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

Questions about this trial
What is this clinical trial studying?
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.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PCCR (percentage of correct compression rate) (time frame: At 1, 2, 3, 4, 5, and 6 minutes after initiation of chest compressions). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2026.
