![]() 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. 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). Patient characteristics were well balanced between the two groups. Use of Capnography/End Tidal CO2 monitoring in patients receiving Moderate Sedation, Deep. Capnography uses a sample chamber/sensor placed for optimum evaluation of expired CO2. Results: A total of 185 patients were enrolled. Quantitative waveform capnography is the continuous, noninvasive measurement and graphical display of end-tidal carbon dioxide/ETCO2 (also called PetCO2). Background By continually monitoring end-tidal carbon dioxide concentrations, capnography can detect abnormal ventilation or apnoea early. ![]() 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. ![]() ![]() 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. End-tidal capnography is expected as an additional useful monitor for these patients during FB. Practical uses of end tidal carbon dioxide monitoring in the emergency department. Background: Although appropriate sedation is recommended during flexible bronchoscopy (FB), patients are at risk for hypoventilation due to inadvertent oversedation. Detection of exhaled PCO 2 (end-tidal PCO 2) has proven to be a valuable mechanism to confirm tracheal intubation and to recognize accidental esophageal intubations, among other critical patient. ![]()
