AI-powered CPR coach outperforms 911 dispatchers in guiding bystander resuscitation

A new study shows that an AI-powered CPR coaching agent can significantly improve survival rates by providing more accurate and comprehensive instructions. ChatCPR scored 100% on guideline-based CPR checklists and outperformed human dispatchers in guiding bystander resuscitation, with a 36-point gap in advanced steps.

Resuscitation science, training and technology leaders launch new self-guided resuscitation learning model nationwide

The American Heart Association and Laerdal Medical have launched Self-Guided Learning, a flexible resuscitation training delivery model, to provide equitable access to high-quality training. The model allows learners to complete HeartCode Complete courses on their own schedule, using advanced simulation technology to verify skills.

Studies find sex-based disparities in transfusion of whole blood in traumatically injured patients

A new study published in Transfusion journal reveals sex-based disparities in the transfusion of whole blood to traumatically injured patients. Women, particularly younger females and those of childbearing potential, are less likely to receive whole blood transfusions compared to men. This disparity is despite whole blood being associa...

TTUHSC conducting study to help patients that experience traumatic blood loss

The Texas Tech University Health Sciences Center is conducting a randomized controlled trial to investigate the effectiveness of calcium and vasopressin in treating severely injured patients who experience significant blood loss. The study, known as CAVALIER, will enroll approximately 1,050 participants aged 18-90.

Lifesaving star

A novel, star-shaped polymer has been developed as a low-volume resuscitant for prehospital treatment of severe hemorrhagic shock. The solution can refill blood vessels without disrupting coagulation, offering an improvement over existing colloidal resuscitants.

Investigating organ donation practices following extracorporeal cardiopulmonary resuscitation

Researchers investigate organ donation practices after extracorporeal cardiopulmonary resuscitation (ECPR), finding delayed organ procurement intervals and lower lung graft survival rates in ECPR groups. The study suggests using ECPR may address the organ shortage crisis by increasing viable organs for transplantation.

Autonomous medical intervention extends ‘golden hour’ for traumatic injuries with emergency air transport

A breakthrough in trauma care has nearly quadrupled the 'golden hour' for treating large animals with internal bleeding during emergency ground and air transport. Researchers used a closed-loop, autonomous intervention system to resuscitate pigs with traumatic injuries, extending their survival time by several hours.

In the resuscitation discussion, do words matter between doctors and patients?

A pilot study found that highly satisfying conversations about CPR preferences occurred regardless of the terms used by doctors. Discussions took less than five minutes on average and were satisfactory to participants. The study suggests physicians should ask all patients their code status, regardless of phrasing used.

Researchers estimate survival chances during CPR for cardiac arrest

A US study published in The BMJ found that a person's chance of surviving while receiving CPR for cardiac arrest declines rapidly from 22% after one minute to less than 1% after 39 minutes. The likelihood of leaving hospital with no major brain damage also decreases significantly after 32 minutes without heartbeat.

Prioritizing circulation before the airway in trauma may improve outcomes for patients with massive bleeding

A literature review found that prioritizing circulation before the airway in trauma patients with major blood loss leads to improved outcomes, including lower mortality rates. This approach, known as CAB, has gained acceptance over the ABC model and is now being recommended by the American College of Surgeons.
