Brief Summary:
Pregnancy promotes respiratory system's restrictive component. This study observes the generation of atelectasis during labor.

Condition or disease Intervention/treatment
Delivery, Obstetric Cesarean Section Labor Respiration Disorders Atelectasis Radiation: CT scan

Detailed Description:
Pregnancy causes restriction of diaphragm movements as well as higher resistive component to the respiratory system. Spirometry studies have shown that the supine position increases risks of hypoxemia. There seems to be only casual observation regarding the generation of atelectasis during labor.
