Brief Summary
Respiratory depression occurs in labor and delivery; noticeably when neuraxial opioids are given.Pathophysiological respiratory depression -failure to respond to hypercapnia or hypoxia - is challenging to measure clinically.American Society of Anesthesiologist guidelines recommend suitable respiratory monitoring for 24 hours post cesarean delivery (CD). Use of capnograph will enable us to assess breath-by-breathe respiration in a population receiving neuraxial opioids - potentially at risk for respiratory depression. Our aim is to assess our ability to capture maternal postpartum respiratory parameters in a cohort following opioid neuraxial administration for CD.

Outcome Measures
Primary Outcomes (1)
CO2 monitoring
The Capnostream is a portable CO2 monitor with a pulse oximetry module to measure and record SpO2 and heart rate and provides waveform patterns for respratory rate and EtCO2 measurement.
24 hrs
Interventions
The Capnostream capnograph (is registered with the FDA) is supplied by Covidien. The Capnostream is a portable CO2 monitor with a pulse oximetry module to measure and record SpO2 (oxygen saturation) and heart rate continuously. The Capnostream provides waveform patterns for respiratory rate and EtCO2 measurement.
Eligibility Criteria
Women undergoing cesarean delivery with neuraxial anesthesia.
You may qualify if:
- American Society of Anesthesiologists physical status class I or II
- Age between 18 and 45
- Gestational age greater than 37 completed weeks
- Singleton pregnancy.
You may not qualify if:
- Contraindication for neuraxial analgesia (bleeding diathesis, neuropathy, severe scoliosis, previous spine surgery, local anesthetic allergy)
- Allergies to postoperative medication (opioids, NSAIDs, acetaminophen)
- Chronic opioid use
- Opioid administration in the previous 12 hours
- Inability to adequately understand the consent form
- Blocked nose or nasal deformity.
