Integrated pulmonary index can predict respiratory compromise in high‐risk patients in the post‐anesthesia care unit: a prospective, observational study

Table 3 The relationship between parameters at admission in PACU and the incidence of respiratory compromise

Parameters at admission in PACU	RC group	Non-RC group	p-value
Integrated pulmonary index	6.7 ± 2.5	9.0 ± 1.3	< 0.001
SpO₂	95.9 ± 4.2	98.3 ± 1.9	0.04
ETCO₂	37.6 ± 11.9	38.6 ± 6.26	0.94
RR	14.2 ± 6.0	13.6 ± 4.1	0.70

All values reported as mean ± standard deviation
PACU post-anesthesia care unit; RC respiratory compromise; SpO₂ oxyhemoglobin saturation measured by pulse oximetry; ETCO₂ end-tidal carbon dioxide; RR respiratory rate
