Patients experiencing in-hospital cardiac arrests at night or on weekends have a significantly lower chance of survival than those who arrest during weekday evenings. This is due to decreased detection and treatment effectiveness, potentially resulting from patient, staff, and hospital factors.
Research found that 30% of patients with ventricular arrhythmia received life-saving defibrillation more than two minutes after cardiac arrest, leading to significantly lower survival rates. Hospital characteristics, such as small size and lack of continuous monitoring, were associated with delayed defibrillation.
Two large-scale studies found no statistically significant difference in survival rates between Chest-Compression-Only CPR and traditional CPR with mouth-to-mouth breathing. This contradicts previous guidelines that recommended interrupting chest compressions for breaths.
