Conclusion: End-tidal capnography monitoring can reduce the incidence and duration of hypoxemia during FB in nonintubated patients under sedation. 29, p = 0.019), and the mean lowest SpO 2 value was higher (90.5 vs. Qualitative monitors use a colorimetric device that monitors the end-tidal CO2 (EtCO2) in exhaled gas and changes color depending on the amount of CO2 present.2. 41.7 s, p = 0.029), severe hypoxemic events (SpO 2 < 85%) were observed less frequently (16 vs. In the capnography group, hypoxemia duration was shorter (20.4 vs. Hypoxemia (at least one episode of pulse oximeter oxygen saturation < 90%) was observed in 27 out of 94 patients in the capnography group (29%) and in 42 out of 91 patients in the control group (46% p = 0.014), resulting in an absolute risk difference of −17.4% (95% confidence interval, −31.1 to −3.7). Aetna considers capnography (end-tidal carbon dioxide (PETCO2) monitoring) medically necessary for monitoring of members with congenital central alveolar hypoventilation syndrome. Patient characteristics were well balanced between the two groups. Results: A total of 185 patients were enrolled. Bronchoscopy examiners for the only capnography group were informed of apnea events by alarms and display of the capnography monitor. Methods: Patients undergoing FB under moderate sedation without tracheal intubation were randomly assigned to receive standard monitoring including pulse oximetry or additional capnography monitoring. End-tidal CO2 detection is vital for confirming supraglottic airway placement and for monitoring ventilation rate.
Objectives: The aim of this study was to evaluate the benefit of additional end-tidal capnography monitoring in reducing the incidence of hypoxemia during FB in patients under sedation. Monitor waveform capnography before and immediately after the supraglottic airway is placed. End-tidal capnography is expected as an additional useful monitor for these patients during FB. Capnograph adopts sidestream method to measure the end-tidal carbon dioxide, airway respiration rate and other parameters. Background: Although appropriate sedation is recommended during flexible bronchoscopy (FB), patients are at risk for hypoventilation due to inadvertent oversedation.
