Study Details

Study Description

Brief Summary

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

Condition or Disease	Intervention/Treatment	Phase
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.
