Table 3.
Characteristic | Odds Ratio | 95% Confidence Interval | p-value |
---|---|---|---|
Age (years) | 1.02 | 0.991–1.049 | 0.185 |
Time to ROSC (minutes) | 1.121 | 1.065–1.181 | <0.001 |
Shock | 1.24 | 0.539–2.854 | 0.612 |
Bystander CPR | 0.509 | 0.215–1.203 | 0.124 |
Initial Rhythm PEA/Asystole | 4.975 | 1.953–12.673 | 0.001 |
Maximum PaO2 (mmHg) | 1.485 | 1.032–2.136 | 0.033 |
The odds ratio for maximum PaO2 is for an increment of every 100 mmHg above 54 mmHg. Poor neurological status is defined as CPC ≥ 3. ROSC = Return of Spontaneous Circulation; CPR = Cardiopulmonary Resuscitation; PEA = Pulseless Electrical Activity; Shock = requirement of vasoactive medications to maintain a mean arterial blood pressure greater than or equal to 65 mmHg.
