Patient groups divided by variables identified in the regression model | Probability of survival to hospital discharge when CPR was performed for 30Â minutes | Duration of CPR when probability of survival to hospital discharge decreased to 18Â % (minutes) | Duration of CPR when probability of survival to hospital discharge was half the initial probability (minutes) |
---|---|---|---|
Group 1: shockable rhythm (+), lactate level <9 mmol/L (+), hepatic insufficiency (−) | 23 % | 32.3 | 21.7 |
Group 2: shockable rhythm (+), lactate level <9 mmol/L (−), hepatic insufficiency (−) | 13 % | 22.2 | 17.4 |
Group 3: shockable rhythm (−), lactate level <9 mmol/L (+), hepatic insufficiency (−) | 10 % | 17.9 | 16.0 |
Group 4: shockable rhythm (+), lactate level < 9 mmol/L (+), hepatic insufficiency (+) | 8 % | 14.3 | 15.1 |
Group 5: shockable rhythm (−), lactate level < 9 mmol/L (−), hepatic insufficiency (−) | 5 % | 7.8 | 13.8 |
Group 6: shockable rhythm (+), lactate level <9 mmol/L (−), hepatic insufficiency (+) | 4 % | 4.2 | 13.2 |
Group 7: shockable rhythm (−), lactate level <9 mmol/L (+), hepatic insufficiency (+) | 3 % | NA | 12.7 |
