NCT02657733

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • The influence of different breathing rates (normal breathing, tachypnea, and bradypnea) on the accuracy of respiratory rate in breaths per minute as measured by the tested devices compared to a reference device.

    Respiratory rate will be measured with the monitors (Radical-7 device, Nellcor device, Capnostream20p device) and recorded in the following units: Breath/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.

    6 hours

Secondary Outcomes (1)

  • 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 a reference device.

    6 months

Study Arms (1)

Healthy volunteers

OTHER

Respiration rate will be measured using several medical devices: Radical-7, Capnostream20p and Nellcor Bedside Respiratory Patient Monitoring System

Device: Radical-7Device: Nellcor™ Bedside Respiratory Patient Monitoring SystemDevice: Capnostream 20p

Interventions

Radical-7DEVICE

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).

Healthy volunteers
Nellcor™ Bedside Respiratory Patient Monitoring SystemDEVICE

Comparison between 3 different monitors that measure repiratory rate. The participant is connected to 3 monitors at the same time. Nellcor™ Bedside Respiratory Patient Monitoring System - measures respiratory rate according to oximetry respiration rate (RRoxi).

Healthy volunteers
Capnostream 20pDEVICE

Comparison between 3 different monitors that measure respiratory rate. The participant is connected to 3 monitors at the same time. Capnostream 20p- measures respiratory rate according to Capnography (RRetco2).
