Blinded capnography monitoring - all subjects enrolled

1 subject missing data

Global anesthetic condition classification scale based upon health status assessment with range of ASA I (normal healthy patient) to ASA VI (declared brain dead patient whose organs are being removed for donor purposes). Multiple criteria are considering when assigning a physical status classification to a patient, such as smoking status, Body Mass Index, and medical history. Status was determined by the patient's surgical/anesthesia team. A higher score correlates to poorer outcomes.

The STOP-BANG score is a tool to determine if a patient is at risk for Obstructive Sleep Apnea (OSA). Parameters that are assessed include whether a person snores, is tired, has high blood pressure, or has been observed to stop breathing while asleep, has a Body Mass Index higher than 35 kg/m^2, age, gender, neck circumference. The score ranges from 0 to 8, and includes three risk categories for OSA (Low = 0-2, Intermediate = 3-4, High = 5-8).

Subjects were clinically monitored through standard methods (standard clinical practice at the site), as well as with continuous data collection from the Capnostream monitor for a maximum of 48 hours. The monitoring period started for subjects once they arrived on the ward, for those subjects where opioid therapy was initiated prior to arrival on the hospital ward. Monitoring was permitted to be discontinued after a minimum of 4 hours from the last dose of opioid therapy received or if the subject was discharged from the hospital ward.

No treatments were administered for this study. This study was observational in nature for all subjects. The capnography monitor served primarily as a data collection method. The capnography monitor screen was blinded, and alarms silenced for all subjects.
