Comparing breathing tubes and masks during cardiac arrest resuscitation

When someone has a cardiac arrest in the hospital, doctors need to quickly place a breathing tube to help them survive. This study compares two types of breathing devices—a tracheal tube (which goes down the windpipe) and a supraglottic airway (which sits above the voice box)—to measure how much air is actually reaching the lungs during resuscitation. The researchers will attach a small measurement device to record breathing data during the emergency.

During cardiac arrest, it's hard to know if the breathing devices are working as well as they should be. By measuring actual air volumes delivered by each device, doctors hope to understand which approach helps patients better and how to improve resuscitation techniques.
