Study Shows Minute Ventilation Improves Safety Up To 65% Over End-Tidal CO2 In Patients Undergoing Procedural Sedation | ||

WALTHAM, Mass., May 6, 2016 /PRNewswire/ -- Respiratory Motion, Inc. – An independent study by the University of Vermont College of Medicine—being presented this week at the Society for Ambulatory Anesthesia conference in Orlando, FL—indicates that Minute Ventilation (MV) monitoring significantly improved patient safety over capnography (EtCO2) in monitoring non-intubated patients for potentially life-threatening opioid-induced respiratory depression during procedural sedation. The study, "Respiratory Volume Monitoring Could Improve Safety in Procedural Sedation," concluded that the use of Respiratory Volume Monitoring (RVM), as a direct measure of adequacy of ventilation, may substantially reduce the amount of time a patient is in "unsafe" MV status, during an endoscopic procedure, by between 45% to 65%. Opioids, commonly used for pain control in patients undergoing orthopedic surgery, can cause opioid-induced respiratory depression (OIRD) and post-operative-apnea (POA), in which patients cease breathing. To reduce the risk of these complications, continuous respiratory monitoring is necessary both for intubated and non-intubated patients (those who are spontaneously breathing and most at risk for opioid-induced respiratory depression). According to the study: "Verification of patient respiratory sufficiency is essential in the fast-paced procedural sedation environment, but dark room conditions and limited access to the patient's airway can make clinical assessment difficult. Pulse oximetry is commonly used for respiratory monitoring, but provides only late indication of respiratory depression, especially with the administration of supplemental oxygen. Capnography has unfortunately proven to be unreliable in non-intubated patients." Minute Ventilation monitoring, also referred to as Respiratory Volume Monitoring (RVM), is a direct, non-invasive measure of respiratory compromise, providing real-time measurements of minute ventilation (MV), tidal volume (TV), and respiratory rate (RR) in both intubated and non-intubated patients. In capnography, variables such as sensor positioning, changes in respiratory patterns, and changes in oxygen supply all distort the measurements in non-intubated patients. Because it is an indirect indicator of respiratory compromise, diagnosis is often delayed and readings are often false. This 73-patient study by the University of Vermont College of Medicine utilized a non-invasive respiratory volume monitor (RVM) providing continuous real-time measurements of minute ventilation (MV), tidal volume, and respiratory rate (RR) to assess the adequacy of ventilation during endoscopy. According to the study's key findings, the use of RVM was directly responsible for a reduction of between 45% and 65% in the percent of time with potentially unsafe MV. "Unsafe" MV was considered less than 40% of Predicted MV. The study states:
