Masimo’s rainbow Acoustic Monitoring (RAM) was useful for monitoring dental patients under intravenous anesthesia, according to a new study published in the Journal of Clinical Monitoring and Computing.

The study compared the respiration rate measurements from RAM and capnography (Psychorich IS nasal cannula and BP-608 Omron Colin monitor) in nonintubated patients with dental anxiety undergoing dental treatment.

A total of 1953 data points of respiratory rate were taken from the start to the end of anesthesia. Over the entire observation period, the results showed a significantly higher detection of respiratory rate by RAM (1884 points, 96.5%) than by capnography.
