rainbow Acoustic Monitoring®

  • The respiratory signal is separated and processed using acoustic signal processing that leverages Masimo Signal Extraction Technology (SET®) to display continuous respiration rate (RRa) and an acoustic respiration waveform, a visualization of the vibrations caused by the patient’s airflow.
  • Clinicians have the option to use the acoustic sensor to listen to the sound of a patient’s breathing through a point-of-care device at the bedside and remotely from a Masimo Patient SafetyNet™* view station.
  • An adhesive Respiratory Acoustic Sensor (RAS) detects acoustic signals produced by the turbulent airflow in the upper airway that occurs during inhalation and exhalation, while signal processing algorithms convert the acoustic patterns into breath cycles to calculate respiration rate.
  • Continuous monitoring of SpO2 and RRa, as well as other physiologic parameters, on a single Masimo Pulse CO-Oximeter® provides clinicians with more data to make informed care decisions and helps facilitate well rounded patient assessment.

The Need for Continuous Respiration Monitoring

 

Continuous monitoring of respiration rate is especially important for post-surgical patients receiving patient-controlled analgesia for pain management. The Anesthesia Patient Safety Foundation (APSF) and The Joint Commission recommend continuous oxygenation and ventilation monitoring for all patients receiving opioid-based pain medications.1,2 Neonatal intensive care unit (NICU) patients (neonates) need continuous monitoring of vital signs such as respiration rate without causing discomfort or irritation.3 Respiratory conditions are the most common reason for admission to a neonatal unit in both term and preterm infants.4 Respiratory rate (RR) is one of the most sensitive markers of patient condition and a core aspect of multiple clinical assessment tools.5

Pediatric Patient Tolerance

Masimo - Pediatric Patient Tolerance Chart two column
 

15 out of 40 pediatric patients removed the nasal cannula while only one removed the rainbow® acoustic sensor.

In a study of 40 pediatric patients (12 months to 18 years of age) undergoing post-anesthesia care, in which researchers compared acoustic respiration rate monitoring using RRa to nasal capnography, impedance pneumography, and a reference method (counting breaths), researchers found that the difference in bias and precision between RRa and capnography was not significant, but that 97.5% of the patients (39) demonstrated good tolerance of the acoustic sensor, whereas 62.5% (25) demonstrated good tolerance of the nasal cannula. The researchers concluded, “Continuous respiration rate measurement from noninvasive, acoustic monitoring showed good agreement with nasal capnography, but was much better tolerated in post-surgical pediatric patients. Acoustic monitoring has the potential to increase the safety of pediatric patients by providing a reliable and accurate method for the continuous monitoring of respiration rate.”6

Respiratory Acoustic Sensors (RAS)

 

For All Patient Populations - Adult, Pediatric, Infant, and Neonatal

Masimo - RAS-45c Sensor
 

RAS-45

Adult -- Small size with thin, flexible adhesive allows for comfortable application on patients with smaller necks or fragile skin

Infant/Neonatal -- Small size with a chest application site away from the face allows for continuous respiratory rate monitoring without interfering with daily care activities, such as feeding, holding, bathing, and supine positioning

Masimo - RAS-125c Sensor
 

RAS-125c

Adult/ Pediatric -- Breathable cloth allows air to penetrate tape for enhanced adhesion on adult and pediatric patients, including diaphoretic patients
