Clinical Trial Summary

The almost evidences of the optimal hand position during compression had been based on chest computed tomography (CT) or chest plain films of patients for investigating the effective location for compressing the left ventricle of the heart during cardiopulmonary resuscitation (CPR).

However every study was conducted at full inspired state of respiration. A prospective cohort study to evaluate the proper hand position during CPR based on expired respiratory state CT as the health screening would be needed.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 127
• Est. completion date: December 2015
• Est. primary completion date: December 2015
• Accepts healthy volunteers: Accepts Healthy Volunteers
• Gender: All
• Age group: 19 Years and older

Eligibility

Inclusion Criteria:

• over 18 years of age

• no history of heart or lung disease

• no history of chest or abdominal surgery

Exclusion Criteria:

• abnormal findings in LDCT, which might influence inspiration or expiration, were excluded after image interpretation by the board certified radiologists

Related Conditions & MeSH terms

• Cardiopulmonary Resuscitation
• Hand Position

Intervention

Radiation:
• low dose chest computed tomography
All participants were evaluated 2 scout films during LDCT screenings. The first scout film was obtained while a participant was holding a comfortable expiration with the arms at down position, and the second scout film was obtained while a full inspiration with the arms at raised position. The axial images of LDCT were taken during participants' full inspiration. The radio-opaque marker was attached to the participants' skin where the lowest part of sternum was palpable, because the sternum moves according to the position of arms and respiration.
