental | Not described Receives: Other: different elasticity coefficients of the manikin device |
What is being measured
The primary outcome is the main question the study is designed to answer.
PCCR (percentage of correct compression rate)
PCCR was defined as the percentage of chest compressions meeting guideline-recommended depth and rate criteria, calculated for each minute after initiation of chest compressions.
Measured: At 1, 2, 3, 4, 5, and 6 minutes after initiation of chest compressions
