CPR goes high-tech: Transesophageal echocardiography turns blind compressions into precision hits

By conducting the world's first randomized clinical trial, researchers have demonstrated that while overall survival rates remained comparable in this initial phase, TEE-guided precision CPR enhances end-tidal CO2 levels (indicating better CPR quality and forward blood flow), transforming traditional "blind" compressions into a data-driven science. This research, published in JAMA Internal Medicine, paves the way for individually customized resuscitation, challenging global standards to maximize survival for millions worldwide.
