Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to learn more about the effect of obstetric epidural anesthesia on regional lung ventilation in healthy parturient women. The main question it aims to answer is whether the initiation or epidural analgesia improves or not regional lung ventilation in healthy women at term during labor.

Participants will be subject to measurements of pulmonary impedance by electric impedance tomography before and after the start of epidural analgesia. No change will be applied to clinical care as a result of this measurement.
