Noninvasive, Continuous Monitoring of Acoustic Respiration Rate (RRa®)

Designed to capture the sounds of breathing in a patient’s airway, rainbow Acoustic Monitoring converts acoustic patterns into breathing cycles to calculate respiratory rate.

  • Applied comfortably on the neck or chest to capture the sound of breathing
  • Hear a patient’s breathing remotely from a Patient SafetyNet™* view station
  • Easily monitor respiration rate in fragile neonates and pediatric patients

The Need for Continuous Respiration Monitoring

Respiratory rate (RR) is one of the most sensitive markers of patient
condition and a core aspect of multiple clinical assessment tools.1 It
provides information on clinical deterioration, predicts cardiac arrest, and
supports the diagnosis of severe pneumonia.2

In fact, respiratory conditions are the most common reason for admission
to a neonatal unit in both term and preterm infants.3 And because
neonates are among the most fragile patients, the need for continuous
monitoring without discomfort or irritation is paramount.4

A Gentle Approach: Acoustic Respiration Rate (RRa)

With its streamlined sensor size and weight, along with an adhesive ideal
for use on delicate skin, RRa offers a gentle approach to measuring
respiration rate, prioritizing patient comfort without sacrificing reliability.

Monitoring RRa alongside SpO2 and other physiological parameters on a
single Masimo Pulse CO-Oximeter® can help facilitate more informed
assessment of the most fragile patients.

How Does Acoustic Respiratory Monitoring Work?

Using acoustic signal processing, rainbow Acoustic Monitoring captures the vibrations caused by a patient’s airflow via a sensor worn comfortably on the chest or neck. These vibrations are displayed as a waveform and converted into breath cycles to calculate acoustic respiration rate (RRa), a numeric value.

To help streamline workflows, RRa can be accessed remotely from a Patient SafetyNet view station.

Clinical Evidence

Blood and Fluid Monitoring

In addition to SpHb, the Masimo rainbow SET Pulse CO-Oximetry platform offers Pleth Variability Index, or PVi.

PVi is a measure of the dynamic changes in Perfusion Index (Pi) that occur during one or more respiratory cycles.

When monitored together, SpHb and PVi may provide clinicians with additional insight into a patient’s status.

Provided alongside SpHb on rainbow® Pulse CO-Oximetry sensors, PVi provides a continuous noninvasive measure of the relative variability in the photoplethysmograph (pleth) during respiratory cycles that may be used as a dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adults.7
