An Observational Study of Post-cesarean Delivery Respiratory Patterns Using a Non-invasive Minute Ventilation Monitor (Exspiron ™ System)

The purpose of this study is to evaluate the breathing patterns of women who undergo cesarean
delivery with spinal or epidural morphine for post-operative pain control in the first day
after surgery. Some women who undergo cesarean delivery may be at risk for respiratory
complications related to opiate administration for post-operative pain. The primary aim of
this study is to evaluate post-operative minute ventilation in women who undergo cesarean
delivery using a novel method of non-invasive minute ventilation monitoring, and to see if
there are predictive risk factors that may predispose women to post-operative
hypoventilation.
