Ventilatory and Oxygenation Parameters Before (< 2 h) and After (< 2 h and 24 h) Delivery Among 47 Pregnant Patients With COVID-19 Requiring Invasive Mechanical Ventilation in 21 ICUs in Argentina and Colombia During 2021
| Variable | Before Delivery (< 2 h) | After Delivery (< 2 h) | After Delivery (24 h) | P Value |
|---|---|---|---|---|
| PP, cm H2O | 25.6 ± 6.6 | 24 ± 6.7 | 24.6 ± 5.2 | .59 |
| DP, cm H2O | 13.6 ± 4.2 | 12.9 ± 3.9 | 13 ± 4.4 | .69 |
| SC, mL/cm H2O | 28 (22.5-39) | 30 (24.5-44) | 30 (24.5-44) | .058 |
| Pao2 to Fio2 ratio | 134 (100-230) | 168 (136-185) | 192 (132-232.5) | .022a |
| PEEP, cm H2O | 11 ± 3 | 12 ± 4 | 11 ± 2 | .8 |
Data are presented as No. (%), mean ± SD, or median (interquartile range), unless otherwise indicated. DP = driving pressure; PEEP = positive-end expiratory pressure; PP = plateau pressure; SC = static compliance.

In the post hoc Bonferroni analysis, differences were observed between the subgroup before delivery and the subgroup at 24 h after delivery (P = .025).
