A study by WVU researchers found that exposure to white light at night causes multiple poor outcomes in cardiac arrest models, including greater cell death, more aggressive inflammation, and higher mortality rates. In contrast, dim red light had no detrimental effects.
A Swedish review of out-of-hospital cardiac arrest data shows compression-only CPR increased six-fold and doubled the chance of survival, compared to no CPR. Bystander CPR rates nearly doubled over an 18-year period, with patients receiving standard or hands-only CPR being two times more likely to survive 30 days.
A large Japanese study found that women under 65 were less likely to receive bystander CPR in public locations than men. The researchers speculate that cultural attitudes may influence bystanders and propose better understanding of sex-based disparities are needed to facilitate public health intervention.
In patients without STEMI, immediate coronary angiography did not improve survival at 90 days compared to waiting a few days before undergoing the procedure. Clearing arteries with PCI sooner after cardiac arrest may not necessarily reduce long-term brain damage and its key factor in survival.

A 69-year-old male patient was conscious during CPR after a cardiac arrest, despite efforts to restore a pulse and circulation. The study suggests that the high level of patient awareness was due to good peripheral and cerebral blood flow, but raises questions about proper sedation during resuscitation.
A multicenter trial found that initial laryngeal tube insertion may be associated with better clinical outcomes than endotracheal intubation for out-of-hospital cardiac arrest patients. The study, presented at SAEM18, compared the effectiveness of these two airway management techniques in adult OHCA resuscitation.

A new study by the University of Stirling found that half of Scottish adults are not confident administering CPR, with over a fifth unaware of when it is required. The study's findings suggest priority groups include those who are unemployed, in lower social grades, and elderly.
In humans, a massive wave of electrochemical energy release in the brain occurs after oxygen deprivation, known as 'spreading depolarization', which can trigger pathophysiological cascades. Researchers have found that this event is similar to animal studies and that it remains reversible if circulation is restored before nerve cells die.
Using an automated external defibrillator (AED) increases cardiac arrest survival, especially when applied by a bystander before emergency responders arrive. The American Heart Association found that nearly 66% of victims who received a shock from a publicly-available AED survived to hospital discharge.
