| Parameters | CNO | IF | SERVO-i | P value |
| RR (/min) | 42 (±16) | 42 (±16) | 48 (±18) | 0.16 |
| HR (/min) | 166 (±15) | 169 (±16) | 169 (±14) | 0.03 |
| SpO2 (%) | 93 (±5) | 93 (±5) | 93 (±5) | 0.61 |

Values are expressed as mean (SD).
FiO2, fraction of inspired oxygen; HR, heartbeat; IF, Infant Flow; RR, respiratory rate; SpO2, oxygen saturation measured by pulse oximetry; TcPCO2, transcutaneous partial pressure CO2.
