A Prospective, Observational, Double-blind (Black-Box) Study Evaluating Incidence, Severity and Predictive Factors of Respiratory Depression and Sleep Disorder Pattern During Postoperative Neuraxial Opioid Analgesia in OSA Screened Negative With BMI>=35 Kg/m2 Obstetric Patients After Cesarean Delivery Using Current Standard Intermittent Postoperative Monitoring Compared to Continuous Pulse Oximetry/Capnography

Non emergent scheduled cesarean sections will be consented to participate in this study of patients who have screened negative for obstructive sleep apnea and who are also BMI>/= 35 to have capnography monitoring postoperatively. The capnography and pulse oximetry will be initiated in the post anesthesia care unit and be worn for 12-24 hours after delivery. Data will be retrieved after that time period in a deidentified fashion. Medication usage will be reviewed as well as the standard of care information from the duramorph monitoring will be retrieved.
