EMS Cardiac Arrest Measures

The prognosis of patients with out of hospital cardiac arrest (OHCA) varies by the initial arrest rhythm. Patients with shockable rhythms such as ventricular tachycardia (VT) or ventricular fibrillation (VF) tend to have better survival than those with non-shockable rhythms including asystole and pulseless electrical activity (PEA). This chart shows the percentage of the documented types of cardiac rhythms that cardiac arrest patients are found to be in at time of resuscitation.

The goal of any “out of hospital cardiac arrest” is to have successful resuscitation, which is also referred to as Return Of Spontaneous Circulation (ROSC).  ROSC is defined as the restoration of a spontaneous perfusing rhythm that results in more than an occasional gasp, fleeting palpated pulse, or arterial waveform. Once ROSC is obtained the main focus would be to maintain ROSC throughout treatment, transport and delivery to the emergency department.  This chart shows that the State’s median percentage of ROSC is 25% and with a few exceptions, Santa Clara County is above that.
