Calculated safe durations of HCA at different temperatures with regard to cerebral metabolic rate and by McCullough et al. [

| Temperature (°C)/level of hypothermia | Cerebral metabolic rate (% of baseline) | Calculated safe duration of HCA (min) |
| 37 (normothermia) | 100 | 5 | 30 (moderate) | 56 (52–60) | 9 (8–10) | 25 (deep) | 37 (33–42) | 14 (12–15) | 20 (profound) | 24 (21–29) | 21 (17–24) | 15 (profound) | 16 (13–20) | 31 (25–38) | 10 (ultra profound) | 11 (8–14) | 45 (36–62) |
