Acoustic Respiration Rate (RRa™) is part of the upgradable Masimo rainbow SET® platform—the first to noninvasively and continuously monitor blood constituents and respiration rate.
When used with other clinical variables, RRa may help clinicians assess respiratory status and help determine treatment options.
How It Works
Masimo rainbow Acoustic Monitoring™ noninvasively and continuously measures respiration rate using an innovative adhesive sensor with an integrated acoustic transducer that is easily and comfortably applied to the patient's neck.
Using acoustic signal processing that leverages Masimo's patented revolutionary Signal Extraction Technology (SET®), the respiratory signal is separated and processed to display continuous respiration rate.
"Breathing adequately is what matters most. Masimo Acoustic Respiration Rate provides clinicians with the ability to automatically and continuously monitor the breathing status of post-surgical patients in general care or post-anaesthesia settings—alerting them to the first sign of an abnormal or compromised breathing pattern that may be indicative of airway obstruction or respiratory distress."

Clinical Benefits
Respiration rate is a critical vital sign that provides early detection of respiratory compromise and patient distress
- > Continuous monitoring of respiration rate is especially important for post-surgical patients receiving patient-controlled analgesia (PCA) for pain management as the sedation can induce respiratory depression and place patients at considerable risk of serious injury or death.1-5
- > Although the Anesthesia Patient Safety Foundation (APSF) guidelines include oxygenation and ventilation monitoring in all patients receiving opioids6, current methods for respiration rate monitoring can be limited by reliability or patient tolerance.5-7
- > Masimo rainbow SET Pulse CO-Oximetry and rainbow Acoustic Monitoring help you meet APSF guidelines for monitoring post-operative patients.
Technology Platform
The upgradable Masimo rainbow SET technology platform features the following measurements and calculations:
- > Acoustic Respiration Rate (RRa)
- > Oxygen Saturation (SpO2)
- > Pulse Rate (PR)
- > Perfusion Index (PI)
- > Total Haemoglobin (SpHb®)
- > Oxygen Content (SpOC™)
- > Pleth Variability Index (PVI®)
- > Methaemoglobin (SpMet®)
- > Carboxyhaemoglobin (SpCO®)
All Masimo rainbow measurements and calculations—including Acoustic Respiration Rate (RRa)—are available on the Radical-7™ and Rad-87™ monitor.
