Physiological parameters of interest.
| Physiological parameters of interest | |||
| The following parameters are suggested to encourage data collection and stimulate research in a cardiac arrest management. It should be noted that they are not known markers of improved clinical outcome. | |||
| Parameter of interest | Parameter targets | ||
| Systolic blood pressure (mm Hg) | 60 | 70 | 80 |
| Diastolic blood pressure (mm Hg) | 25 | 30 | 40 |
| Central venous pressure (mm Hg) | 5 | 10 | 20 |
| Coronary perfusion pressure (mm Hg) | 10 | 15 | 20 |
| End-tidal CO2 (mm Hg) | 10 | 15 | 20 |
| End-tidal CO2 (kPa) | 1.3 | 2 | 2.7 |
| PH | 7.0 | 7.1 | 7.2 |
| Base excess (mmol/l) | −10 | −7.5 | -5 |
| Oxygen saturation (%) | 70 | 80 | 90 |
| Cerebral oximetry (Near infrared spectroscopy) (%) | 25 | 30 | 40 |
Green, amber and red indicate potential impact of the physiological parameters achieved during cardiac arrest on restoration of spontaneous circulation (ROSC) and could be used to guide future research. Clinical decisions regarding cessation of resuscitation should not be based only on these parameters.
