NCT02715180 | Completed

• 1 other identifier: Hear_position_01
• Study Type: interventional
• Target: 127
• Locations: 0 countries
• Sites: N/A

Brief 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.

Conditions

Cardiopulmonary Resuscitation; Hand Position

Outcome Measures

Primary Outcomes (1)

• proper hand position during CPR using the scout film of low dose chest computed tomography

  proper hand position during CPR based on comparison between expiration with the arms at down position and inspiration the arms at raised position. Measurement will be assessed with a length of xiphoid process to arbitrary center of heart

  five months

Secondary Outcomes (1)

• predicted compressed organs in CPR using the scout film of low dose chest computed tomography Measurement will be assessed with scout film silhouette of organs under quarterly divided sternum.

  five months

Study Arms (1)

Chest computed tomography

OTHER

Low dose chest computed tomography during expiration and inspiration

Radiation: low dose chest computed tomography

Interventions

low dose chest computed tomography RADIATION

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.

Chest computed tomography
