Comparison Between Different Technologies That Measure Respiratory Rate

November 1, 2016 updated by: Oridion
Respiration rate is a critical vital sign that provides early detection of respiratory compromise and patient distress. Continuous monitoring of respiration rate is performed in patients under different clinical conditions, including post-surgery or different respiratory diseases. Clinician observation, pulse oximetry, and capnography are used individually or in combination to monitor ventilation during sedation and on post-surgical patients. The American Society of Anesthesiologists mandates the monitoring of respiration by measuring end tidal carbon dioxide (RRetco2) during procedural sedation and anesthesia. Other techniques for respiration rate measurement include different technologies such as acoustic respiratory rate (RRa). The aim of this study is to compare the accuracy of RRetco2 and RRa under certain respiratory conditions.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Healthy volunteers
Respiration rate will be measured using several medical devices: Radical-7, Capnostream20p and PTAF2 (flow meter)
Device: Radical 7
Comparison between 3 different monitors that measure respiratory rate. The participant is connected to 3 monitors at the same time. Radical 7 measures respiratory rate according to acoustic respiratory rate (RRa).
Device: Capnostream20p
Comparison between 3 different monitors that measure respiratory rate. The participant is connected to 3 monitors at the same time. Capnostream20p measures respiratory rate using capnography (RRetCO2).
Device: PTAF2
Comparison between 3 different monitors that measure respiratory rate. The participant is connected to 3 monitors at the same time. PTAF2 measures respiratory rate using flow pressure (RRflow).
Other Names:
  • Flowmeter

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The influence of different breathing rates.on the accuracy of respiratory rates in breaths per minute as measured by the tested devices compared to the reference device.
Time Frame: six months
Respiratory rate will be measured with the monitors Radical 7 device, Capnostream20p and PTAF2 (flow meter), the latter as a reference device and recorded in the following units: breaths per minute. Differences in accuracy as compared to the reference device and differences in percentage of time in which the device was accurate will be analyzed offline.
six months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The influence of hearing or performing noises on the accuracy of respiratory rates in breaths per minute as measured by the tested devices compared to the reference device.
Time Frame: six months
Respiratory rate will be measured with the monitors Radical 7 device, Capnostream20p and PTAF2 (flow meter), the latter as a reference device and recorded in the following units: breaths per minute. Differences in accuracy as compared to the reference device and differences in percentage of time in which the device indicated respiratory rate values will be analyzed offline.
