Noninvasive Respiratory Volume Monitoring Effective for Nonintubated Patients

Boston—Although capnography remains the gold standard for monitoring ventilation in patients undergoing general anesthesia and monitored anesthesia care (MAC), the technology is more challenging in nonintubated patients. In these situations, a noninvasive respiratory volume monitor may be helpful. One such monitor has been found to provide reliable measurements when capnography data are unavailable, and seems unaffected by end-tidal carbon dioxide (CO₂) challenges such as nasal cannula
