Comparison of baseline values of IPI and its components with values during the development of PSH in women with PSH.
| PSH (n = 52) | Basale | PSH Development Time | p |
|---|---|---|---|
| Mean ± SD (Min–Max) | Mean ± SD (Min–Max) | ||
| EtCO2 (mmHg) | 26.8 ± 2.7 (14–32) | 21.3 ± 3.6 (12–31) | <0.001 *b |
| RR/min | 22.6 ± 5.8 (10–36) | 21.0 ± 5.7 (11–36) | 0.104 a |
| SpO2 (%) | 98.1 ± 1.0 (96–100) | 98.8 ± 1.3 (94–100) | <0.001 *b |
| HR (beats/min) | 97.9 ± 17.5 (58–139) | 95.8 ± 28.6 (51–176) | 0.590 a |
| IPI | 7.4 ± 1.4 (2–10) | 6.5 ± 1.9 (2–9) | 0.002 *b |
PSH: postspinal hypotension; SD: standard deviation; EtCO2: end-tidal carbon dioxide; RR: respiratory rate; SpO2: peripheral oxygen saturation; HR: heart rate; IPI: integrated pulmonary index. a Paired sample t-test; b Wilcoxon signed rank test; * p < 0.05.
