Closer monitoring of respiratory pathophysiology by measuring minute ventilation (MV), tidal volume (TV), and respiratory rate (RR) may better identify those most at risk for adverse acute outcomes in a variety of clinical settings.
Currently there is no technology that noninvasively measures the adequacy of ventilation in nonintubated patients. A novel, noninvasive Respiratory Volume Monitor (RVM) has been developed to continuously measure and display minute ventilation (MV), tidal volume (TV), and respiratory rate (RR) in a variety of clinical settings. We demonstrate the RVM’s accuracy and precision as compared with a standard spirometer under a variety of clinically relevant breathing patterns in nonintubated subjects.
Data demonstrated that RVM and spirometer measurements of MV and TV are equivalent in a wide range of ambulatory subjects with an average error <10%.
This study demonstrates RVM’s clinically relevant accuracy and precision in measuring MV, TV, and RR over a 24-hour period and during various breathing patterns. (Anesth Analg 2013;117:00–00)
