| Variable | Group | |
|---|---|---|
| IPC-13.5 min | NPC-13.5 min | |
| N | 5 | 5 |
| Age (weeks) | 6.7 ± 0.5 | 7.1 ± 0.3 |

| Temperature (°C) | 37.4 ± 0.2 | 37.4 ± 0.13 |
| Heart rate (bpm) | 283 ± 21 | 290 ± 28 |
| ET- CO2 (%) | 5.2 ± 0.3 | 5.6 ± 0.4 |
| O2 saturation (%) | 98.8 ± 0.3 | 99.0 ± 0.4 |

Data are shown as mean and standard deviation.
IPC, ischemic preconditioning; ET, end-tidal; BPM, beat per minute; AAR, area at risk; LV, left ventricle; NPC, no ischemic preconditioning.
