An interventional study of defibrillator electrode pads in Cardiac Arrest (CA), sponsored by Oregon Health and Science University. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-14.
Sponsored by Oregon Health and Science University · Not applicable, Interventional, and Treatment
The purpose of this study is to compare the effectiveness of two defibrillator pad placements, one where pads are placed on the front of the chest and back (anterior-posterior [AP]) and one where the pads are placed on the front and side of the chest (anterior-lateral [AL]), for the treatment of cardiac arrest. Both pad placement locations are recommended for use by the American Heart Association (AHA) and International Liaison Committee on Resuscitation (ILCOR) and are used in standard treatment. The investigators are hoping to find out if one pad position is more effective than the other in the treatment of cardiac arrest.

Start is estimated for Apr 2027; primary completion for Jun 2029, 26 months later.
Of 204 non-industry interventional studies with no phase under Heart Arrest, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 47. This study's planned 26 months is below that.
Counting every sponsor, half of 218 studies reached it within 28 months; a quarter within 10 and three quarters within 47.
