Clinical Utility of Capnography in the PACU( Post-anaesthesia Care Unit)

A Multi-Center Pilot Observational Trial to Quantify the Potential Clinical Utility of Capnography in the PACU

Multi-center observational trial with study device blinded in order to assess in parallel standard monitoring and intervention practices related to management of respiratory compromise in the post-anaesthesia care unit (PACU)

All Study device information is blinded to medical staff but the Study Coordinator will have full access to device measurements, alarms, notification and events via a local Wi-Fi hub sent to a portable tablet. The tablet Case Report Form (CRF) will allow all observation be inserted with a time stamp on the electronic device data. In addition, all electronic data will be collected from the bedside monitor.

Inclusion Criteria:

1. Adult ≥ 18 years of age
2. ASA Score II - IV (American Society of Anaesthesiologists Score)
3. Patients booked for a surgical procedure requiring general anesthesia care
4. Expected duration of general anesthesia to be > 1.5 hours
5. Expected to receive intraoperative opioids
6. Expected to be transferred to the PACU from the operating room
7. Patients with an expected duration in the PACU ≥ 45 minutes
8. Expected to be transferred from the PACU to an in-patient setting

Exclusion Criteria:

1. Patients expected to be discharged from the hospital when discharged from the PACU
2. Subjects who will have oral/nasal surgery that may prevent wearing an oral/nasal capnography sampling filterline.
3. Subjects with a history of severe contact allergies that may cause a reaction to standard adhesive materials found in pulse oximetry sensors.
4. Patients with skin lesions or physical deformities that would prevent the application of finger sensors for optimal performance.
5. A female known to be pregnant.
