Precisione prognostica del diossido di carbonio endotidale nell'arresto cardiaco: una revisione sistematica e meta-analisi.

BACKGROUND: Cardiac arrest, a critical emergency with high fatality rates, needs accurate early predictors of resuscitation outcomes. End-tidal carbon dioxide (ETCO2) monitoring, reflecting tissue perfusion and metabolic activity, is highlighted in guidelines for predicting return of spontaneous circulation (ROSC). This systematic review and meta-analysis evaluates the prognostic accuracy of ETCO2 at various time points and cut-offs to enhance clinical decision-making during cardiac arrest. METHODS: A systematic search of MEDLINE, Embase and the Cochrane Library identified relevant prognostic accuracy studies. Inclusion criteria were original articles reporting prognostic accuracy of ETCO2
