Patients with OHCA whose blood gas analyses within 5\u200aminutes after receiving ALS at the emergency department (ED) were enrolled. Patients younger than 20\u200ayears old, with cardiac arrest resulting from traumatic or circumstantial causes, with return of spontaneous circulation (ROSC) before ED arrival, lacking record of initial blood gas analysis, and with do-not-resuscitate orders were excluded. The primary outcome of this study was neurological status at hospital discharge.<\/jats:p>\n                    <jats:p>In total, 2034 patients with OHCA were enrolled.

Witnessed OHCA was noted in 571 cases, cardiopulmonary resuscitation was performed before paramedic arrival in 512 (25.2%) cases, and a shockable rhythm was observed in 269 (13.2%).
