Values are presented as numbers and percentages (%) or mean ± standard deviation (SD).
Group formations were reconstructed at each measurement time (6 times), with Group 1 being IPI:7 and above, and Group 2 being IPI below 7.
IPI: integrated pulmonary index, EtCO2: end-tidal carbon dioxide, MAP: mean arterial pressure, RR: respiratory rate, SpO2: oxygen saturation
